Solution #3: Mix of improvements + Solution #1 (letting the user choose)
Written by franco.valoppi the 26 Aug 09 at 03:47.
I think that even using proprietary driver may make it more compatible, always let the user to choose.

On the other hand I have some other ideas to improve performance (probably already implemented):
- Memory trim and garbage collection, before hitbernating.
- Memory Defrag.
- Exclude System Prefetched data from hibernate files. I mean memory used with programs already closed but still in memory in the case you want to open them again.

Solution #4: Add an idle option
Written by qwerty800 the 19 Sep 09 at 14:54.
As a temporary solution, we should add an "idle" option to ubuntu.

Since suspend and hibernate both invole creating a system image and storing it in the ram/in the swap, until we fix this, we need to find another alternative to this.

The only alternative remaining is to leave your computer open during all the night!

Well, my idea is to add an "Idle" option, that would:
-Suspend most of the programs
-Lower the CPU clocking (If possible)
-Lower the fan speed (If possible, trying to emit the less noise possible)
-Lower the HDD speed (If possible)
-Lock the screen

That way, we could still avoid energy wasting, while waiting for a working sleep mode.

I think this is a big issue, however, I believe it is a bad idea to use non-free drivers to accomplish it.

It's a big issue. In my case, I had problems with suspend after enabling restricted nvidia drivers. Luckily, I have found easy fix at ubuntu forums.

I know it is super complicated to fix this because it is hardware dependent, but most people take this features for granted and it is very annoying to find out that hibernate/standby in Ubuntu are equivalent to shutdown/restart.
The number of Laptops is growing and will continue to grow so good working stand by and hibernate are really needed.

I've been having a terrible time getting my wireless working when coming back from a suspend or hibernate on my m1330n any time I change classes or put my computer in my bag when I come back it's 50/50 whether I'm going to be able to get my wireless working again :(

g33kph4c3 wrote on the 29 Feb 08 at 00:25
This is a big bother for me. I try to suspend my laptop when I go to and from class, and roughly half of the time when resuming from suspend I just get a black screen and have to hold the power button and reboot, losing everything that I had open. Sometimes, it won't even suspend, but the screen turns black for a minute before coming back, but I usually find this out after it has been in my backpack coming too and from class, and the laptop is nearly overheating.

jamessnell wrote on the 29 Feb 08 at 00:44
This would definitely improve the experience for many mobile users. I find mac laptops tend to suspend and resume very gracefully, Ubuntu should mimic that. I find my new eee pc running Ubuntu dies when suspended with a full initial battery charge in what seems like 8 hours or so. My macbook seems to last days. Also my eee takes a really long time to resume from suspend, I sometimes lose the machine as I can't get the display back, though most of the time I just get a black background for 10-15 seconds before X seems to come back.

This is a high-value subject!

deadowl wrote on the 29 Feb 08 at 00:44
The intel driver is definitely not configured well on my machine.

I have way more problems than with suspend and hibernate.

1. Suspend usually works, but not always. Often the mouse won't move after coming out of suspend.
2. Every time I've tried hibernate, my computer doesn't come back to life.
3. When I connect to a VGA (external monitor), horrible things happen. I have to change resolutions manually (something that ought to be done automatically, really). I don't know if this is a television problem, but when I connect VGA to my television, everything but the eject button stops working until it's unplugged and plugged in again (probably is an Insignia television issue).

Hibernation is a massive issue for me as well with my HP tc4200. It will just crash when coming out of hibernation every single time.

sanktnelson wrote on the 29 Feb 08 at 01:13
What also needs to be fixed is the speed of hibernate and wakeup! Aside from the fact that I had to install a hardy kernel on gutsy to get suspend to work at all, suspending and resuming is actually much slower than a full reboot.

This could be fixed by switching to suspend 2, when I was using this on my debian box, suspend and wakeup was an order of magnitude faster.

Nowadays sleep/hibernate is given for granted. That it doesn't work at all in many laptops makes ubuntu look very bad.
This is a must have just to be in the race.

James Paige wrote on the 29 Feb 08 at 02:37
the only way I can get hibernate to work reliably on feisty and gutsy is to manually compile a kernel with the tuxonice patches, and even then it hibernates and resumes much slower than the Windows XP partition on the same Laptop :(

johno wrote on the 29 Feb 08 at 02:57
Suspend/Hibernate support seems to be getting worse. I used to be able to suspend and hibernate my AMD/ATI desktop, but that support broke sometime in Feisty with updates. Then my intel video laptop broke all suspend/hibernate with Gutsy.

Suspend/Hibernate is a fundamental feature that should be supported where at all possible. With this working, there is also much less pressure to improve boot times.

Kadaz wrote on the 29 Feb 08 at 03:01
Suspend and hibernate working fine normally, but it'll cause my laptop unable to recover from suspend and hibernate when the mplayer application is running.
In that case, I've no choice but to press the power button to force reboot.

rozen wrote on the 29 Feb 08 at 03:14
Hugh issue, even with desktops. My desktop burns 200 watts; 5000 such machines left on because suspend/resume doesn't work wastes a megawatt. It is much more important than eye candy.

Suspend/resume worked with Fiesty, but is a crap shoot on Gutsy. On my machine every thing works on resume but the usb-keyboard until I restart the x server using my usb-mouse. My machine is a Dell XPS 410 with proprietary nvida drivers.

I've worked for a Linux distro myself. I understand how complicated this is, but it's a really big deal - or dealbreaker for many. I own an IBM/Lenovo T60 laptop and I have not been able to suspend or hibernate for almost a year now. This is simply not acceptable. I get it - the fault lies with ATI and their fglrx driver, but the problem is that this series of laptops is one of the most popular in the world. It's just plain embarrassing that Linux in general, and Ubuntu do not correctly support this hardware. Ubuntu, and other distros, should be front and center loudly proclaiming that ATI's closed-source video drivers _do not work_ If they cannot get things right, then open source them so that you, and other open source proponents can.

The Ubuntu responses to the endless posts about this issue on the bug-tracking system are not acceptable. This issue is a showstopper and must be fixed, no matter how painful. If the distro won't run on mainstream, business hardware used by millions around the world - well, it's dead at the starting gate.

Please - speak for us end-users and get in the face of ATI (now AMD) and others to get this fixed.

Many, many thanks for creating a truly impressive distro.

trjonescp wrote on the 29 Feb 08 at 05:09
rozen is right on this one. The amount of power wasted each year because laptop *and* desktop users are not able to suspend and instead just leave their machines on has got to be HUGE.

kallahorn wrote on the 29 Feb 08 at 05:12
Yeah, so this is the only thing keeping me back from using Ubuntu as my main distro on my laptop. :(

It failed to work at all pre-Feisty, worked with additional hacks in Feisty, and is broken again in Gutsy.

This is NOT the fault of Ubuntu.

This is the fault of INTEL for refusing to open the BIOS or to provide sufficient documentation for the chipset and processor.

