[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.
