Auto brightness is not working on MacBook Pro OS X Lion

I recently upgraded to OS X Lion and I noticed that Auto brightness isn't working anymore on my Pro. I'm really not sure how to go about fixing this, if there is a way to fix this. Any and all suggestions are appreciated, though.

MacBook Pro, Mac OS X (10.7)
