A number of monitors are supported using the DisplayLink driver, for
which there is an open-source version -- see
http://libdlo.freedesktop.org/wiki/.

There's also a (probably non-exhaustive) list at the top of
usbtouchscreen.c:

Some of these are even affordable.

There are also some proprietary drivers out there.

I haven't used any of these personally, but I've seen them in use -- so
I know it can be done.
