For me, this bug is easily reproducible (happens within 1 min. of user session start) on xserver-xorg-video-nouveau 1.0.2
My user X session is compiz + classic + upstream gnome-panel + Radiance theme on NV84. The stack trace is nearly identical to the original reporter's (I do get 'Failed to idle' or 'Unexpected page flip' at other times but those seem unrelated to this bug). This bug has been low-priority for me because it doesn't seem to affect stability. This bug is _not_ reproducible with ppa:mlankhorst/ppa xserver-xorg- video-nouveau 1.0.6+spam~quantal2. Let me know if bisect is required. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1033533 Title: Xorg crashed with SIGABRT: exaMemcpyBox with src=0x0 on nouveau with SW rendering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1033533/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
