FWIW, from either the logged in session or it's lock screen (if the user
has locked it) just select the "Switch User" function (either in the
user menu in the top right if logged in, or the big button from the lock
screen). This will tell GDM to spawn a new login manager for you.

I asked a log time ago if we could have some kind of autospawning of a
gdm screen on tty2 as soon as you switch to it (much like getty will
autospawn). I don't think it would be too hard to glue that together
these days, but not sure anyone has done that.
