Comment 0 for bug 925690

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.
