Is there a clean way to determine if a possible setting for the DISPLAY
environment variable is valid? It's easy to check the output of ps for
instances of X, but how can we find which display those X servers are
serving?
Thanks for any help!

netstat -l (+ any other appropriate parms for your situation) will list
apps listening on tcp port 6000+ and unix domain /tmp/.X11-unix/X0 +
