i'm not the maintainer of gdm but did write:

  http://sourceforge.net/projects/xdm-options/

FILE PERMISSION: i'd start by removing and re-installing gdm.  or 
even using a pre-packaged gdm.  pay particularly close attention to 
file permissions: if that is wrong you'll likely get strange behavior

COMPILING: are you sure you had all gnome libs to get full features 
when you compiled it?  or maybe a config file is missing that is not 
installed after compilign (that your supposed to make).  try getting 
debian's and use dpkg_mini(1) (needs ar(1)) to look at their file 
layout.

"using up VT".  have no idea what you mean.  first time i've heard 
that.  far as i know gdm uses the same VT every time unless your a 
wiz and ran it on more than one term (which might take some doing) 
using multiple heads.


 -nolisten tcp


i keep telling people: read the X manpages !  -nolisten tcp only 
blocks tcp from your localhost to your desktop (forcing socket use - 
if you care).  IT DOES NOT STOP REMOTE ACCESS BY TCP.  so your 
blocking yourself locally and allow internet users access that way ! 
(they'd still need a password unless gdm sudo is insecure somehow). 
 try it from any host but local you will see.  (ie, if you want to 
block all tcp use maybe a firewall, -nolisten tcp does NOT do it)

also.  X, xdm are like telnet (well better).  they are not fully 
secure you have to protect them as if you were protecting telnet(1) 
+ telnetd(1).  passwords will be clear text or weakly protected over 
internet unless you use a "private lan that is secured", or secure 
sockets or, something
