People forget to empty their trash and get problems with space

Written by sucotronic the 18 Feb 09 at 17:00. Global category: Accessibility. New

I've observed in my job that most of the users forgets to empty their trashes regularly, and suddenly one day they start to have problems due space limitations, or they don't know where is used their hard drive space.

Solution #6: Don't put unnessecary distractions in the system!

Written by kapipi the 21 Feb 09 at 21:17.

This solution is a response to solution #1. Solution #1 is great, except that as a default the user should not be notified about the size of trash, unless space on the partition is getting critically low.

The rationale:

- We don't want to distract the user's attention unnecessarily
- We don't want to force or lure the user to empty his trash unnecessarily.

Solution #11: Use the desktop icon to provide information

Written by Menti the 7 Mar 09 at 12:23.

As proposed in idea #14699. Desktop icons in general are static and do not provide any useful information. Trashcan icon is slightly dinamic: it has an empty state and a full state. Let the icon change to show how much trash there is. There could be a (configurable, with a sane default) max limit to the trash size, and the desktop icon could show what percentage of that limit is already in use.

This way, we could have more information without actually adding anything to the current setup, no more clutter; only better use of an already existing and underused graphic element of the desktop.

Solution #12: Put the trash icon on the desktop

Written by dubrict the 10 Mar 09 at 06:19.

The reason people forget is because by default, the trash icon is as tiny as can be and hiding in the corner. Placing it on the desktop instead puts it more directly in the user's conscious, reminding them to empty it while not being obtrusive or complex.

The "running low on free space" reminder is reasonable, because it would solve this problem while taking on another. There's no reason to add any complexity to the system beyond this.

Solution #15: Beyond Icons

Written by trustno1uk the 16 Mar 09 at 20:02.

Icons that represent valuable information at first glance can really save you some time.

Some users don’t care about emptying their thrash and also use it as another folder at times, this will remind them to empty it.

Solution #16: Automatically delete after 30 days

Written by OrelEagle the 5 Dec 09 at 20:38.

I'm using a script to delete files permanently after 30 days spent in the trash:

find ~/.local/share/Trash/files -maxdepth 1 -ctime +30 -exec rm -r \;
find ~/.local/share/Trash/info -maxdepth 1 -ctime +30 -exec rm -r \;

This way the user doesn't have to worry about emptying the trash but still has a "second chance" in case a file was deleted by mistake.

Solution #17: Provide a suite of tools for the user to save/recover disk space

Written by yoda2031 the 28 Mar 11 at 17:26.

Computer Janitor already fulfils the requirement to recover disk space from files which are temporary/cached/etc.

Squashfs more-or-less fulfils the requirement to conserve space, but should be provided as an option on installation ("compress home directory" and "compress system directory" options)

A utility to automatically compress/remove components which have not been used for more than 30 days.

A utility which lists your installed applications in order of size and last used date. Allows the user to remove the bigger, unused packages.

A utility which allows you to "reorganise" your partitioning scheme.

Where applicable, these solutions should be accessible under an umbrella utility, possibly as an extension to the existing Disk Utility, or as a stand-alone utility.

There's no unified way of reporting progress in Ubuntu

Written by amrhassan the 7 Mar 09 at 23:30. Global category: Look and Feel. New

Filesystem operations (copying, moving, deleting files and directories, etc...), importing music into a media player and so on should be displayed in a unified way all throughout the desktop environment.

Solution #1: Work progress reporting into the new notify-osd

Written by amrhassan the 7 Mar 09 at 23:30.

Like in this mockup:

Progress reporting can be done in a notify-osd bubble and have it always-shown along with the other maximum of two notification bubbles. This progress bubble can have other operations concatenated to it while it's on, so we don't have to need more than one extra bubble for all the progress reporting.

Solution #2: use the file-transfer's style

Written by yzarc the 8 Mar 09 at 23:16.

use the file-transfer's style. as it's already done by the nautilus on the file transfers, make possible to other programs to report its progress (and some controls) on this panel too.

in this case the icon should be replaced for a more generic one rather than the nautilus'. if possible a composed icon that indicates the global progress by a small pie or bar chart.

use notify-osd just to alert when one task is done.
I believe the look and feel of the nautilus progress panel will be improved to match the notify-osd level soon.

mockups below:

icon state
Photobucket

on mouse over state
Photobucket

windowed state. (after one mouse click)

Solution #7: A mix of #1 and #2

Written by Joshua Hesketh the 16 Apr 09 at 14:01.

