After update to xf86-video-ati-6.14.0 and xorg-server-1.9.4-1, X will start and you will see the normal display manager. However on login, after you either close the first 'tips' window or open a menu, the display pixelates and wraps arround the display. Example:

I have experienced this exact same problem on Arch and opensuse. In Arch, downgrading to:


restores normal operation. I currently have my updates set to --ignore upgrade of these files to prevent breaking the display.

Since X and fluxbox or X and kde are running - there are no obvious errors in the Xorg.0.log file.

I have added the dmesg output to provide hardware information. What other information can I provide that would be helpful?

Steps to reproduce:
Update a box with Radeon X1250 card to xf86-video-ati-6.13.2-2 and xorg-server- Boot to display manager and log in. On first window open or close (sometimes in the greeter itself), the display pixelates and become unusable :(

Guys, this may be libgl in addition to an xorg problem. It has been confirmed on other distros as well. Basically EXA is broken for ATI and XAA works, but no 3D and the gpu performance is slow. Additional details can be found on the opensuse bugzilla:

As suggested in the above report, a workaround with XAA only is to modify the configuration in /etc/X11/xorg.conf.d/ and set:

Section "Module"
Disable "dri"
Disable "dri2"

Section "Device"
Identifier "Default Device"

Driver "radeonhd"
Option "AccelMethod" "xaa"

Is this still an issue with current versions of mesa, xf86-video-ati and xorg-server (preferably from testing)?
