xorg log

Hello,

I have a radeon HD 4850 using X.Org X Server 1.9.4 and radeon 6.14.0. Whenever i start a X app such as xterm the screen gets swizzled. Taking a screenshot the image looks unaffected though it is impossible to see what is on the screen. Taking a pic of it, here is the situation before launching xterm http://medericboquien.eu/IMG_9892.JPG and here is the situation after http://medericboquien.eu/IMG_9893.JPG

(it looks like for some reason it filed the bug prematurely as i attached the xorg log file)

I have a 2 screen setup with xinerama. The xorg.conf file is the following.

I am using the standard Arch linux packages.

After testing i get a similar bug both under KDE 4.6.1 and under a TWM session in which just displaying the menu is enough to trigger the bug. Neither Qt, GTK nor Java apps seem to trigger the bug.

Thank you very much!

Following Fredrik Höglund's suggestion in IRC to turn colortiling to off in xorg.conf, it solves the problem. I hope it helps narrowing down the bug.

Thanks!
