I'm fortunate to have several systems. I've noticed that the standard generic kernels have one common feature amongst all the system's I've loaded it on. They run approximately 60% of full potential and even seems to fatigue on moderate system load.

One of the suggestions powertop (a tool that helps to save battery power) told me is to turn off my notebook's bluetooth when it is not being used.
"Disable the unused bluetooth interface with the following command:
hciconfig hci0 down; rmmod hci_usb"

I think it would be nice to have a way to turn off/on bluetooth graphically using bluetooth applet.

The USB devices connected can not be easily seen. For example, i would like to configure one pendrive to be mounted somerwhere, but other one should mount in other place, and I would like to see if (for example) a Bluetooth dongle is detected, etc.

Several hardware devices are using standardized hardware protocols. Linux supports these protocols and this hardware will thus work automatically.

However, when this device was very recently released by the hardware manufacturer, Linux will not know its name. Instead of showing the name of the device, it will use some general identification.

Example:
* "PTP2 camera detected" instead of "Canon CoolShot 450C detected"
* "USB Mass Storage device detected" instead of "Western Digital MyBook detected"

Disadvantages:
* Looks less polished
* Looks less professional
* Harder to understand for end users

Starting from Jaunty acpi-cpufreq is compiled in the kernel instead of a module, so to apply the phc patch (http://www.linux-phc.org/) we need to recompile the whole kernel.

A lot of people used to tune the processor voltage http://ubuntuforums.org/showthread.php?t=786402 and reported relevant benefits while maintaining rock solid stability, but having to recompile the kernel at each update is unpractical.

Multiple pointer devices, e.g. one touchpad and one mouse, might require different sensitivity settings.

If mice report their model to the computer (they do, right?), reasonable default settings could be kept in a database and mabye adjusted according to how the user has adjusted the settings of other devices. Any changes the user makes should of course be remembered until next time the same mouse gets plugged in.

With or without a database, a window could pop up the first time a particular model is plugged in, allowing the user to adjust the settings.

When can this be needed?

(paste from a duplicate idea)
Problem: I'm using a trackpad that I sometimes attach a USB mouse to, so I switch between using the trackpad and using the usb mouse, but when the movement and acceleration for the trackpad is sufficiently fast to move around the screen comfortably, it magnifies the usb mouse movement drastically, requiring careful cramped movement of the usb mouse to navigate because it's using the same movement speed and acceleration settings as the trackpad.

Greetings, I would like that more support to tuner cards of TV was included, example the card TV BOX USB with chipset: Trident 5600, I believe that this more is oriented to kernel of linux, but hope that the people of ubuntu can help with this.

Saludos,

Me gustaría que se incluyera más soporte a tarjetas capturadoras de TV, ejemplo la tarjeta TV BOX USB con chipset: Trident 5600.
creo que esto es más orientado al kernel de linux, pero espero que la gente de ubuntu pueda ayudar con esto.

It would be nice if ubuntu can open a SSD hard drive formatted in exfat.
For it is the only one that is designed for SSD hard drives.

We should investigate ways to use LinuxBios/Openbios enabled hardware to provide a better user experience. Possibly even set up a team to meet with them and discuss.

Some ways it may help is:
- Shave time off bootup
- The ability to support ACPI maybe on hardware not supporting it correctly now
- Being able to support buggy hardware better
- New ways of booting the computer we never were able to do before (ie, boot straight into a media centre instantly)

If we push as ubuntu enabled computers, we could also try to get them to employ LinuxBios/Openbios so that more of the computer is open, and we can do a lot more with the hardware, instead of relying on firmware updates (that sometimes can only be applied in windows).

OpenBios also may benefit some motherboard manufacturers because they no longer need to pay money for the more commonly used bios.

We should try to 'become one with the hardware'. This lets us do this. And it doesn't hurt to take 2 or 3 hours out of some developers time to work on something that may make booting more configureless, the computer more stable, more features, and provide a means of booting quicker.

It would be great if when you select to install restricted nVidia drivers, it would install a menu option somewhere to access nvidia-settings. I didn't even know that nvidia-settings existed until months after installing Gutsy on my desktop. This is especially important because the default "Screen and Graphics" menu does not correctly interact with the restricted drivers. Either replacing this menu item with one to open nVidia settings (preferred) or at least adding an nVidia settings menu item when you install the restricted driver would be very helpful. Another (maybe better) option would be to make "Screen and Graphics" play nice with the nvidia drivers so nvidia-settings wouldn't be necessary, but I don't know how feasible that is.

A related problem is that "Screen and Graphics" and nvidia-settings battle over who should be writing to my xorg.conf file, and changing one can screw up the other.
