Juan Pablo, thanks greatly for the gdb output, that actually helps a lot and gives me much more to go on. I have not found the source of the problem but this rules out several ideas, and gives us something we can finally take upstream.
I have gone through all the commentary on this bug, to compare everyone's chipsets: Juan Pablo: 945GM/GMS, 943/940GML Jose Bernardo: 945GM chipset michelem: Unreported unggnu: i915GM Sitsofe: 945GM/GMS/940GML bdmurray: 945GM/GMS, 943/940GML Tim Hull: Unreported chipset. "mac book" TBD: 945GM/GMS, 943/940GML Rengarajan: nvidia Quadro NVS 110M -> unrelated Jeff250: 915GM/GMS/910GML legolas558: Unreported chipset -> unrelated Gert Kulyk: 915GM Peter Weissg.: Unreported chipset Unfortunately, several people have failed to report their chipset, but if we disregard their reports, it's apparent that this is affecting just 945GM and 915GM. Also, some others who report "having this issue" turn up to have some completely unrelated issue that only appeared similar in symptoms to this one; we'll disregard these reports as well. It's clear that there are at least three different bugs that are presenting similar behavior: a) Juan Pablo's original issue, gray blocks on VT switch after disabling/enabling compiz b) 'XAA Evicting pixmaps': This went away after Tribe 4 c) ungnu's issue, bug 141063, which occurs only after playing videos via Xv. It's a little unclear sometimes when people report back "I'm having the same issue" after trying out various fixes, whether they are experiencing exactly Juan Pablo's issue, or ungnu's issue (or both, or neither). Possibly each of these bugs will be fixed by different things. -- laptop hangs when switching video mode https://bugs.launchpad.net/bugs/127101 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