The reason that Intel doesn't open up the BIOS is that it has agreed with Phoenix Technologies and American Megatrends to protect their markets from competition from open source.

I know this because I own a company that manufacturers computers. I tried to get from Intel technical documentation to solve this problem. Intel's engineers candidly told me that they were prohibited from releasing the information because the company had agreed to protect Phoenix.

I don't know "why" this works, but it does for my Thinkpad X60s. I suspect its something that will work for others, since its a bios level thing, and that relates to the previous post.

1. sudo gedit /boot/grub/menu.lst
2. find the grub menu line that is the ubuntu default .. the first one that appears, that will look like this:
title Ubuntu 7.10, kernel 2.6.22-14-generic
root (hd0,0)
kernel ....... etc

3. Add the following to the end of the "kernel" line:

acpi_sleep s3_bios

Here is my "kernel" line.
kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=b6e33b4a-d2ec-4107-9aaa-8956ed669d82 ro quiet splash acpi_sleep s3_bios

4. reboot computer

Now resume works every time.

This is the biggest problem for Ubuntu at the moment. Power saving issues are really important for many users, and it is really annoying that they don't work. A minimal workaround would be to include a diagnostic tool, which gives a warning when the user tries to suspend/hibernate the system, if it fails, or something.

I'm having huge issues with it as well, especially since I'm using nVidia restricted drivers (via Envy), and I have a dual-core AMD64 processor, so I'm doubly screwed. These days I just shut my computer down every night, when I'd rather leave it in suspend or hibernate so that it will come back on more quickly.

changlinn wrote on the 29 Feb 08 at 08:34
This is a huge issue with windows as well from what I have seen. So don't be disheartened, realistically though, I have seen less issues with my ubuntu than I have with clients Windows, even Vista.
For this reason I don't think it is as big an issue as others that are out there.

Lars Noodén wrote on the 29 Feb 08 at 08:54
This is important for notebook users. One mode does not let the computer wake back up. The other sometimes does, but seems to run the CPU full out the whole time the lid is closed. Could be a fire hazard or equipment hazard that way if it's packed away in an air tight case or amongst flammables.

kuahyeow wrote on the 29 Feb 08 at 09:03
Agreed that this is a major problem. Must note that the problem mostly lies with proprietary drivers, which people seem to turn on for 3D and compiz. Doesn't mean that should hang back and let ATI and NVIDIA slowly fix at their own pace. Either support 3D in open drivers or make hibernate work.

However, even with hibernate problems, I'm running Ubuntu on fglrx with compiz-fusion full as it gives me an awesome user experience. Guess that kills off my battery life, so I'm stuck to a/c power.

pjotr123 wrote on the 29 Feb 08 at 09:29
This is a big problem!

It has nothing to do with proprietary drivers for video cards: because I have this problem on two systems with Intel video cards, which run on the usual open source drivers.

Please fix it.

Greyor wrote on the 29 Feb 08 at 09:34
I know that fglrx causes problems in some cases, so yes, it does have to do with proprietary video cards. The problem is not *only* with proprietary video cards, but it certainly affects them adversely.

A resounding endorsement of fixing that. #1 for sure.

My first experience with Linux a few years ago was trying to install it on an IBM T20, which I found out in the course of my frustration and research, was an exception and did not play nice with Linux at all on the issue of suspend and resume while being one of the most popular laptops of its day. It seemed to me at the time that there was something fundamentally wrong with Linux because even Windows 98 could suspend a T20. This left me with a negative impression that has lasted for some time even though I am a Linux fan and dual boot every machine I own. Since then I've learned more but nearly every computer I've tried to use it on has had an issue with it not working without having to address some issue. To use a MS phrase, it leaves a bad "OOBE" (out of box experience). The failure of Linux to do something fundamental like that produces its own "FUD" due to the logic that "there's never just one cockroach"

Yes! I am using ubuntu 7.10 on laptop and desktop and have issues about Hibernate on laptop yet.

I just realize this issue is about nvidia (restrict) driver. After active this driver hibernate does not works.

What happens:
- When pressed hibernate button the system is successful hibernated, but... when resuming the screen got stuck on a "white" panel filling all the screen. After a few seconds it show some "blurs" on the screen and the system freezes.

+1 vote. This issue is so annoying that I have spent a VERY good deal of the time since I half-switched to Ubuntu trying to fix this (first on a Thinkpad R50e, where I discovered that I had to somehow break - dunno how still, it was serendipity - 3d support of the intel i810 driver to get it working; and now Dell Inspiron 6400, where intel wireless and nvidia video card drivers gave me lots of problems).

One thing, though. In this year fiddling around I found out that to fix or at least improve the problems with closed drivers it was sufficient to add some lines to the acpi, saying to leave some modules in the kernel or stop some services. My question then becomes, why when I install one of these drivers does the system NOT take care of this work which I have to do manually? I do not think it would be that hard to add some minor script so that restricted manager takes care of this, using the huge feedback already existing to create the base database of necessary hacks to the acpi-support (or any other file, I am not knowledgeable enough to tell where else one must act).

It seems to me that Ubuntu has mainly targeted the Desktop pcs. There Ubuntu rocks (ever put a desktop pc into suspend? yeah, me neither). But as laptops are continuously spreading in the user-base, IMHO Ubuntu should focus more on those to be a runner in the mid to long term.

Just my 2¢ :)

slkwcy wrote on the 29 Feb 08 at 15:54
This issue really gave me a big headache.

I had tried so hard to find solutions to fix this only got to nowhere.

And this Suspend and Hibernate have never been stable in term of one day I can get it working; usually after system was setup the way I wanted it, then failed the next day. So sometimes I would decide to reinstall the OS again only to lose all the settings and software I would have installed.

I am using a HP DV9xxx laptop. And what I have found so far, is that when I need to use special parameters at the boot time, like apm=off noapic and etc, then this function usually fail.

At one time, I found i386 edition can be loaded without using any of these parameters and the AMD64 one would always required.

But in summary, please have this function to be fixed perhaps in the near release.

Thanks!

Yes, this is a big one. Here's my experience on my averatec 2300 (amd turion); in feisty sleep/hib/etc worked fine. I upgraded to gutsy and that action completely broke. After the screen saver timed out and control was passed to hibernate the x server would go *snap* and leave the screen all white and strange, requiring a reboot. I went back to feisty, which didn't resolve the problem. I re-installed fiesty one more time doing a complete wipe of the hard drive. This finally got me back to a working situation. Other than this experience however my time with ubuntu has been really great.

Neither Suspend or Hibernate work on my installation of Gutsy. It did not work on Feisty or Edgy either. I am on a Dell Inspiron 8600. It seems like X fails because there is no video, but I have not done much to research. In my mind, this is there for convenience and should work "out of the box". I'm a Linux admin and do not mind tinkering with it myself, but if Ubuntu wants to convert more winders users, this will have to just work.

