Next time the problem happens, log into a tty and find the PID of the frozen gnome-shell process. Then run:
apport-cli --hanging -P PID where PID is the process ID of the frozen gnome-shell process (which is the one running as your own user ID, not gdm). That should create a new bug/crash report. Please send us a link to that. ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1836881 Title: gnome-shell freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1836881/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
