With stock kernel I can reproduce my issue less then in a hour. And this is ubuntu's mainline repo.
Seems I have a bit different error with same result, but you may try. You can always boot to stock kernel. I hope this testing result will point ubuntu kernel team to backport driver changes. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/775060 Title: Random GUI "freezes" in Natty (can only move the cursor) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/775060/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
