Actually I finally got off my lazy ass and looked at the gdm.conf file and
towards the end of it there's a commented out entry for an additional
server.  Turns out if you uncomment that entry and add a few more just like
it (incrementing the server number), then gdm will start multiple X servers,
each on its own virtual console.  You can then log in via gdm on all of the
X servers as different users simultaneously (although it's gonna be tough to
get keyboard time). :-)

So I guess the answer is that you just decide how many simultaneous X
sessions you want to allow on the local physical console, then define that
many X servers in gdm.conf, then kill -USR1 the parent gdm (the one started
by init), then log out.  When you log out, gdm will restart the X server
(unless you told it not to do that by changing another option in gdm.conf),
and when it comes back up gdm will also have started additional X servers on
other virtual consoles.

I wish it didn't need to keep the unused X servers running on the other
consoles all the time though...

-t.

not sure either but one thought is the gdmXnestchooser program, fires up
Xnest(a sort of virtual X server, runs on top of X), and a gdm chooser
(provided your running gdm on localhost with XDCMP(?) enabled). Then
you can connect to the localhost(or another host which has GDM), and
login. quite cool. redhat 7.3 as far as I know doesn't have this feature,
but newer versions probably do(haven't tried 8 or 9 myself).
