[Bug 636053] [NEW] Screen brightness won't change on Acer Asipre 5741

Sat Sep 11 22:23:38 UTC 2010

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
