Please describe the problem:
A fundamental feature of X windows is that it is a networked window system that allows the display of remote windows.

In previous versions of GDM it has always been possible to enable this feature using gdmsetup or by editing the GDM configuration file. In 2.22 this feature has apparently been removed so that GDM now always starts X with the "-nolisten tcp" switch to stop it accepting network connections.

This is a major regression that seriously impacts the functionality of any X server started by GDM.

Steps to reproduce:
1. Login via GDM
2. Note that remote windows cannot be displayed
3. Try and run gdmsetup, find it's not there anymore
4. Google high and low to find out how to enable TCP in GDM 2.22
5. Eventually find http://mail.gnome.org/archives/gdm-list/2008-April/msg00021.html


Actual results:
I get very annoyed

Expected results:
I would expect to find a way of allowing TCP connections to my X server

Does this happen every time?
Yes
