I tried the wikipedia example and got my old friend again:
--------------------------------------------------
[root@iam log]# Xvfb :1 &
[1] 6791
[root@iam log]# xv -display :1 &
[2] 6793
[root@iam log]# AUDIT: Mon Aug 11 23:26:37 2008: 6791 Xvfb: client 1
rejected from local host (uid 0)
Xlib: connection to ":1.0" refused by server
Xlib: No protocol specified

xv: Can't open display
---------------------------------------------------

THAT kinda error is typical of that which busts my jewels.
Does anyone suppose that it's related to gdm?? Should I use xdm?? Is
there some securetty config file to edit or something of that nature??
Xvfb seems to want to work, but somehow gets rejected. REFUSED! This
stick has beaten me for several months or more. I could use some
relief! :) Ric

Ric,

read this:

Your error is there. I used to use something like this for connecting
my TV to :1. I call the script "display.auth"  :

#!/bin/sh
# Allows the use of :1 for X.
# By default the file /tmp/.gdmxxxxxx is used.
# At each new session this script should be run.
#
xauth add "$(/bin/hostname)/unix:1" MIT-MAGIC-COOKIE-1 \
$( xauth list | egrep "$(/bin/hostname)/unix:0" | awk '{print $3}' )
