airlied: oh I need to test fast-user-switch some more... airlied: yes starting the second X server might cause problems airlied: switching back to the first server is possibly broken. airlied: yup.. so I guess I'll play with switching once I get the current bits done. airlied: pretty much from what I can see. airlied: I'll play around today/tomorrow and see what I can fix.
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Is this still happening with -61 and -137 kernel?
ATI & KMS has improved a lot, thanks! But because of bug 466598 I can't use KMS on a daily basis and thus can't give it heavy testing right now. But I will leave it assigned and come back to it soon.
Some testing shows that it seems to work OK. But I couldn't reproduce it on demand before, so my testing doesn't prove much. If you think it is solved then please close it - I will reopen if I see it again. BUT then I switched to a user who had compiz. At first it worked fine, but when I switched back to non-compiz I got horrible corruption. Big tiles had been moved around. I don't know if this is related ...
That is long time ago, things have changed, and this report no longer has any value. Closing.