Similar to how notifications disappear into the task bar, actions (or progresses) could disappear (/fly) into a process queue (rather than a message queue). This way a nice notify-osd message can come up when you commence copying a file (in a very un-obstructing way) and then it is still accessible through the detailed list. You could even have the action fly out to notify-osd upon completion.

Easy mounting of Images like ISO and CUE

Written by Nanotron the 28 Feb 08 at 20:17. Related project: Nautilus. Implemented

I'm a big fan of Images like .iso. However it is not very easy to mount these Images.

There is already right click->open with "archive mounter" in Gnome, however it currently has a major bug: https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/299956

Selected solution (#1): Auto-generated solution of idea #194

Written by Nanotron the 28 Feb 08 at 20:17.

I feel there should be a Tool in Nautilus and Dolphin which allows mounting Images by double Click or something similar. (This feature exists int MacOS). Or with a right click on the I think that would be a very useful Tool for every one.
A good example for this is CDemu.

I know there are some other good programs, but I think that would be the easiest way

Selected solution (#8): Okay, here it is :)

Written by r0g the 28 Oct 09 at 05:09.

In the form of a python script for nautilus actions.

http://www.technicalbloke.com/iso_mount.py

I don't have time to do the unmount command too but it should be easy to adapt if you know a little python, consider that homework & pls post me a copy :)

I think it would be nice if Ubuntu came with some more useful nautilus action scripts and a nicer way of adding/removing them. At the moment getting them in and out is more of a pain than it needs to be. It ought to be as easy as Firefox (if not easier!) to install plugins, maybe then people would make more.

No Mono by default in Ubuntu

Ubuntu

In :
Priority :	Undefined
Definition :	Review (Needs guidance)
Implementation :	Not started
Assignee :

Written by Ubuwu the 28 Feb 08 at 17:50. Global category: System. Implemented

Remove Mono and dependent applications from default Ubuntu Desktop CD. Mono occupies a significant amount of the valuable space on the live cd that could be used for translations and other things. Applications using mono use much more memory than their non-mono counterparts. Functionality can be provided by other applications that are just as good.

This will NOT remove Mono or any of the applications from the Ubuntu repositories, just the default Desktop CD. (Although removing them from the CD may mean they don't need to be in Main anymore)

This affects two applications included by default: tomboy and f-spot. Tomboy can be replaced by either sticky notes or zim and f-spot by gthumb.

Selected solution (#4): Promote Vala as a Gnome enviroment programming language

Written by diegoj the 25 Jun 09 at 21:27.

Vala is a modern language for programming in the Gnome desktop enviroment.

Its code is compiled to C and this is compiled to machine code.

Vala has got all the features that C# has, thus Vala doesn't rely on a virtual machine and isn't patented by anybody like many parts of the Mono machine (Winforms library, for example).

Promote its development and the development of applications based in Vala compiler (like Lucruri) and stop wasting resources in Mono-based projects.

Selected solution (#5): Replace Mono-based applications with Mono-free ones

Written by diegoj the 25 Jun 09 at 21:47.

Replace every Mono applications with its direct C++ port (or similar). That is:

- Tomboy must be replaced with Gnote.
- F-spot must be replaced with Solang.
- Banshee must NOT replace Rythmbox.

Why should Canonical do that? It will...
- Avoid patent demands. Winforms library is patented by Microsoft.
- Make Ubuntu applications faster. Mono is slower than machine code.
- Save live CD space.

Selected solution (#6): Shotwell instead of F-spot

Written by jeypeyy the 25 Dec 09 at 00:15.

Same as Solution #5, but instead of using solang as a replacement for F-spot we should use Shotwell. Shotwell is an application written in Vala, the language Solution #4 wants to promote.

It's better than Solang because you can remove red eyes. Since it's written in Vala it's easy developing for GNOME, which means the development probably will be faster than for other applications.

Power Management

Ubuntu

In :
Priority :	Low
Definition :	Pending Approval (Needs guidance)
Implementation :	Slow progress
Assignee :	Amit Kucheria

Written by jsmidt the 28 Feb 08 at 16:49. Global category: Others. In development

Ubuntu needs to go green. Powertop, Lesswatts and other tools have finally hit the Linux scene to pave the way for better power management. It needs to be said, "if you want your battery to last longest, or have your energy bill be the lowest, you better use Ubuntu Linux."

Merged from 18976:
Power management still isn't very effective in Linux and it still puts a lot of laptop users off Linux. While Linux has come on a long way thanks to the work of Intel with PowerTOP informing developers when their software breaks the idol state unnecessarily so they are doing their part as well as the kernel developers now we still have a long way to go to compete with Windows and I'm looking at ways for Ubuntu to do this.

