Since removing - gnome-shell-extension-multi-monitors - gnome-shell-extension-system-monitor The issue is no more triggering.
Thanks as it resolved my issue. I'm not sure if we can do much more, lets keep it incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1813248 Title: Hang at screen unlock (gdm / 18.04) Status in gnome-shell package in Ubuntu: Incomplete Bug description: For two days in a row (one would have been a one-off WTF that I don't care to report) my system now hang after unlocking from the UI. I can't see any obvious hanging processes that would be the obvious reason. OVer day I have a few screen locks e.g. when going for lunch, but at least 2/2 times it only appeared when the lock was active over night. I'm not sure it if it the duration or that some job kicks in at night. I have used apport to collect the basics, and will add some more debug data. If you find a lead in there let me know, otherwise assuming I might face this every morning please let me know what to check next time it happens so that we can find the root cause. I found similar bug 1285258 - but other than there I can NOT hit cancel to get a second chance, nothing in the UI moves at all and all I can do is drop to a non UI console with CTRL+ALT+F3 and debug from there. I found that restarting gdm (systemctl restart gdm) gets me logged in, therefore I'll also attach a journal log so that you can look for issues in there.
