Oh, actually, I think I can see the problem in your logs. You have a proprietary Nvidia kernel driver installed but Xorg is using the (unstable) open source driver.
So the driver is not properly installed AND it seems to be the wrong version. Please install Nvidia driver version 440, which you should be able to do via the 'Additional Drivers' app. Then reboot. If the problem continues after that then please run: journalctl -b0 > journal.txt and attach the resulting text file here. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1890843 Title: Freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1890843/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
