Thanks! Starting to get a feel for how some of this works.
Between the two responses I got I was abe to figure out what to do in my
situation.
To make things easier I built a cheap and dirty script that did the display

BTW where is the xhost stuff stored? I have not rebooted yet will my addition of
the local ip to the allowed access list survive a reboot?
Thanks again.
