sounds like a headless system should have no display or UI components
whatsoever ("Thrown when code that is dependent on a keyboard, display, or
mouse is called in an environment that does not support a keyboard, display,
or mouse"). i'm curious how tcpmon could possibly work without display....
also i thought if something like 'xclock' works then you wouldn't have to run
in headless mode... ??
