Public bug reported: 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.
