Version: (using KDE 4.2.90) OS: Linux Installed from: Ubuntu Packages When I move the brightness slider in the Power Management applet, the screen brightness doesn't actually change. Most likely, I don't have the right drivers: "lshal" doesn't mention brightness, and /sys/class/backlight/ is empty. If that's the case, the applet shouldn't show the brightness widget.
Just wanted to confirm: I was missing the drivers, and it works correctly after I installed them. Still, I think it's a bug that the slider is there when the drivers are missing.
What do you mean by "drivers" ? Which ones? some kernel modules related to power ? Thanks
Yes, I was missing the "nvidia_bl" kernel module.
I've this implemented locally for KDE 4.4.4. Just have to checkout trunk and port my patch.
Rafał: awesome :) can you post the resulting patch to reviewboard.kde.org when you do so? (or you could just post the patch as-is to plasma-devel if you aren't going to get to the porting-to-trunk anytime soon)

SVN commit 1158799 by sebas: Revert r1157716: control amount of brightness sliders This patch produces 4 sliders on my machine (thinkpad T60). As 4 sliders on OK machines are worse than 1 slider We have to revert it for now until we find a proper solution for it. I don't see anything I'd happily commit to the stable branch, so I'll backport this one and we'll let the bug in until we have something that works *and* doesn't break machines that are otherwise OK.
