gdm gets stuck if not moving mouse
I was sent here by https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1778566.
When Wayland is activated in GDM, nothing happens when selecting an account with the keyboard or typing in the password. I have to type, then wait, then move the mouse around for the characters to appears.
Because I wouldn't believe this report if I received it, I made a video of the problem: https://peertube.mastodon.host/videos/watch/a4d02b33-d71e-4b0e-82cf-f2a74f952ca5. Note how no keyboard input is registered until the mouse cursor is moved sufficiently long.
Moving from Wayland to X makes the issue disappear.
There are a bunch of logfiles linked in the launchpad report, but I still have access to the system, I can always provide more information.
