As another data point, I too am experiencing system freezes sporadically. Similar time spans to John. I find that switching to vc1 with Ctrl-Alt-F1, and then switching back to X thaws the freeze. When I switch back to X from vc1, the screen is black, but once I open the dash, parts of the screen are redrawn again and the computer becomes usuable.
This is a GTX 750 Ti. I am happy to provide any details. I'm not sure how to debug any further myself. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1288747 Title: [334] Parts of the UI randomly flicker when moving the mouse To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1288747/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
