The FN-up/down hotkeys for increasing and decreasing brightness won't work in Gutsy Beta for me. I also had this bug in a development version of Feisty and then it could be fixed by adding "blacklist video" to /etc/modprobe.d/blacklist. When the final was out, I didn't need to blacklist the vid

[Bug 140782] Re: Inspiron 1420 LCD brightness keys broken

As stated in , you can control brightness using hotkeys by adding 'options video no_automatic_changes=0' to some file in /etc/modprobe.d/ and reloading the video module. I don't know why that change was made, b

I have a Dell XPS M1210. My LCD brightness can go down, but the keys can't bring it back up. If I start up the power management, I can use the slider to adjust the brightness. Here's the output of gnome-power-manager when trying to adjust the brightness. ** Attachment added: "gnome-power-manager

After booting in recovery mode, I can use hotkeys to change brightness. After doing "modprobe video", brightness hotkeys stop working. The only new module reported by lsmod is video. After doing "rmmod video", lsmod doesn't show the video module anymore, and modules shown are exactly the same as

[Bug 140782] Re: Inspiron 1420 LCD brightness keys broken

Agree with above. Before the update that broke my Fn brightness keys, software-driven brightness did work. kde-guidance-powermanager has a slider bar that controls brightness when connected to AC/battery, and those worked fine (and still do). I could also control brightness with the keyboard thoug

Re: [Bug 140782] Re: Inspiron 1420 LCD brightness keys broken

My thinking is that on these models we should just let the BIOS handle this, since it handles it very well, and doing it through userspace means: * We need to handle it in every environment - KDE, Gnome, pure console, X with no window manager, etc. * We need to make sure it's always responsive and

[Bug 140782] Re: Inspiron 1420 LCD brightness keys broken

I think that's correct for laptops with keys that only send a keypress event, but there're laptops who change brightness by hardware (probably by sending some signal to the BIOS). It's not desktop environment specific, since I can change brightness with hotkeys in grub menu, but not after the ac

[Bug 140782] Re: Inspiron 1420 LCD brightness keys broken

Backlight handling has to be handled by userspace. I'm punting this over to the general KDE task, because I'm honestly not sure which part of KDE should be taking responsibility for this. ** Changed in: kdebase (Ubuntu) Sourcepackagename: linux-source-2.6.22 => kdebase -- Inspiron 1420 LCD brigh

I don't think this is a bug in kpowersave, since I don't have it installed and never have. The closest thing I have to that is kde- guidance-powermanager (and I do have kubuntu-desktop and its dependencies installed). Has there been a recent change in the way these brightness keys are handled, so

@Matthew Garrett: The problem is that, when brightness max levels is more than 20, g-p-m use an increase/decrease step value of max_levels/20 (5%). So, in my case, acpi reports brigthness max levels=100, and possible brightness values are: 12 24 36 48 60 72 84 100. When I'm at 72, if I try to i

gnome-power-manager should be listening to keypresses and adjusting the brightness accordingly. Can you (from a shell) run killall gnome-power-manager gnome-power-manager --no-daemon --verbose 2>/tmp/output and then hit the brightness keys? Then ctrl+c it and attach /tmp/output and the output of
