Thanks for the bug report. It appears the computer is in recovery/low graphics mode according to these kernel parameters "recovery nomodeset" and the Xorg log concurs in using "FBDEV". If you did that just to report this bug then that's OK, please just run this command to collect some logs of when the bug was occurring:
journalctl -b-1 > journal1.txt journalctl -b-2 > journal2.txt journalctl -b-3 > journal3.txt and attach the resulting text files here. If you are not in recovery mode intentionally then please reboot, tap Esc before Ubuntu starts, and be sure to select the regular non-recovery kernel. Separately, please install the Nvidia driver, either by the 'Additional Drivers' app or by running: sudo apt install nvidia-driver-460 ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) ** Also affects: mutter (Ubuntu) Importance: Undecided Status: New ** Changed in: mutter (Ubuntu) Status: New => Incomplete ** Changed in: xorg-server (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1919093 Title: Desktop does not load after login - purple screen with mouse To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1919093/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
