The chooser doesn't really show up when gdm runs the X server.  What you can
do is this:

In gdm.conf, in the [xdmcp] section, do these modifications:

Enable=true
HonorIndirect=true

in the [chooser] section, do this modification (assuming the server is called
'biglinuxmachine'):

Hosts=localhost,biglinuxmachine
Broadcast=false

You can then comment out any servers in the [servers] section.

Now you have to start X for an indirect connection.  You could add this
to your startup scripts (assuming I wrote this correctly):

( while :; do 
  /usr/bin/X11/X -indirect localhost
  sleep 10
  done ) &

Or something similar.  The line that really does all the work is the

/usr/bin/X11/X -indirect localhost

one.   That starts an X server and queries the local host.

I plan to implement this last step inside of gdm, but for now this isn't done
yet, so you have to use the above kluge.
