Bug Description
When changing the brightness on my Dell XPS 14" some incremental states of brightness are broken(leave the screen brightness completely off, and i cant see at all) on mine there are 16 states, the first 9 work then 10,11,12,13 are broken 14 works , and 15,16 are broken. (these numbers are going from max brightness going down so 1=max brightness)
This is extremely inconvenient for me, I cannot set the screen to dim in power savings because of this, and even worse in 11.10 because so far i don't see an option to turn that off at all in settings.
I am using the Nvidia binaries if that is important.
