Public bug reported: Xorg crashes when I logout and login as a different user from KDM for the first time. I am returned to the login screen with compositing automatically disabled. The second and further logins work. I have to manually enable compositing by going into System Settings -> Desktop Effects.
This has started affecting me only since Oneiric. For each such crash, I see the following line in kern.log: [drm:i915_gem_do_execbuffer] *ERROR* Object ffff88022c927400 [handle 650, index 1] appears more than once in object list ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: xserver-xorg-core 2:1.10.4-1ubuntu4.2 ProcVersionSignature: Ubuntu 3.0.0-13.22-generic 3.0.6 Uname: Linux 3.0.0-13-generic x86_64 ApportVersion: 1.23-0ubuntu4 Architecture: amd64 Date: Sun Nov 27 13:58:45 2011 ExecutablePath: /usr/bin/Xorg InstallationMedia: Ubuntu 11.04 "Natty Narwhal" - Release amd64 (20110426) ProcEnviron: LANGUAGE=en_IN:en PATH=(custom, no user) LANG=en_IN SourcePackage: xorg-server UpgradeStatus: Upgraded to oneiric on 2011-10-15 (43 days ago) ** Affects: xorg-server (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug oneiric -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/896803 Title: xorg crashes on first login with compositing enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/896803/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
