Sadly, since this happens typically once every 1-3 days, and on a work machine, with 14.04 required, so I'm not really able to try out a fresh install. It might be worth my while trying out the LTS stack, to get a more recent kernel. Right now I'm having a problem installing the utopic LTS (https://wiki.ubuntu.com/Kernel/LTSEnablementStack), but if I can get past that I'll see if it improves things.
It did happen to me yesterday with no syslog message apart from "[drm] stuck on render ring". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1366876 Title: Xorg freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1366876/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
