The old KDE3 module contained a "screen" droplist for configuring
individual monitors--has this changed?  (I only have single-monitor
systems available right now.)

Another option, if and only if your computer's video card uses an
nVidia chipset, is to install the manufacturer's proprietary driver module
and configuration utility, which offers extended support.  I don't know
if AMD offers an equivalent.  Intel almost certainly doesn't.
