Public bug reported:
When I use the hotkey to increase the brightness it works for a very short time
(maybe 100ms), but then falls back immediately to the old brightness.
Decreasing the brightness works, but not all brightness states are possible. It
seems that only every second brightness state is used.
Interesting is, that the brightness applet of the gnome-power-manager package
is able to set the brightness. However, after setting the brightness with the
applet, the icon is changes to the sun with the red circle on it (I think it
wants to say: not working).
But it still works with the applet.
