Unless the user need to interact with clients started from the script,
running Xvnc is likely to be preferable to running a "real" X server. 
If there's a reason to avoid Xvnc, try Xvfb instead.

Running a real X server requires that the system has video hardware,
that you have the necessary permissions to use it, and (if you want to
run more concurrent X servers than you have video cards), that the
hardware (and its driver) is capable of sharing the card between
multiple X servers.