I would like to mention explicitly that this is as PC issue too, not just a laptop. From a green perspective and also from a money perspective. I don't want my PC burning extra energy even though it's plugged into the wall. Currently both hibernate AND suspend lock up my desktop computer, so I end up having to wait for it to boot every evening when I come home and then shutting it down before bed time.

Suspend which I use(d) daily worked perfectly on Feisty with my Lenovo v100. This was the one thing that Gutsy broke on my system. Fixing for Hardy is an absolute priority.

Suspend/Hibernate is a one big pain I'm living with when using Ubuntu. I have Acer Travelmate 8204. The system never comes up from suspend mode. It would be nice if Ubuntu can fix this regardless of laptop/desktop.

woohooo thanks cappy, now my suspend seems to be working pretty much without a hitch. I can't thank you enough for the tip (nor can I believe that I looked for so long and it ended up being something so simple). I still do think this is the most pressing issue with ubuntu. Once people see my laptop running compiz they flip at how cool it looks. But when they see it struggling to make it out of suspend they're normally a bit taken back.

ACPI S3 is the holy grail of suspend and hibernate. When they work they are just plain awesome. However they are kernel and acpi support related. The acpi standard was poorly designed (Google for Linus'es comments if you want to see some quite bitter text) and the vendors keep changing things constantly.

What would really be required to "fix suspend and hibernate" are three things. First of all, the rare breed: C wizards that are able to work with Linux kernel. Second, hardware donations (motherboards and/or complete systems) to the developers. This could however be substituted with giving SSH access to your computer - major trust issue but sometimes doable. Third, support from the vendors. (docs etc)

Hibernate/resume works great for me (Dell Inspiron 5100) except for the fact that when I hibernate, I get a screen full of USB debugging information instead of something telling me the system is in the process of hibernating.

For a user new to Linux, hibernating bringing up a screen full of techo-babble is a Bad Thing, and they may never hibernate again.

With that said, the core issue is making sure hibernate works at all. Making it user-friendly is just icing on the cake.

rawsausage raised good points. There are challenges, but with all this interest, there should be things that can be done. I'd suggest:

* Promote a standard test procedure and related tools to probe the hardware and try out the different methods of suspending.

* Develop a reporting procedure where people can report the behaviour of their systems to the different tests

* Perhaps a suspend-test package that will automate some of this, and try out the suspend options, sending back the debugging information to a database.

The test/debug tools package would probably need to change regularly (and require re-testing) as developers gain new ideas about how to fix specific computers, and what different things to probe.

Basically, rather than (or in addition to) developers getting donation PCs or SSH access, if the testing procedure is automated, they can do the tests in parallel on thousands of PCs at once, and all developers can benefit from the tests others have made.

Both work (most of the time) on my Compaq Presario V6402CA, but sometimes it will refuse to suspend/hibernate (goes black screen, but then "wakes back up" immediately.

Also annoying, I tell power manager to leave the PC on when plugged in but it goes to sleep anyway.

With a lot of effort I got my Dell D830 to suspend properly most of the time. Even now I can't really "trust" it, you have to watch it carefully to make sure it really suspends when you close the lid. Occasionally the mouse and keyboard don't work when you unsuspend.

I've never gotten hibernate to work.

I can understand a lot of people find this is a major issue, but this isn't something that ubuntu can do much about.

For me, when using the opensource ATi driver, suspend works like a charm. Using the closed source driver, it doesn't work at all. I bet the same goes for 90% of the people talking about this 'bug'. The issue here isn't suspend resume per-say, but rather the closed source drivers. Get those fixed, and it's all fixed.

i think suspend and hibernate should be also quick in going and coming back, default system takes more time than a normal reboot... otherwise they're kinda useless.

Most definitely a bit issue for people moving to Linux.
I don't think it should be considered a Ubuntu problem more of an general Linux problem.

I guess Ubuntu developers can do something about it to a certain extend. What I see as the complex issue is not only what should be done to fix, but how much time Ubuntu should spend on it.

I am not sure how Ubuntu and other distribution / kernel people keep record of what is broken / what works when it come to Suspend.
What I can see is Ubuntu as a big active community, if there was a big Suspend issue database or the-like that would open up, I am sure quite a lot of people to help to provide useful information.
Well it's just one idea... I don't know what the developer need the more for fixing those suspend issue.

this is THE number one reason I have not yet switched to Ubuntu. Hibernate just doesn't work (suspend kinda does nwo). That's the major showstopper. A laptop OS without proper working laptop features is just not possible. Please Ubuntuaniacs, fix this.

johno wrote on the 2 Mar 08 at 13:31
Regarding the posts that this isn't something that Ubuntu can do much about, I don't think that completely true. It partly is packaging and documentation, because currently there are several different suspend methods, each with different options. Currently Ubuntu pushes just one of those with one set of options via the graphical suspend/hibernate buttons.

There is also Suspend2, tuxonice, and other suspend methods. However, currently there isn't much current documentation about what is available, and the differences between those.

A package could be developed for people willing to fiddle more that simply click "hibernate" and observe it does/doesn't work. - instead trying the different options, with/without X, with different X driver etc..

It 'kind of' works for me on my laptop, but not flawlessly.

Suspend/standy works when I select it manually from the menu. Even though klaptopdmanager/daemon is set up to suspend when closing the lid, this only works occasionally. Most of the times, it just starts the screensaver.

Hibernation works, but takes extremely long when comparing eg to Windows.

In both cases, when coming back up, it happens quite often that I see my desktop and then it goes into suspend mode again, so I have to start it one more time before I can actually use the laptop.

No big issues but it would be nice if this could be better.

Alighieri wrote on the 3 Mar 08 at 00:17
I agree it is important, but you have it all backwards. The problem as others have said is that each laptop model is different and supporting them all reliably is impossible. Someone has to be paid to make it work, and generally the development work and tweaking is included in the purchase price, but only in a few cases is Ubu the target.

So what needs to happen? The Linux community needs to forward a hardware standard for which Linux is guaranteed to work. Make a "Guaranteed to work with Linux" logo and certification process. This is bigger than Ubu/Canonical and probably needs to be addressed by the Linux Foundation and broader community. Unfortunately, the Linux Foundation has limited pockets and at least one of their major employees (rhymes with highness) appears not to use a laptop (or at least has stated he's only really interested in desktop hibernate).

Short of that, the only bandaid solution is to have laptop-model specific packages that are maintained by the community. Installing these packages would do a "best practices" tweaking of the system.

In feisty on my laptop, a Gateway MT3707, wireless and suspend and hibernate worked out of box. There was sound as well.

Now, in gutsy, wireless causes a kernel panic upon connect (so I'm forced to use ndiswrapper), sound doesn't work and I needed to compile Alsa from source and apply a patch that isn't going to go upstream, and suspend and hibernate doesn't work.

