Public bug reported:
When gnome-power-manager is running I attempt to change the screen
brightness. The indicator shows that it changes over 3 different steps.
The result is that the brightness does not change at all.
It would be just super awesome to see the brightness change - and have it
change over a much wider range of values. 10 or 15 steps would be better.
Especially if the brightness actually changes too. :P