One of the benefits of Linux is that is very easy to customise and a lot of its users love to tinker. Ubuntu should therefore use this to its advantage by allowing its power users to easily have access to the latest developments in Linux power efficiency. This would also be useful to Ubuntu as power users could submit results on what settings are most economical for specific hardware. This would give Ubuntu the chance to market itself on its power efficacy over other operating systems by it silently implementing these settings on the detected hardware setup for new users.

To give users these advantages Ubuntu should help more on Intels Lesswatts projects as these are Linux's best bet on beating windows power management. The problem is the solution to effective power management needs to simple enough that it works for a new user that wont even know its active but also very easy for power users to modify and test their own setups from one central tool.

Selected solution (#6): Develop/Intergrate WattOSPM (GUI laptop-mode/Powersaving) in2 Gnome-power-manger

Written by chappell101 the 1 Apr 09 at 15:16.

This is taking Solution #3 to prevent conflict and expanding to give Gnome-power-manger 2 modes, simple for average user and button to reveal an advance set of options for power users based off the options in WattOSPM and PowerTOP.

To stop average users completely breaking their system with the tool only include safe things to disable in the simple mode in an on/off switch manor such as the optical drives and sound chipsets which aren't necessary to all users on the go but still waste power, Also this is a feature possible in windows for a long time now! The advanced mode could log user results of all their changes and show on a graph similar to Gnomes current power chart and have the option to submit the best back to Ubuntu so they can be set as silent defaults values for specific hardware for less technical users.

WattOSPM is already an effective little python tray-bound GUI to enable fast changing of laptop-mode-tools, X-backlight, and Powersaving settings to optimise many parts of your system for battery consumption and performance. So it would be nice to see it assisted by Ubuntu developers to add more features while it is integrated into Gnome to give back to the whole Linux community. These changes could be those found in Rightmark CPU Clock Utility for Windows Eg.CPU performance states editor, Thermal throttling values, and CPU PLL lock time these could be accessed through the Gnome CPU Frequency Scaling Monitor applet in the tray if cpufreq-selector is installed by default.

[...]

Also get Ubuntu to look at some of the power/speed measures used in the Ubuntu derivative distribution WattOS and port them back to the main distribution where possible.

Selected solution (#7): Write a simple GUI to control laptop-mode-tools.

Written by andrew.p the 19 Mar 09 at 22:03.

Here are some parameters of /etc/laptop-mode/laptop-mode.conf that sometimes should be customized not only by greatly experienced users: readahead size, disk spin down timeout, maximum time to keep data in memory, low battery level to write data to disk, whether to enable all of this on AC power. There IS a reason for it, for example optimal readahead can be very different on machines with different amount of RAM. Also, this is a way of locking some values (for example the tool should not allow to set readahead >RAM/50).
Also there should be a global Enable HDD Powersave Tools checkbox controlling /etc/default/acpi-support ENABLE_LAPTOP_MODE.

And I also think there should be an option (with warning) to set hdparm -B to 254 in all modes (this fixes ustoppable spinning down on battery for some laptops).

Selected solution (#9): Expand the capabilities of gnome-power-manager

Written by brand0con the 12 Mar 09 at 01:27.

Gnome power manager is a great tool but I think it could use some expansion. Namely, I'd like to see it logging (and eventually graphing) the system's battery history over the long term (not just a session) to give a more accurate picture of how a user typically uses his or her machine battery-wise and to give a sense of the machine's capabilities.

Ideally, the app would mature and after a set interval of recording this data, it would be able to provide a few basic suggestions based on power related events as to how the user can get the most life out of their battery in the long and short term.

Selected solution (#10): "Green Software" Logo

Written by MX the 27 Mar 09 at 12:44.

To increase visibility and to be supported by facts: e.g. increases battery life by x% on average (for notebooks) or reduces average energy consumption by x % (for Pc's).

From my experience proper, non-technical and business oriented communication is key to reach most users and convince them about the usp's of a product.

Thinking of a usp - energy efficiency has a high impact.

Appreciate your thoughts and keep going!

Selected solution (#12): Automatic charge/discharge

Written by Mondane the 9 Feb 09 at 14:26.

The user shouldn't be bothered checking his battery and/or removing the battery when on AC power. Make the OS drain the battery on intervals so the battery stays intelligent when the laptop is on AC power.

The user should have the option the interrupt and revert the draining if he knows he needs a full battery and is leaving in a short time.

Selected solution (#13): Set the maximum battery charge on AC power

Written by mathieu the 5 Feb 09 at 18:36.

In order to preserve its battery's life, I would like to set the maximum percentage of charge (60% or 80% for example) when I'm not using it outdoor.

