Thanks for the bug report. First please check that you don't have any extensions aside from the three Ubuntu extensions installed. Look in the 'Extensions' app and also run:
cd ~/.local/share/gnome-shell rm -rf extensions then log in again. Second, you seem to be using a Xorg session(?) so we can identify which part of the system has crashed or frozen by whether the mouse pointer still moves. Does the mouse pointer still move? Finally, next time the bug happens, please: 1. Wait 10 seconds. 2. Reboot. 3. Run: journalctl -b-1 > prevboot.txt 4. Attach the resulting text file here. ** Package changed: gnome-session (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/1952976 Title: gnome fails to respond To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1952976/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
