[Bug 548709] Re: Radeon gamma bug, display too bright when using VGA
** Description changed:
Binary package hint: xserver-xorg-video-ati
Ubuntu Lucid Lynx radeon driver has a bug, which causes
gamma/contrast/brightness settings to be messed up.
http://ubuntuforums.org/showthread.php?t=1438810
Display is okay with Karmic Koala kernel 2.6.31-20.
Using xgamma, to lower gamma makes it worse.
