Well, that's not exactly what I'm seeing. In this case we had two monitors
with two pcs. The teacher installed the main and thin client server on
both pcs with their respective monitors. In both cases, the server
installer worked and detected the monitor settings. He then hooked up the
other pc as a thin client and the monitor wasn't detected (in both cases).
He tried booting the thin client with both monitors to no avail. We used
the frequency settings from the server XF86Config-4 for the client ltsp
setup.
It seems to me that this is a software problem. Perhaps I have missed
something.

Well, if there is a set of safe defaults which I could document that would
be great. I don't mind saying "register mac address for static ip; create
new host in ltsp; set hsync to "XX-YY" and vrefresh to "AA-BB" but I don't
want it to begin with "determine the monitors vrefresh and hsync ranges"
which is a little non-trivial. I don't want to write a doc which sometimes
breaks monitors though!
Unfortunately the funding for schools' IT equipment here is close to
non-existent so people generally would be using old donated equipment.
This monitor problem is a real killer for a person inexperienced with X (ie
most school teachers).
