Display :0 won't work for me as :0 in my multiseat the underlying x
session, the one that spans all monitors.  Each monitor then has Xephyr
running on it which use gdm to log in....  The display numbers start with
:1.

I know this has come up before; is there some architectural reason why gdm
won't support autologin on an arbitrary display?  Or would it just require
gobs of coding or something?  I say this never having looked at gdm code
at all, so I know not whereof I speak.
