Public bug reported: 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 AGPMode needed: 4 Model: Abit AV8 Host Bridge: VIA Technologies, Inc.
