it gets worse after some time
graphics corruption get worse after some time.
Hmmm, now I get graphics corruption on the second display as well. So it does not seem to be limited to the first display Its difficult to say, when this last did not happen. It certainly didn't happen without before I enabled Radeon KMS on kernel 2.6.33. But I think I didn't see this in 2.6.33 either. Then bug #28402 let me skip some kernel versions. I am not sure about 2.6.35 with patch for bug #28402 tough. Even more difficult to say for userspace versions. Ok, these corruption does not seem to appear when I disabled compositing by pressing Alt-Shift-F12 on display :0 and shortly after I start the second KDE session on display :1 as well. So this seems to be related to having to instances of Radeon KMS X.org displays running at the same time. Since I already tried with :1 without compositing, it might be sufficient, when :0 runs without compositing. I try with :0 without and :1 with compositing after I am confident that both without compositing run stable. Bug 23622 - probably radeon kms / memory shortage related scheduling while atomic https://bugzilla.kernel.org/show_bug.cgi?id=23622 might be related to this one. I will also compile a 2.6.37-rc3 and test it as well. Currently testing with 2.6.37-rc3. Running two sessions for about an hour and no graphics corruption yet. So there is hope that this issue has been fixed in the meanwhile. Thanks. Two quick. Graphics corruption still happened, it took a bit longer but then some small corruptions appeared and it got worse again. Thus disabling compositing on both desktops for now. That appears to work. Hmmm, it seems to me, that graphics corruptions occur after the first TTM memory allocation failure messages which I reported to Bug 23622 - probably radeon kms / memory shortage related scheduling while atomic https://bugzilla.kernel.org/show_bug.cgi?id=23622 Mass closure: This bug has been untouched for more than six years, and is not obviously still valid. Please reopen this bug or file a new report if you continue to experience issues with current releases. |
