Nish, To figure the problem out you will need to be logged in already while it's happening(!), so..
1. Log into a VT (Ctrl+Alt+F4) or install openssh-server and log in from a separate machine. 2. Run 'top' to find the ID of the spinning process. 3. Run: kill -ABRT <PID-of-spinning-process> 4. Wait a while for crash files to be written. 5. Look in /var/crash for crash files and run: ubuntu-bug /var/crash/YOURFILE.crash 6. Add a comment here telling us the ID of the new bug. ** Changed in: gdm3 (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1753576 Title: GDM freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1753576/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
