Yes, the system is definitely unusable. The screen is black for about 30 seconds, and then the login screen appears.
Obviously, all running programs have been stopped, which means a potential data loss. Today it happened two times in a row, both times when Shift-clicking on the “Reply” button at an e-mail in Thunderbird. In the last three weeks while on Wily I've had this crash five or six times. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1503159 Title: Xorg crashed with SIGABRT To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1503159/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
