Bug Description

on a netbook ASUs VX6
with 12.04 it worked well: Fn+F5 to make the screen less bright and Fn+F6 to make it brighter.
since upgraded on 14.04 the brightness seems to be locked.
the transparent scale on the top-right of the screen still goes on and the cursor also moves sideways but the brightness doesnt variate. only after a restart the change gets effective.
thank you for your help
