Public bug reported:
I'm using Oneiric x64. When I press fn+left/right arrow keys the
brightness of the screen doesn't change even thou the bar appears on the
top right corner correctly. This laptop has two video cards: nVidia 540M
and an integrated Intel HD Graphics 3000. Normally the nVidia card is
switched off by Bumblebee so only the Intel one is running.