Interestingly enough, every time I fix sound, after every kernel update they push, I have to recompile alsa.

I really just want suspend and hibernate to work. The other problems I can deal with, but this is ridiculous. I'm actually thinking of switching to another distro.

Taking that there is a working solution for this, I just cannot understand how long Ubuntu can ignore this. Suspend2 or TuxOnIce (http://www.tuxonice.net/) as it is called nowadays solves this most requested feature easily. Why not implement it then?

vexorian wrote on the 3 Mar 08 at 16:33
My take: Don't bother.

Focus on speeding up booting and shut down times. Remove hibernate and suspend buttons for default.

Hibernation takes ages to be done when you have a lot of RAM anyways. And suspend does not really save energy.

If booting and shut down times could be halved we wouldn't even need these things.

If you really want to keep hibernate and suspend, improve them but please, avoid proprietary drivers, I don't want to see people's freedom reduced for such unnecessary features.

vexorian: S3 suspend does save a lot energy. On the desktops I've tested, S3 suspend power supply draw is only slightly above the "off" power leakage. Don't confuse it with S1 suspend - which indeed doesn't save energy.

If suspend and hibernate were working, then we wouldn't need to worry so much about boot times.

The idea is not talking about using proprietary drivers to do it. It is talking about making it work even when people are using proprietary video drivers. If anything, if you wanted to remove proprietary driver dependency, you would be better off encouraging suspend - because it is one of the things that is driving people to the open source video drivers.

Thanks for all your comments. We strive to improve Ubuntu with every release and this feedback is important to us. Here are a few thoughts in getting suspend and hibernate to work:

1. It is very complex to get working because it depends on every peripheral driver on the system behaving correctly. And sometimes there are just buggy drivers.
2. The single biggest culprit preventing suspend/hibernate is the video driver.
3. With binary drivers (mainly ATI and Nvidia), we do not have _any_ control over making these drivers behave - so users are left to choose between better 3D support or hibernate.
4. Suspend2 suffers from lack of support upstream (Linus') tree. Coupled with the fact that the patch is very intrusive, it makes maintenance of the patch harder for Ubuntu.
5. As has been shown recently on LKML and various talks [1], both the swsusp and suspend2 (tuxonice) suffer from significant design drawbacks, so that they may never work correctly. There is new work ongoing on using a kexec-based approach that is being currently seen as the successor to the current design.
6. Using open drivers has a better chance of success. If that doesn't work, I urge you to file bugs on launchpad.net so that we might try to fix those.
7. References [2] and [3] are pointers to further debugging your suspend/hibernate issues. Help us in fixing your machines.

Amit

No mather how complicated it is to fix, this is a show stopper for most people. It is required to work out of the box like it does in any modern respectable OS. I used ubuntu with proprietary Graphic driver because these are the one that allow me to use my graphic adapter to its full potential. Using my graphic adapter to its full potential is the main reason why I did by a graphic adapter, so it should not be a reason for not having the possibility to suspend and resume. it is much more important imho than having a desktop cube. It can mean 150$/year in economie when used overnight instead of leaving it always on. This is for me the most anoying bug that there is in ubuntu.

amitk (Ubuntu developer) wrote on the 5 Mar 08 at 00:31
Hi Julien,

I am willing to hear suggestions on how we can get proprietary drivers vendors to co-operate with us. Most of the Linux and *BSD communities would be interested in finding a solution to this problem.

One solution that is encouraged by these communities is to ask users to vote with their wallets - buy hardware that ships with open drivers (or atleast open specifications). Most Intel graphics chips[1] and many ATI ones[2][3] now have open drivers or are working towards open drivers. So the expectation is that these problems will go away, but it will take some time.

In the meanwhile, if there is something that works on another Linux distros but not on Ubuntu, we want to hear about it.

Amit

Last weekend i upgraded to hardy alpha5 and although I was aware of the meaining of "alpha" and I want to contribute, I can't understand why things break that worked before in gutsy....

Hardware:
Samsung P35 notebook, ATI Radeon 9700 Mobility (r300) with free drivers, ipw2200 WLAN

Before:
Gutsy, s2ram (suspend) works like a charm (needs only vbe restore)

Now:
Hardy, freeze and black screen during resume

I have to go deep into the suspend/resume process and debug it.
https://wiki.ubuntu.com/DebuggingGNOMEPowerManager will hopefully help ....

*suggestion*:
Wouldn't it be possible to help the user migrating a working setup to the new pm-tools based infrastructure? Like asking
- "Does suspend/resume work for you?" Y/n
- "Shall I try to migrate the old settings?" Y/n
Additionaly after a resume the user is asked, if the resume worked as expected. In case of a failure either the default settings may be loaded or some probing script may be started to evaluate a working setup AND publish the results.

I like the way a MacBook goes to 'sleep' when you close the lid. It instantly writes everything to RAM and only uses a tiny fraction of power. Upon reopening the lid, you can resume your work instantly.

From a usability perspective, this is better than hibernate. Current huge amounts of RAM (up to 4 GB) take almost as much time to write to disk then plain old rebooting.

The only 'drawback' of Macbook sleep being that you can't swap batteries, because it would purge RAM. But why not find an adapter instead? I have heard reports of Macbooks that can be in the sleep state for days and still be used.

johno wrote on the 8 Mar 08 at 22:43
That MacBook behaviour described is "S3 suspend", also known as "suspend to RAM" to differentiate against hibernate, which is also known as "suspend to disk". There is also a mode that keeps the data in RAM, as well a writing it to disk - and the disk image only used on resume if the power was lost.

S3 Suspend is good on desktops too, where the current draw is typically very little more than the "off" leakage current.

S3 Suspend is theoretically implemented in Ubuntu, but the problem is there is just so much hardware that doesn't work properly with it, and there isn't much coherent documentation about how to get it going when it doesn't "just work" .. hence the demand here for it to be fixed.

hunt.topher wrote on the 10 Mar 08 at 18:20
For me, both suspend and hibernate are slow, jerky, not as aesthetic as shutting down (screen pixellates and blinks), and disrupt services like the volume manager. These bugs really make suspend and hibernate useless to me at this point; shutting down is just much more convenient.

Well, that quick fix doesn't really work for gutsy, because the s2ram has been deliberately removed because apparently we don't need it and it would be confusing to us to have it available.

On the other hand, for me the following works on my Dell D400,

sudo apt-get install pm-utils

now the pm-suspend does s3 suspend correctly, and it seems to also work through the graphical option on the shutdown menu

yztlyrn wrote on the 12 Mar 08 at 15:18
One way to fix this:
1. Ask the user "Is this a Laptop?" during installation.
2. If yes as user "What brand laptop is it?"
3. Taylor installation of APM to fit the laptop
4. If it is an unrecognized brand inform the user that suspend/hibernate may have problems

johno wrote on the 12 Mar 08 at 22:43
Though being a laptop or not isn't all that relevant - it applies equally to desktops and laptops. Also the question of which is the right way to "taylor" the installation isn't clear. There seems to be a bit of a power-play going on between three different suspend/hibernate projects, and each think they are the right way to go. Ubuntu has chosen its way, and so would recommend that as the best solution in all cases.

