My brightness is set to 2.0, but everytime, in several minutes time, it resets back, so everything gets dark, and I have to use the Video menu to get it back up.

It's really annoying. Can someone please help? Binding didn't help either (bind x "seta r_gamma 2.000000"). Doesn't do a thing.
I have an Ati Radeon 9600 XT, if it helps for someone. Thanks in advance, guys!
