Thanks. Yes the messages about "Memory pressure relief" sound unusual. I've never seen that before.
Don't worry about the inability to switch VTs. That's not part of the bug, that's just because switching VTs is the responsibility of the currently active display server. If Xorg has frozen then you also won't be able to switch VTs. Next, please monitor the memory usage of your processes before the next freeze happens, with something like: ps auxw --sort -rss | head so we can identify if and what is using too much memory. In case the issue is gnome-shell like it sounds, please also ensure you have uninstalled all third-party gnome-shell extensions except for the standard Ubuntu ones. ** Tags added: nvidia ** Summary changed: - Xorg freeze + [nvidia] System freeze ** Package changed: xorg-server (Ubuntu) => ubuntu -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1861043 Title: [nvidia] System freeze Status in Ubuntu: Incomplete Bug description: So under high load I can generally cause a freeze in Gnome/Ubuntu. This is somewhat expected and likely should be fixed by some sort of OOM killer. However that's only part of the problem. Virtual Consoles are disabled (`/etc/systemd/logind.conf` `NAutoVTs` by default) and I believe that too to be a bug. In the past I could have Switched VT's logged in and killed of a high memory/cpu process or two. Now I have to hard kill the box and risk loosing in progress work which is ungainly. If there's a worry about "what will new users do if they accidentally hit CTRL+ALT+F\d" maybe instead of disabling it we could change the default login message to have a "Don't know how you got here? Hit CTLR+ALT+F1 to go back." Also because I have to hard restart apport never get's called to show exactly why the system is hanging.