For each method, it's also an issue of knowing what is the right way to do it for each model. That is the hard part. Once that's known, then the model that the user has can pretty much be auto-detected.

I think what really needs better support are the users with some technical know-how to do some level of debugging. That's less than 1% of users, who can then do directed debugging on their own hardware to better gather and incorporate that information. The results of that would then flow on to all users. The problem for that 1% is that the documentation is rather haphazard, and much is out of date. It would be good if there were an official ubuntu wiki that kept up to date with how things should be done for those users prepared to do a bit of debugging and information-gathering.

That's an interesting talk. It leaves me a confused about s2ram though, given that it's presented as the state of the art, but yet the s2ram user interface binary has been compiled out of the recent Ubuntu uswsusp packages. Maybe pm-utils replicates the same userspace functionality, but with the HAL whitelist instead of the s2ram whitelist??

But then neither uswsusp or pm-utils packages are installed by default it Gutsy ... why's that?

Since the main problem is closed drivers for Video cards, it's the choice you have to make at the moment.

Use open source drivers (with minimal/bare 3D accel, think old ATi cards, intel cards etc) and have suspend/hibernate working pretty much fine, but expect slow 3D performance (on my 9600 mobile the open source drivers work well enough for wobbly windows etc, but obviously can't do heavy 3D). Or use closed source drivers, but don't expect suspend/hibernate to work. It's a choice atm you'll have to make.

You cannot blame ubuntu for this, it's driver makers fault. Some are doing there best (intel for example) some are changing their old ways (ATi). And as mentioned before, even windows has plenty of problems with suspend/hibernate. Though I absolutely agree, Suspend/hibernate is very important to us all.

I installed Hardy on my HP Compaq 8510p and was pleased to see that suspend works with the radeonhd driver. However sometimes it still crashes, I think this is maybe related to the radeonhd driver which is developed by Ubuntu.

But if it does not work correct, Ubuntu needs to care about it. Otherwise users will run away from Ubuntu. I don't know where exactly the problem is, but maybe the Ubuntu developers need to collaborate more with Novell and the radeonhd developers (radeonhd is sponsored by Novell, afaik)

"
If suspend and hibernate were working, then we wouldn't need to worry so much about boot times. "

But then, if (re)boot was made faster then we wouldn't need to worry about suspend and hibernate either.

From the devs' point of view it looks like working on speeding those up is more viable than hoping for everyone to use hardware with open source 3d graphics cards.

As of your clarification about proprietary drivers, I stand corrected.

You mean, like in no OS? Even windows doesn't offer that out of the box and has issues.

Buy one that doesn't require that sort of driver.

"Using my graphic adapter to its full potential is the main reason why I did b*u*y a graphic adapter, so it should not be a reason for not having the possibility to suspend and resume."

You are just saying it is not a valid reason because you don't agree with it.

As long as the kernel devs work in compiz, this statement is relevant, else it isn't.

Ubuntu does allow you to turn the computer off.


"This is for me the most anoying bug that there is in ubuntu. "

That's a matter of opinion.

eythian wrote on the 24 Mar 08 at 12:04
vexorian: suspend is useful. I use it on my laptop all the time (where suspend and hibernate work just fine). It saves more power than being turned on (in suspend, batteries will last about 1.5 days), and is much faster. I can close the lid, pull the power, and by the time I've put the laptop in my bag, it's asleep. Open it up, and 3 seconds later it's woken up. It's incredibly handy. I'll use hibernate if it's going to be a while before I use it next, but 99% of the time it's not on, it's in suspend. Hibernate is too slow to be practical for people doing things like going between classes, moving 2Gb between RAM and disk just isn't a fast operation, and you have to be careful when it's doing that or you risk damaging the disk.

My point is, just because you don't think it useful, doesn't mean others shouldn't use it.

aidave wrote on the 26 Mar 08 at 18:05
No I complete disagree vexorian. Suspend/Resume is not about saving power. Maybe it is to some people... who knows.

The point is being able to turn your laptop off and on quickly. NO ONE in everyday life of a laptop thinks "Hey I want to wait 5 minutes between on/off every time to save a teeny bit of power". Thats simply absurd. Someone forgot to add that last line to their resume, or whatever, they need to quickly open/close their laptop to do quick things.

Fact is people will not use Ubuntu if it cant handle a basic task like suspend/resume. I have seen the frustration first hand and I'm willing to bet Ubuntu has lost countless users to this unfortunate messup. Windows provides suspend/resume, so they return to what works.

vexorian wrote on the 27 Mar 08 at 15:36
Yeah well, I doubt those users matter that much, if they leave at the first moment of unfamiliarity they will eventually leave for another reason anyways.


I insist, speed up boot and reboot, imagine if it took 15 seconds to do either of them (which seems possible since right now it is taking 45 seconds) , for the very same reason you have stated you like to use suspend, you would be able to power off the computer that fast. And it will save energy as well.

So, after reading your statement, I would say that if boot/reboot took much less time, you would agree with the idea of removing suspend and hibernate, and that's what I am saying, since , according to the devs it is currently unfixable, the best approach would be to begin working on improving boot/shutdown times to make them a viable alternative to suspend and hibernate.

With my desktop at work running windows, I suspend it at the end of each day, and each morning it wakes up within a couple of seconds, with applications already running where I left off the day before. even a 10 second boot isn't getting close to that convenience.

If we can get full boot, including gnome desktop, and sessions started plus files loaded for emacs, firefox, and Matlab all within 5 seconds, then I'd say there's no need for suspend.

I agree that hibernate isn't such a big thing to get excited over though.

The real problem with suspend and hibernate is that its hard to discover whether its going to work on particular hardware or not. Results are often anecdotal and in reports it isn't clear which methods were tried or whether there are other ways of getting it working.

Couple with that the fact that its a moving target, and for me for a given piece of hardware, it has generally gone backwards. My old laptop used to suspend fine all the time a few years ago, but then around dapper or so it stopped. Then my desktop used to suspend reliably, until a kernel update that shipped somewhere in fiesty .. and since then I've never been able to get it to do it.

The problem that Ubuntu can address is getting the right information more readily available, rather than relying on hunting through out-of-date forum posts to find out (a) whether some hardware works, and (b) the right methods to try in order to get it working.

Ok, well should a consumer trust a computer preinstalled with Ubuntu to work properly? Some people seem to think not, if you buy a laptop from Dell for example, and suspend/resume doesnt work, somehow that is the fault of the consumer for not doing research. Come on...

