The most common issue we're seeing in this area right now is that gnome- shell crashes on lock, and so locking fails. That's bug 1877774 with a fix coming soon. Please also check /var/crash in case there is any evidence there (it might be a different crash).
Secondly, we find extensions cause a lot of bugs in gnome-shell. So please try without these: 'system-moni...@paradoxxx.zero.gmail.com', 'topic...@phocean.net', 'pixel-sa...@deadalnix.me' ** Changed in: gnome-shell (Ubuntu) Status: New => 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/1882462 Title: Displays wake up pre-maturely (likely driven by notification) Status in gnome-shell package in Ubuntu: Incomplete Bug description: After a period of time, my displays go to sleep as they should. However, I often come back to find that the displays are awake, the mouse pointer is on a screen, but the screens are otherwise black. They're in this weird "awake but not fully on" mode. At that point, they will not go back to sleep as they should unless I fully awake them and let them go back to sleep. I don't know exactly what triggers the "half awake" but I suspect it's a notification. The displays shouldn't turn on without a user action. It wastes power and is clearly broken. I've attached a photo for an example.
