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

Title:
Desktop does not load after login - purple screen with mouse
Status in mutter package in Ubuntu:
Incomplete
Status in xorg-server package in Ubuntu:
Incomplete
Bug description:
When logging in, the screen goes purple and blank, but I can still
move the mouse. Keyboard shortcuts such as Alt+F2 or Ctrl+Alt+T have
no effect. I can use Ctrl+Alt+F[1345...] to switch to a shell or go
back to the login screen, but Ctrl+Alt+F2 puts me back in the blank
state. When turning off the computer from the login screen, I get a
warning that my user is logged in.
The most similar previous bug report I've been able to find is
https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1766137. However,
my problem occurs regardless of whether I fail the first login attempt
or not, or whether I enter my password or scan my fingerprint.
I have replicated the problem booting with two kernel versions: Linux
5.8.0-44 and Linux 5.8.0-43
I have been using the computer since November 2020, and this problem
occurred for the first time when I rebooted it this weekend (Sat
2021-03-13). I have previously had trouble getting getting external
monitors to work, but even that has worked fine for the past few
months.
