That's as close as you can come with X operations.

True.  That is a misfeature in the Sun server, forced upon them by Sun
failing to provide any way for programs to sense what sort of monitor
the machine is connected to.  The server simply does not have any way
of determining whether it's connected to a 16", 19", or some other size
monitor...except for the user telling it, for which a flag is provided.
