Public bug reported: About a month ago, GDM ceased to work. I opened another issue here https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1908717 but due to me using oibaf's ppa it was considered prudent to discard that issue and re-open after I removed the ppa and restored Ubuntu's dist packages.
Upon boot, gdm goes to a black screen with a cursor. This screen flickers to show the underlying tty and on each flicker the cursor position resets to the bottom right. It will do this a number of times until GDM dies and I'm left on a tty. I can start my window manager (sway) without issue from the console still and everything functions normally.
