The first error message appears 50 seconds after graphical login. Then, error messages appear every few minutes.
The problem occurs only when logged as a main user (user which is able to make sudo and gain admin/root privileges). The problem does _not_ occur when logging in as a normal user (user that cannot sudo) or as guest. The problem was covered also by Bugs # 983640, 975624 and 1160926 but no solution is found. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1162366 Title: Repeated GPU lockup error messages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1162366/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
