Found the issue when looking at `/var/log/apport.log`. This may be useful for other people to whom you ask to do that workaround:
RROR: apport (pid 2496) Tue Mar 6 21:33:37 2018: apport: report /var/crash/_usr_bin_gnome-shell.1000.crash already exists and unseen, doing nothing to avoid disk usage DoS So I removed the crashes I already had in /var/crash. Will reproduce the crash now and report back in a moment. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1753658 Title: Xorg crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1753658/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
