Make sure your kernel has this patch: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=227ae10f17a5f2fd1307b7e582b603ef7bbb7e97 You can also try disabling tiling in your xorg config: Section "Device" Identifier "Radeon" Driver "radeon" Option "ColorTiling" "true" Option "ColorTiling2D" "true" EndSection
Hello, The kernel I was using was Linux ubuntu 3.13.0-8-generic #27-Ubuntu That patch you mention made it to #28, I have since tested with the updated kernel and the xorg.conf options you mention, neither have resulted in a fix. Regards

Sorry, logic inversion. try this: Section "Device" Identifier "Radeon" Driver "radeon" Option "ColorTiling" "false" Option "ColorTiling2D" "false" EndSection

Do you have access to a similar card? I can send you mine if you like, as I have a spare HD5450 I can use in the interim. Regards
