Running game in it's own Xserver

[KRavEN]

Anyone know how I can get this done under ubuntu? I've found a couple of scripts that will launch the game in it's own xserver instance when you fire it off but I'm having a permissions problem. I found the gentoo guide that talks about this and I set the permissions for display :1 using xauth but I still get the:

kraven@p4:~$ X :1
X: user not authorized to run the X server, aborting.

I can sudo start the :1, but if I launch the game on that server it immediatly crashes.

xauth looks like this:

kraven@p4:~$ xauth
Using authority file /home/kraven/.Xauthority
xauth> list
p4/unix:1 MIT-MAGIC-COOKIE-1 9737c9d384f66e732d90dd221c9bd81a
p4/unix:0 MIT-MAGIC-COOKIE-1 9737c9d384f66e732d90dd221c9bd81a
localhost.localdomain/unix:0 MIT-MAGIC-COOKIE-1 9737c9d384f66e732d90dd221c9bd81a
localhost.localdomain/unix:1 MIT-MAGIC-COOKIE-1 9737c9d384f66e732d90dd221c9bd81a

What am I missing?

Am I really the only one wanting to do this or am I asking a stupid question?