Also, to say that Ubuntu should get rid of suspend/resume and replace it with a quicker reboot, is not solving the problem, but trying to cover it up. The fact is that Suspend/Resume is a fundamental feature of laptops.

jblackhall wrote on the 14 Apr 08 at 01:02
That was a ridiculous article. Have you read any of the responses in this thread or in the comments to that post? The fact remains that if suspend and hibernate are not working on your machine, it is almost always due to proprietary information (from companies like nVidia) being unavailable to Ubuntu developers. If they will not share accurate specifications on their video cards (so devs can create open-source drivers) or provide bug-free proprietary drivers (not likely), there is NOT A WHOLE LOT UBUNTU DEVELOPERS CAN DO, "show-stopper" or not. Got a problem with it? Get a graphics card that has open specifications (like Intel's do) or START GETTING PISSED OFF AT NVIDIA, NOT UBUNTU. As it is, the open-source drivers are trying to reverse-engineer the video card drivers. That's never going to work very well.

It's also very annoying to hear people insist that things work fine on Windows, therefore Windows is doing a better job. That's complete BS. Even if nVidia cards suspend/resume perfectly in Windows (a very debatable point), that says nothing about Windows. Any reason it's working on Windows is because nVidia made their proprietary drivers work right specifically for Windows, but they didn't take the time or effort to do the same for Linux AND they won't make their specifications available so that we can do it ourselves.

johno wrote on the 14 Apr 08 at 02:28
This is not just about the proprietary drivers. Even on fully open hardware there are problems that don't need to be there. With even Intel graphics, I've found cases where suspend stops working after updates or upgrades to new versions. These are kernel level and driver problems. A lot of kernel and driver development seems to go on without regard to suspend/hibernate, and it only considered as an afterthought. This could be considered a shortcoming of Ubuntu in trying to use a server-oriented OS in a desktop market.

There are also problems in the packaging and configuration of the available suspend tools. I found my laptop started suspending successfully after installing an additional package. I only knew to look for that package after seeing it mentioned in an obscure reply to a obscure post in an obscure forum somewhere.

Then there's documentation - It's hard to get authoritative current information about the way it's supposed to be done and what alternatives can be tried. Even for people willing to debug different hardware, its hard to find where to start. Doing a search on ubuntu suspend yields a whole lot of older pages with various attempts and anecdotes, many of which are outdated and don't represent the "right" way of doing things now - and also apply only for some unknown types of hardware

Then also yes, it does make sense to compare to Windows. If Windows will suspend and Ubuntu won't then Windows (as an operating system) is doing a better job in that aspect. Sure, it may be harder for Ubuntu to do it due to its development model and popularity, but that doesn't change the facts about which is actually working better for the user.

I voted for this issue a bit too fast, cause right after voting I saw that:
"even with proprietary drivers."

Sorry but this is not the solution. Work is being done upstream with free software (the kernel, HAL,...), why would we want to short-circuit them and despise their work by using proprietary drivers when we could work with them and help them fix this issue only with free software ?

johno wrote on the 15 Apr 08 at 12:07
The "proprietary drivers" remark means getting suspend+hibernate to work through open source code, but even when using the Nvidia or ATI proprietary video drivers. It's relevant because the presence of those drivers on a user's system is often taken as an excuse for why suspend shouldn't be expected to work.

So it isn't about short-circuiting the open-source developers. At worst, its making life harder for them by getting them to test against systems with binary video drivers installed. Perhaps there's also some pressure there to get more dialogue going on with the video card companies to get their driver bugs with suspend sorted out.

That makes a lot more sense :)

The only problem with that is that it will be kind of difficult to ask the devs of "suspend / resume" to support those binary drivers.

In fact with FOS drivers, the devs of "suspend / resume" can say "hey, your driver is broken so suspend / resume won't work. You should fix it this way, here is a beginning of a patch. Thanks in advance for fixing it."

With binary drivers, those same devs have the choice between:
1. "We do all the work to try and make those binary work, without even knowing how they work, without knowing if their next release won't break all that we did."
2. "Suspend / resume won't work with those drivers"

I kinda understand them... :-\

Oh, and we all know that it soon won't be a problem as every graphic card vendor will open its specifications and so free drivers will appear (look at Intel, AMD, VIA). :)

Suspend and Hibernate are the *most* important features for mobile computing, I really hope that Ubuntu team can pay a serious attention to these issues and play a key role to improve the situation, either by collaborating with the manufactures, or developing their own robust ACPI support. Wish these painful experiences with suspend/hibernate go away, forever.

There was a change in a kernel memory allocator that exposed a bug in the binary ATI driver - which to my knowledge ATI still haven't fixed. Then around the same era IIRC there was a change to a different Intel driver which seemed less suspend-friendly.

It's hard for Ubuntu to do much about those sort of issues, but where they can help as packagers is to make the most of what code and options are available, and harness the power of their userbase for debugging and dissemination of up-to-date methods for getting it working.

But nowhere is there suitable up-to-date documentation to say what tests should be tried to work out what configuration is needed.

Also, by claiming "linux for human beings" Ubuntu has set a standard for itself that is "slightly" higher than that of other distros, and I can very well say no to fancy Compiz effects if I get a linux I can finally switch to for it. I have waited many Ubuntu releases already, and I still can't dump my XP because of this issue....

Most of that is adding support for freezing fuse filesystems, exporting swsusp functions so we can use them and adding an improved (finer grained) method of freeing memory.

TuxOnIce generally applies cleanly (or at worst with minor rejects) against Ubuntu kernels. Git trees with it already applied to Feisty, Gutsy and Hardy are available from kernel.ubuntu.com.

That said, I agree that I should be seeking to get it merged into vanilla. Unfortunately I don't have a lot of time to work on that now, and it seems that too many people have swallowed FUD to even consider it anyway.

This is what worked for me. I am usinga Toshiba Portege M200 with an Nvidia GeForce FX 5200 display. For me, Suspend/Hibernate would work, but it would not resume properly. I did some research on the Internet and I figured out that I needed to edit /etc/acpi-support in gedit. So I went into Terminal and entered in "sudo gedit /etc/apci-support". Ubuntu opened up a gedit window with acpi-support in it. I then changed the type of suspend to the other type (not the default.) I tried suspend again and voila! It worked! If somebody knows a fix for hibernation, please post it.

Personally I agree with those who say we should just scrap suspend and speed the hell up out of boot and reboot. If someone wonders why there isn't a suspend, we'll be able to tell them turning the computer off or hibernating (hibernating will still be there in order to keep a session)is just as fast as suspending on another OS, then it will be even better because guess what it does:

1) It reduces complication to the user, which increases work efficiency and makes computing a pleasure for the user

2) It saves EVEN MORE power because now ABSOLUTELY NO power is used when the computer is off. Sure, it takes power to turn on the computer, but first we can make boot up extremely fast and also make it power-efficient or even have an energy-saver boot up style in the power options that should be coming in a future release of Ubuntu.


