Looks like your X server is getting started with a '-nolisten tcp'
argument.  Check the command line in gdm.conf.  Removing that argument
will allow the X server to listen for network connections such as those
coming to the 'localhost' address.

Depending on your environment you might want to configure a firewall to
protect your X server from netwrok connections from outside your machine.
