Version: (using KDE 4.2.0) OS: Linux Installed from: Fedora RPMs I can't control the brightness of my notebook. When I move the slider in the plasma applet nothing works (the brightness remains the same), when I try to do it through the shell I don't see any changes: ### [cimi@gemini ~]$ solid-powermanagement brightness set 100 Setting brightness to 100% [cimi@gemini ~]$ solid-powermanagement brightness get Brightness is 0% ### and this is the output of lshal | grep -i bright: ### [cimi@gemini ~]$ lshal | grep -i bright input.keymap.data = {'e002:displaytoggle', 'e003:battery', 'e004:prog1', 'e006:wlan', 'e008:brightnessup', 'e009:brightnessdown', 'e031:prog2', 'e033:prog3', 'e034:wlan', '0074:prog1', '0075:www', 'e077:f22', '0078:mail', 'e079:f22'} (string list) ### Samsung NC10
I forgot to say that with xbacklight everything seems to work fine, gnome-power-manager can handle it too.
Is your user in the "power" group? I'm moving this to solid since the issue seems lying there.

We're talking about this in #solid now. (oh, btw, sorry if I haven't answered to your PM, I'm under heavy exams and I'm taking a small break today only :) )
in kubuntu 9.04 alpha brightness control work using plasma applet but not using fn-keys :(
Same problem here: Hardware: Samsung NC10 anyNet 270BH Distribution: Gentoo Kernel: 2.6.29 (Vanilla) KDE: 4.2.1 (Vanilla)
It works here now using the brightness slider of powerdevil: - set the backlight control in the BIOS to manual - upgraded to kernel 2.6.29 - upgraded to KDE 4.2.2
Any updates for you other affected people? It works here since quite some time.
Hi guys, I'm on kuubuntu karmic fully updated. No Fn keys and the slider in powerdevil does not work. :-(
(In reply to comment #9) > Hi guys, > I'm on kuubuntu karmic fully updated. No Fn keys and the slider in powerdevil > does not work. :-( Have you set the brightness control in the BIOS to "manual"? There's also a FDO-Bug about the video driver: http://bugs.freedesktop.org/show_bug.cgi?id=20963
Hey, this issue isn't just for KDE I found out, as a user who was experiencing it on KDE tried out the Ubuntu Netbook Remix and is faced with the same exact problem using Karmic right now. https://bugs.edge.launchpad.net/ubuntu/+source/kdebase-workspace/+bug/417651
https://bugs.launchpad.net/bugs/438763 - shows it needs a special kernel module, which seems to have been flakely as of late in Ubuntu Karmic.
Given the last comments I'm marking the bug as upstream
Upgrading BIOS to 011CA fix backlight control for me. kernel 2.6.33.4 kde 4.4.3
