It turns out, strange as it seems, that in order for the:
$DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN to "yes"
change to work, a reboot was actually necessary.
Restarting the X server (done via kdm at the login window) was not enough (I
read somewhere on the web that all you have to do is restart the X server).
I did try a reboot before, but apparently something else was different
too...
Just FYI.
Thanks,
~ Jeremy
