[Bug 591963] Re: [Needs AGPMode quirk] X freeze + font corruption on Radeon 9600

[Jere Kupari]

** Description changed:

  Since gutsy I've had 
     Option "BusType" "PCI"
  in my xorg.conf, because my X would otherwise freeze in minutes.
  
  Now, after updating to lucid, the freeze was fixed, but fonts would
  corrupt. Sometimes a glyph would turn into something resembling a pause-
  symbol (play/pause double bar). Sometimes the glyph would just disappear
  and turn to white space. And some colours changed, e.g. everything
  written in black could turn bright green. OpenGL was also affected,
  Emilia Pinball would be dark and garbled.
  
  Then I found https://wiki.ubuntu.com/X/KernelModeSetting  After disabling KMS with 
     options radeon modeset=0
  in /etc/modprobe.d/radeon-kms.conf I had the freeze issue again, and some (but not all) corruption problems got fixed. 
  
  It seems that wrong AGPmode was the reason for all these problems, here
  is the information asked in https://wiki.ubuntu.com/X/Quirks