But if I have to use it outdoor, I want to release the limitation easily to get the maximum charge.
Finally, when I come back at home, I would like to use the battery power if the charge level is over the limitation setting, even if I have plugged the AC cable.

This trick will increase our Li-ion battery lifetime. Because if it is always completely charged when the laptop is running on AC power, its charging/discharging capacity will decrease quickly than if it is set on a lower value.

OCR

Written by grashdur the 28 Feb 08 at 19:58. Global category: Office. Won't implement

I love the fact that I can plug into my already-existing scanner and start scanning. What I don't like is the lack of OCR capability to convert text images to text data. From the support forums I understand that there are OCR possibilities out there on the internet, but for someone who is not a programmer, they are not usable at all.
(Also, for whatever reason, the XSane program is no longer working since my upgrade to Feisty Fawn.)

To set the scanning preferences press ctrl+p and set the starting page number, Mode of page numbering, double page mode if you intend to keep 2 pages at a time, rotation to select the way in which you want the program to rotate the images before conversion. In full automatic rotation mode, one can keep the book in 00 90 180 and 270 degree angle. In partial rotation mode program will scan once to find out the position of the book and then the rotation will be kept. In manual mode one should select the angle. partial and manual mode is faster than full auto rotation mode in ocr process. One can select the number of pages to be scanned at a stretch by setting number of pages in the case of repeated scanning. One can stop all scanning process by pressing ctrl f4.
2. Cam-scan.

one can now use Hovercam or a Webcam to produce text in LIOS. Adjustments with these devices can be made using LIOS-cam-preferences in edit menu. This feature will help to read books and other printed materials such as visiting cards currency and like and also it makes the ocr process very fast and accurate. Please be specific to use devices with auto focusing facility. remember that there is no autorotation in this utility.so for the same reason, support of a stand for the webcam will be highly appreciated.
3. Cam-reader.

is the utility which will give a continuous output as one moves the webcam. First it will create the image and then will produce the text and it will start reading. After the completion of reading, it will repeat the process automatically. In cam-scan, one has to take the photo and it will be converted in to text.
4. Ocr Image.

LIOS can convert image file to text which is in jpg, tif, png, pnm and bmp.
5. Ocr folder.

LIOS can convert scanned images from other sources. It can convert jpg, jpeg, tif, tiff png, pnm, formats. To convert the images in a folder, select scan from folder option from scan menu and then select the input folder.
6. Ocr Pdf file.

Select Ocr pdf from scan menu and then select the input file. It is recommended that one can use ocropus as engine more efficiently in pdf conversion.
7. scan for image only and scan for images only repeatedly.

Help one to scan only images and it will give the user opportunity to utilize different ocr engines conveniently. Also it avoids delay between each scan if one does not want to listen to the output. Images will be saved in LIOS or one can choose his own destination. Now conversion can be done using folder option.
8. Brightness checker.

To set a n exact value of brightness or threshold is the best way to ensure maximum efficiency out of ocr engines. To find out the best value, go to tools menu and select brightness checker. This utility will scan for 15 or 17 times to complete the process. After the process, number of words detected at different values will be shone in tabs. If

New users tell that Ubuntu is slow (live sessions)

Written by zwyber the 8 Mar 09 at 19:55. Related project: Live CD. Won't implement

I tell my friends and family about Ubuntu and most of them come back telling me that Ubuntu makes their PC run very slow. They didn't know that you had to install Ubuntu to get the true speed.

I think that many people may encounter this problem, because when you run a live session it really just looks like it is installed. Because of the speed these users don't want to use Ubuntu and tell everyone they know that it is very slow.

Solution #1: Show (extra) notification.

Written by zwyber the 8 Mar 09 at 19:55.

Very plain and simple, show a (extra) notification, telling the user that they are running in a live session and that Ubuntu runs very slow now.

Why extra? If Ubuntu developers are going to create a welcome screen where they put this information some people are not going to read this. Just a small dialogue after the welcome screen has been closed would be nice.

OR

Put the message in the default wallpaper, easier but not really the best solution.

Solution #13: Use UnionFS to our advantage

Written by deriamis the 4 Apr 09 at 18:40.

Since the majority of load times is in late-linking the libraries, why not have the often-used libraries in a ramdisk and use UnionFS to overlay those files on a path? In combination with pre-caching (#4), this could be a significant speed boost. If we combine it with using a LiveUSB distro (#11), we could be on par with the performance of the computer itself.

Solution #16: Instead of notification write it in the background.

Written by ll the 6 Apr 09 at 03:52.

