Comment 3 for bug 1809407

I did some random trial and error debugging.

There's always a login screen on console 1 and there's always a desktop GUI on console 2. It's sometimes waking from sleep into display 2 while still locked. There's a dock, a system menu, and random bitmap garbage. Hitting CTRL-ALT-F1 goes to the login screen. After logging in, it jumps to a normally working display 2.

Not sure if it's related: CTRL-ALT-fkey is sometimes generating app keyboard events rather than switching consoles.

Installing 18.04 completely corrupted my system and I had wipe the disk. This isn't an old crusty installation.