To reiterate, scrap suspend, speed up boot and shutdown, and make hibernate really good.

johno wrote on the 14 Jun 08 at 05:52
One of my desktops suspends ok with Ubuntu (athlon XP with ATI 9200se video), and the power draw is:
On: 68W
S3 Suspend: 3.3W
Off: 3.1W

So the power needed for S3 suspend is negligable compared to the power supply leakage current. For modern computers, the only way to get absolutely no power draw is to pull the power plug out, and most people don't do that.

I don't see how having to re-start applications and find context again increases work efficiency and makes computing a pleasure for the user.

S3 Suspend is just expected to be available these days, and is strongly demanded. Having it working poorly in Ubuntu is an embarrassment, and the lack of debugging documentation is a shame.

Cutting corners has never been a way to become a leader of the distro.
Suspend and hibernate MUST ABSOLUTELY work. On my system it does not since one year and an half !!!
It does not matter who's fault it is. I used to have MS W and it worked, now with Ubuntu it does NOT work.
The final word is the quality of the service rendered to the users.
Ubuntu (and other Linux distro) is failing miserably on that topic, and as an old software GM, my answer is always the same, the developers (we) are not good enough, sorry guys...
But this poor performance is costing us 2 Nuclear Reactors of 1.000 MWatt/h each per year....On the other hand, I thrown away my Win and I am ecstatic about Ubuntu in general.

Suspend is still useful for laptops, is faster if they just close the lid and it suspends, a few mins later the user open it again and in second everything is how it was left.

The time requiered to suspend is the catch.

I recently switched back to an old Dell Inspiron 5100, temporarily.

Admittedly it's old, but it's really common, suspend/hibernate should work for it. I reverted to the 7.10 kernel, which has both suspend and hibernate support for it.

Even my 2 year old custom built system that has always worked with suspend (never tried hibernate on it) Does not work with 8.04 now. I guess I'll have to try reverting it's kernel as well.

But this sad... why exactly is the ability of Ubuntu to suspend/resume getting WORSE instead of better?

Neither one works with with or without using proprietary drivers.

this is one of the reasons why I think Brainstorm is to a large part busy-therapy for complaining whiners like us users. We spend hours voting for cool ideas, lament the bugs that prevent it from really being "for human beings", but at the end of the day, no matter how many votes this gets, it is not the metaphorical bullet to the programmer's head. But I agree with most of what's been said above, this "idea" should really be marked as "in development", and since it isn't, I have a BAD feeling about Intrepid

@FrancoNero: This isn't even an idea!

Post ideas on how to fix this Suspend and Hibernate problem and I will be glad to vote for them.

This "idea" (problem) should be marked as "not an idea" before everyone starts posting their pet peeves and not including ideas to solve their pet peeves.

We are looking for ideas to solve the Suspend and Hibernate problems. Does anyone have any ideas on how to solve that?

Here's few:

1. Provide an experimental kernel with the debugging features enabled and the latest suspend and hibernate patches to make it easier for mass testing.
2. Patch Apport to mark the bug reports that a certain application crashed after a suspend or hibernate.
3. Create a wiki that list known working and non working suspend and hibernate hardware.
4. If we need hardware specs, petition the manufacturer.
5. If the bugs have been identified and no one is working on them, create a bounty.

These are just at the top of my head and that is what we should be voting on as well.

yes flammon, I agree that it is not an "idea", but I am not a programmer, so I certainly don't have a "real" idea on how to fix it, other than saying the big idea is to fix this somehow, if you consider the amount of votes this almost "non idea" gets, it should be telling how urgent and important this "issue" is to users/people.... let's call them Human Beings, after all that's what Ubuntu claims to be, and the sort of human being I know, wants to hibernate, or at least suspend his or her laptop without suspecting alien activity going on while witnessing all the weird stuff that's visible on the screen while trying....

I'd go as far and say every other issue/feature out there for intrepid isn't even half as important as this one..... maybe the Ubuntu makers, and I applaud them because I really like Ubuntu a lot and so much is happening, really, aside from my ranting, Ubuntu is really great, but maybe the Ubuntu makers don't suspend/hibernate enough to see how broken this is on many laptops? just an assumption. or people involved in making Ubuntu pick an Ubuntu-compatible laptop in the first place?

Yes fixing Suspend and Hibernate is critical.
In my PC, Suspend is OK, though a little slow but acceptable but works most of the time but Hibernate does NOT work half the time.
Fixing Suspend and Hibernate should be of topmost priority.

Wouldn't it be possible to blackmail Nvidia, in order to get them release an open source driver?

Mrcurry, Nvidia don't need us, we need them. They have done a lot for us, and supported us well from their beginning.

And if we go around blackmailing companies, they sure wont help us... And I guarantee many linux users would leave.

And I frankly find the suggestion semi offensive. We shouldn't associate linux with blackmail

These things don't work for me either, on either laptop I have at home (one P3 and one P-m based, both Ati graphics). This isn't a showstopper for me but it does suck, and I can completely understand it is a showstopper for others. I fully understand how Canonical cannot just fix this as there are too many external dependencies: the kernel devs and Ati/AMD and Nvidia. However, this IS your operating system which does present this reasonably serious flaw so I hope you'll try your best to put a little pressure where necessary to have this fixed. It's not your fault but it doesn't make Ubuntu look very good and that isn't beneficial to anyone (well, except for Microsoft maybe).

gutnov wrote on the 14 Jul 08 at 22:28
I would disagree with Auzy that Nvidia don't need us. 6 months ago I had a choice between Acer laptop with Nvidia and Fujitsu-Siemens with Intel. Finally I bought the second one and now have Suspend function working! I do not really need Nvidia...

Alexander wrote on the 16 Jul 08 at 12:47
Resetting the BIOS to default settings fixed all issues on my computer.

Auzy wrote on the 16 Jul 08 at 13:39
Well, Gutnov, if an integrated chipset like intel was good enough for you anyway, you would have gone for it probably more because of price (they are horribly slow). But. what you need to understand Gutnov, is that Nvidia changed everything for us. They didn't have to offer any linux drivers from the beginning (lets face it, we would have come up with our own, and at the time, linux has no penetration whatsoever).

Except, the drivers at the time we produced wouldn't have been as good... Not nearly as good. And their drivers showed many users they were serious about linux. And in turn, those drivers were used to prove to users, that Linux was good, which spurred a whole new segment of development.

If the nvidia drivers are causing problems, it may be a result of too much competition actually. Both ATI and Nvidia have to sacrifice some stability in the drivers department for much better optimisation of drivers (like doing dodgy clipping in benchmarks or lowering graphics quality). The best thing we could do is improve the bug reporting systems, so that we can report back exact systems that don't suspend/hibernate properly, so we can isolate which hardware configurations have issues so they can fix it (this would be the case normally anyway!)

Like it or not, consistent driver support from Nvidia is a beating pulse in our Linux timeline, and we should respect the effort they put in. Whilst something we coded might be a bit more stable, they probably wouldn't have been near as fast as Nvidia's official drivers.