A modified background that includes a warning can be used instead of a notification. Many computers at universities that are meant for multiple users use the background to communicate a special procedure especially in libraries for catalogue searches. This will decrease confusion and not use as many resources as a notification (I assume).

Solution #18: Calc & disp speed-up performance on log-out based on sys's characteristics

Written by lackscr8ivity the 7 Apr 09 at 14:25.

When running the live session I would guess the memory, processor, hard disk read/write speed (maybe not this one), etc. system hardware & performance are evaluated.
As well, when running a program (game, OpenOffice, etc.) the CD read/write & load time could stored. Thus, when the user ends the live session, in the log-out window list some statistics: "These are the 5 programs you used the most:
From the live CD it took X-amount of real-time to load, but based on your system's hardware, if this were installed, we would expect it would X% faster."

Solution #19: disabeling unnecessary services for the live-cd

Written by moose the 14 Apr 09 at 08:08.

So the live-cd shouldn't start services which are not neccessary for testing ubuntu (as some people use the live-cd as a secure system, services like cups are neccessary):

# anachron, atd, cron: I never used a live-cd longer than six hours - why should I create a cronjob?
# acpid, acpi-support, apmd, powernowd, powernowd.early: If I use the live-cd, I want to test if my hardware works and if the software fits my expections, not if the sleep option works.

Solution #24: Use the new notification system

Written by aroach31291 the 22 Oct 09 at 17:19.

Firstly, I think that many of the solutions above are solving the wrong problem. People that try out Ubuntu may think that it is installed by just inserting the CD. The user may have no idea that they are using a LiveCD. After they discover that Ubuntu is "slow", they give up and reboot back into Windows. Notifying the user that they haven't installed Ubuntu yet would be the best way to solve this problem.

Utilize the new notification system. Have it simply display a message when the desktop has finished loading similar to:

Ubuntu is not installed yet! Feel free to use Ubuntu before installing it, but beware that it may be a little slow. If you like what you see click the install icon on your desktop!

Solution #25: Show notification when system is waiting for CD drive

Written by mikko.rantalainen the 7 Oct 10 at 06:45.

Live session from USB/flash memory should be pretty okay even today but the real problem is accessing files from optical drive. Even there, the problem is latency, usually not the bandwidth.

The live session should run a small background service that displays a notification message when system is waiting for CD drive to access required data. The message could be along the line "Reading data from CD (installing on the hard drive would improve performance)" [however, the label should not claim to be reading CD if one is booting from e.g. usb memory stick]. The notification should be displayed if read command has waited in disk scheduler queue for more than a second.

This could be extended to deal with installed system, too. It would make sense to point out bottlenecks in the system to the user. If the system feels slow and a notification pops up that says "Waiting for disks (installing a fast SSD drive would improve performance)" would give a reasonable hint to the user which hardware upgrade would help the most. This could be even further extended and a similar notification should pop up if all CPU cores have been taken for more than 5 seconds ("Waiting for processor (upgrading the processor would improve performance)").

Graphical frontend to edit GRUB menu

Ubuntu

In :
Priority :	Undefined
Definition :	New (Needs guidance)
Implementation :	Unknown
Assignee :

Written by aysiu the 28 Feb 08 at 18:51. Global category: System. New

Right now, the most likely successful migrations to Ubuntu happen for *nix experts and total novices who have someone install Ubuntu for them, but the most likely people to try Ubuntu are Windows power users--those who like a lot of configuration options but who are also used to using the GUI for tweaking options and not manually editing a text configuration file.

The most popular requests for editing the /boot/grub/menu.lst file involve changing the default boot option (to Windows instead of Ubuntu) and changing the timeout before a boot option is selected. The other less popular ones would be just bonus features, I guess.

Solution #1: remove 'Brasero' software and replase in 'k3b'

Written by shimi810 the 3 Apr 09 at 01:56.

in Brasero - does not have a few bugs and is no longer functioning as functioning in the past;
in k3b - can burn really almost everything, and it is perfect for anyone (even though it is intended for users of desktop kde). Even the software automatically checks MD5.

Of course the intention is to replace the list of software packages that are installed automatically after installation in ubuntu.

Allow Guest to Log In from Login Screen

Written by rouge568 the 12 Jan 09 at 04:28. Global category: Security. Implemented

Allowing the guest to only log in from another user's account is, for lack of a better term, stupid. It means that if the owner is not going to be around when the guest uses the computer, he has to give the guest his username and password just so they can log and then switch to another account. This is an incredibly large security hole, that could be easily fixed. Please, if someone types 'guest' when logging in, take them straight to the guest account.
