Unless I'm misunderstanding, you have one connected display - you want to 
configure just that display. XRandR tells you which outputs are connected 
(exposed in the xrandr utility as "connected", "unknown" or "disconnected"), 
so your script can look for a connected connector, and let the user set that 
one up.