But anyway, due to the changing environment (AMD swallowed ATI), this might change soon anyway. After all, Nvidia's purchase of 3DFX, probably contributed significantly towards their fight with ATI for so long.

+1 I've never had any luck with any kind power saving on any os.

@ rorymccann, purpleidea, gcc and others
So "free software" should not allow me to choose proprietary drivers over open source and have them work? Doesn't sound so "free" to me. I reserve the right to choose which ever drivers I want to use, not you or anyone else. This is freedom of choice.

Anyway that's not what this is about. Its about the problems lots of people are having with suspend and hibernate irrespective of what being used to drive it.

The Ubuntu developers can't do much about proprietary drivers which are the responsibility of the driver developer, but they can assist where possible.

baruch60610 wrote on the 24 Aug 08 at 11:56
I'm not sure this is a Linux problem. I've never had hibernate or suspend work, in any computer, not even with the original OS (usually a flavor of Windows). I've long since just given up on these "features", assumed they weren't available, and managed to get by without them.

Sure, it would be nice to have them, but... if Ubuntu manages to make them work, they've boldly gone where no (wo)man has gone before... +1

nogasbiker wrote on the 1 Sep 08 at 22:33
Just to offer a counterpoint to those that say they haven't seen suspend / hibernate work properly...

I routinely see suspend and hibernate work properly around here, on various flavors of Windoze and Linux.

In fact, the only os I cannot get hibernate to work right is on Hardy using a Dell Latitude D610. I seem to be in good company, as there is no shortage of hibernate threads for Hardy. Actually, it appears to hibernate correctly, it just cannot resume from the image and merely reboots.

withfries2 wrote on the 3 Sep 08 at 05:03
Strangely, standby/resume works fine on my laptop (Dell Latitude D420) but not at all on my desktop (Dell Dimension 8400). I've tried a few of the configuration file tricks as recommended by the forums, but no dice on the desktop -- get the blank screen every time I try to resume.

Getting it to work reliably would be fantastic. Booting takes to long, and leaving it on is just not an environmentally friendly solution when these computers have these nice low power standby modes which work fine with Windows.

I'm fairly new to open source but love the idea and the feeling I've gotten for the Ubuntu project is a good one, but I've had a few hardware problems besides this, though this one is driving me crazy! I'm an IT student at Uni and I can't even get this fixed on my Desk top, yet alone laptop. My desk top is 64 bit AMD based MSI motherboard with NVIDIA PCIe graphics card. All that seems to happen when I suspend is an improper shutdown, and I have to restart as if I've just had a power cut! I do love Ubuntu, but I hope this is sorted soon (especially considering I just had to dump my xfi soundblaster extreme audio PCIe card for a more lowly model so as to have a working duel boot system - dedication, hey?)! I also so think it would be in Ubuntus interests to have a listing dedicated to informing users about confirmed hardware compatibility.

Auzy wrote on the 13 Sep 08 at 00:04
We should actually get a Safe Suspend mode too (which keeps everything in ram still, but also backs it up to the HDD, so if the power runs out, it takes longer to restart, but at least then you never lose any data).

this is on a new pc wich as a asus m2n-e motherboard and a asus nvidia 8600gt vid card using the proprietary drivers.

i am very surprised at that successfull result and even more that i did not even need to do anything to be able to achieve it.

I used to have this problem consistently with Feisty and Gutsy, intermittently with Hardy, but I tested Intrepid and it was perfect. I am on an older, less popular laptop (Dell Precision M20) but this is a godsend. Personally, I think it was the open sourced from proprietary ATI Drivers. That's what I was told was stopping Suspend and now it works and they're OpenSource.

WOW... just WOW, NVIDIA USERS REJOICE

I just changed 3 lines in 2 config files, and my suspend works for the first time ever on this PC!!

I have been annoyed ever since I bought this motherboard 5 years ago...

I just thought my motherboard was buggy and didn't support suspend...

Stumbled across bug 34043 and the https://help.ubuntu.com/community/NvidiaLaptopBinaryDriverSuspend pages...

So I thought... what the hell, suspend would be nice, lets give it another go!

My setup is Hardy 8.04.1 with updates and backports and proposed and several PPAs and envy-ng with nvidia drivers: 173.14.12
Abit NF7-S mobo (NForce 2 Ultra)
Geforce 5900XT AGP
Never suspended correctly before in Windows XP

So I set the option in xorg.conf in Section "Device"
Option "NvAGP" "1"

And I changed the 2 options in /etc/default/acpi-support
SAVE_VBE_STATE=false
POST_VIDEO=false

AND guess what!! it F@#$#@king works for the first time ever!!! I'm so happy I could cry!!

Previously it would sleep ok.. then it would just beep continously with a blank screen until reset when you tried to wake up.

Any disadvantage to NvAGP "1" I should know?
If not, this should seriously be the default!

Thanks to all the hackers that discovered this!

Note about my previous post...

Option "NvAGP" "1"
was trying to load the NvAGP part of the nvidia driver, and failing, falling back to PCI mode, which made it equivalent to Option "NvAGP" "0" which I'm using now... it's a bit slower then actually having AGP support, but suspend is better then no suspend, I save so much time booting it's worth it... especially since the nvidia driver is so slow in 2D acceleration anyway.

I love Ubuntu and have installed it on at least eight different computers, from netbook to desktop to mini-server, from brand new to slightly dated to really old, mostly without any serious hardware problems. BUT not on a single one of these machines does suspend/hibernate really work, i.e., work consistently and reliably each and every time.

Some of my machines won't suspend at all, some will just freeze when trying to wake up, and the remainder will lose at least some essential functionality after waking up, like Bluetooth, the touchpad, the keyboard, display backlight, or two or more of these in varying combinations.

Please do something about this and make suspend/hibernate one more area where Ubuntu is far superior to Windows!

Fixing suspend is not just for laptops. Broken suspend on Linux wastes power and costs users.

Unfortunately it's broken in many ways- permissions, drivers, poorly written acpi, etc. It works fine for example on my laptop running Xubuntu, by my desktop will just return me to the GDM login screen. Why? I have no idea.

We need better tools to understand why suspend does not work, and how to fix it.

PowerTOP for suspend would be nice.

I don't know "why" this works, but it does for my Thinkpad X60s. I suspect its something that will work for others, since its a bios level thing, and that relates to the previous post.

1. sudo gedit /boot/grub/menu.lst
2. find the grub menu line that is the ubuntu default .. the first one that appears, that will look like this:
title Ubuntu 7.10, kernel 2.6.22-14-generic
root (hd0,0)
kernel ....... etc

3. Add the following to the end of the "kernel" line:

acpi_sleep s3_bios

Here is my "kernel" line.
kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=b6e33b4a-d2ec-4107-9aaa-8956ed669d82 ro quiet splash acpi_sleep s3_bios
