Public bug reported:
I have my laptop connected to a projector through HDMI. When I have
"Join Displays" active, and then use Super Key + P to switch to external
only, the OS crashes to the login screen. It also happens if I have
External Only already on and close the laptop lid. It doesn't happen
every single time.
