I can't even get into the login screen when the DisplayPort device is attached. But I disconnected that, got to gdm login via the VGA device, then switched to Ubuntu on Wayland. Ubuntu on Wayland works fine for me generally, but I get the same behavior when connecting the DisplayPort device after logging in. I've included a video of the behavior here: https://photos.app.goo.gl/aJSx5stMMg7QZULH6
