I believe this is just a side-effect of the nvidia driver not installing properly with the 4.2, 4.3, or 4.4 series kernels. I found this in JournalErrors:
Jan 29 07:26:56 username-AMD-desktop kernel: nvidia: module license 'NVIDIA' taints kernel. Jan 29 07:26:56 username-AMD-desktop kernel: Disabling lock debugging due to kernel taint Jan 29 07:26:56 username-AMD-desktop kernel: nvidia: Unknown symbol mtrr_del (err 0) Jan 29 07:26:56 username-AMD-desktop kernel: nvidia: Unknown symbol mtrr_add (err 0) So currently it affects Wily, Xenial, and the Trusty dailies w/Wily kernel. I'm not tech savvy enough to know which bug(s) may be the actual culprit, but I think either bug 1477593 or 1498146. I realize those are for different nvidia driver versions but there are duplicates that point to nvidia-304. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1539597 Title: unity-control-center crashed with SIGSEGV in _cogl_renderer_handle_native_event() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-control-center/+bug/1539597/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
