If the mouse cursor still moves then that means Xorg is still running and it was gnome-shell frozen. But we need to find out if it was just frozen or the result of a crash. Please use this command:
pidof gnome-shell to check the process ID before and after the freeze and tell us if it changes. Also immediately after the next freeze please run: journalctl -b0 > post-freeze.txt and attach the resulting text file here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1885330 Title: System unresponsive to keyboard and mouse clicks when changing screen background To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1885330/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
