It sounds like some part of the system has crashed. Please: 1. Apply the workaround from bug 994921.
2. Look in /var/crash for crash files and if found run: ubuntu-bug YOURFILE.crash and tell us the ID of the newly-created bug. 3. If step 2 failed then look at https://errors.ubuntu.com/user/ID where ID is the contents of the /var/lib/whoopsie/whoopsie-id file on the machine. Do you find any links to recent problems on the machine? If so then please send them to us. ** Changed in: xorg (Ubuntu) Status: New => Incomplete ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1779658 Title: Dropping to shell twice crashes system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1779658/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
