Interesting. Could you report another bug about that crash in xserver- xorg? That's probably the place where the bug occurs. See https://wiki.ubuntu.com/X/Troubleshooting/Freeze.
This report can be kept to determine why crashing while a guest session is open will leave those files. That's a real issue on the long term - even if the system should not crash... ** Summary changed: - usermod fails: "cannot lock /etc/passwd" + System crash in guest session locks /etc/passwd forever -- System crash in guest session locks /etc/passwd forever https://bugs.launchpad.net/bugs/432964 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
