[gdm-list] Remote (XDMCP) only gdm config - Fedora 18

[G Crowe <gcgdmlist crowie net>]

I have a server (a virtual machine, to be precise) that I need to connect to via 
XDMCP. I don't want to have it start a local session on the console (I don't 
believe that the console would even support it).

I have copied a following config file (see below) from a CentOS 5.2 box which 
works as expected.

It appears to still be trying to start local X-Servers and failing, and I get 
errors in the logs when trying to connect via XDMCP (and no successful connection).

Can someone please assist with my config file, or a pointer to some relevant 
(and recent) documentation.


Thank you

G Crowe
