Bug Description
Binary package hint: xserver-
The LCD brightness stopped to work correctly since I've upgraded to 9.04 Jaunty. It works fine in MacOSX 10.4.
My model is Macbook1,1 and brightness worked perfectly in 8.10 Intrepid.
At 100% the display brightness goes 100%:
decreasing the brightness level by 1, the display goes 0% (no light)
decreasing the brightness level by 1, nothing changes
decreasing the brightness level by 1, nothing changes
decreasing the brightness level by 1, nothing changes
decreasing the brightness level by 1, nothing changes
decreasing the brightness level by 1, the display goes around 50-80% (not sure) ...
decreasing the brightness level by 1, the display goes around 20-30% (not sure) ...
decreasing the brightness level by 1, the display goes around 30-40% (not sure) ...
the display brightness is completely different if I increase the brightness.
So the behaviour is kind of erratic and useless... I've tried both gnome-brightnes
Please tell me if you need more info.
