No gamma adjustment in opengl, no gamma adjustment anywhere. I already posted this issue earlier in some other thread, but let's repeat it here: when screensaver activates, screen doesn't dim first (as it should do). And there's no gamma adjustment anywhere, except in the "catalyst control center".
Also OpenGL games are very slow if aiglx is enabled in the xorg.conf and compiz is not running. If I re-enable compiz, then everything flickers awfully in all opengl apps.
I'm running Ubuntu Gutsy on Lenovo T60 w Mobility Radeon X1400.
