Thanks for the bug report. 1. Please check that you haven't enabled any additional GNOME extensions in the 'Extensions' app. There should only be the three built-in ones. If you have more than that then try uninstalling or disabling them.
2. Next time you have to "hard reboot", please then run this command in a Terminal window: journalctl -b-1 > prevboot.txt and attach the resulting text file here. 3. Please also check for any recent crashes using these instructions: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Incomplete ** Summary changed: - Xorg freeze + System freezes when in lockscreen ** Package changed: ubuntu => gnome-shell (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1913045 Title: System freezes when in lockscreen Status in gnome-shell package in Ubuntu: Incomplete Bug description: My system freezes when I'm in lockscreen. This happens every few ours after I leave the computer running some low to mediocre computation tasks, no memory problems. It does not happen when I run heavy tasks. I can only hard reboot, nothing else is working.
