gdm enabling Xorg to listening on tcp

[Stephen Adler <adler stephenadler com>]

Guys,

You have a mechanism to turn off the use of the Xorg command line
option "-nolisten tcp" by setting "DisallowTCP=false" in the [security]
section of the <etc>/gdm/custom.conf file. The Xorg server now has "tcp
listening" turned off by default and if you wish to enable it, you need
to add the command line option "-listen tcp". How does one enable
listening on tcp withing the configuration framework of GDM? May I
suggest adding "AllowTCP=true" to the [security] section of the gdm
custom configuration file? Or is there another method of configuring
gdm so that when it starts the Xorg server it passed along "-listen
tcp" as one of the command line options?

Cheers. Steve.
