For xdm, add -listen tcp to your Xserver specification, i.e., in 	
/usr/local/etc/X11/xdm/Xservers,

:0 local /usr/local/bin/X -terminate -listen tcp :0

CDE's dtlogin's Xservers file serves the same purpose

The moral of the story is, whatever your desired method of starting your 
Xserver, check the man page. Most display managers will have a 
configuration file to specify how to invoke the Xserver. I don't know about 
gdm, kdm or sddm.

Normally one doesn't need to fiddle around with this as ssh tunnels X. 
However, in my experience tunneling through an ssh session is slow. If 
you're on a private network, like I am (I'm the only one using my network) 
opening an unencrypted X TCP socket is fine. But if you're sharing that 
network with other, i.e. work, school, etc., tunnel through ssh. The rule 
of thumb is, tunnel through ssh.
