Description of problem: When I start Fedora 14 on my Macbook Pro the brightness of the display will be reduced during the startup phase of KDE-4.5.2 and I cant increase or decrease the brightness with the softkeys on the keyboard. This issue doesn't occurs on GNOME !!! Version-Release number of selected component (if applicable): KDE-4.5.2 How reproducible: Start KDE-4.5.2 on Fedora 13 or Fedora 14 Actual results: Brightness will be reduced can can not been modified Expected results: Brightness should not been reduced. Brightness should be modified by using the softkeys on the keyboard. Additional info: This happens on the late 2009 15.4" Apple MacBook Pro. The issue doesn't occurs on KDE releases previous as 4.5 and on GNOME
> The issue doesn't occurs on KDE releases previous as 4.5 => adding to the 4.5 tracker
dupe of #539961 ?
heh, almost certainly (kde uses hal to do the heavy lifting). Not sure if we should depend on it, or dup it... (let's just mark the dep for now).
Same problem on alu iMac 20'' but with a difference: it doesn't work in Gnome either!
I think the issue is that the kind of how the backlight brighness is controlled on a Mac is depends on the modell you have. Differnent modells of the Macaintosh has different controller and so different ways how to control the backlight brightness on it. So I will suggest the usage of the sysfs interface to controll of the brighness oI f the backlight. After you have determinate the right path the kind of control should be simular on all Macaintosh modells. For more details I want to reference to the sysfs_backlight.c file from the pommed project.
Is this related to http://bugs.kde.org/show_bug.cgi?id=246521 ? You can check that by trying to change brightness with commands: solid-powermanagement brightness set [value] If the command works, it's probably the same bug.
The command at comment #6 works fine for me and the but is not fixed on KDE 4.5.5.
I could perhaps whip up a quick-n-dirty scratch build including the upstream patch, http://websvn.kde.org/?revision=1214119&view=revision
Created attachment 474131 [details] Backport of upstream patch to solve brightness issue in KDE 4.5.5 this patch should fix the brightness issue in kDE 4.5.5. On my system (MacBook Pro late 2009) it's works fine.

How about Gnome? Brightness keys display the brightness value going up/down, but there is no actual change in screen brightness. (MBP 6.2)
If GNOME is broken the same way, please file a different bug against GNOME, it's apparently not the same code which is faulty.

Yes, the problem is still there. I updated to kde-workspace 4.5.5-2 but still nothing happens when brightness buttons are hit on the keybord.
