Comment # 13 on bug 1028575 from Mircea Kitsune

I'm happy to announce that since xorg-x11-server 1.19.3 and / or xf86-video-ati
7.9.0 the issue appears to have been remedied. I now have over 5 days of
uptime, with not a single GPU freeze caused by the desktop. If by chance the
problem returns, I'll definitely post an update and let everyone know. It would
be very appreciated if in the future, the openSUSE team and driver developers
could please consider more in-depth testing for GPU lockups, to prevent this
sort of thing from repeating.

I imagine this issue can be marked as resolved. I will reopen it if I see the
problem happening again. Feel free to otherwise reopen it if anyone believes
there's still something to investigate.
