That makes sense.  Having a "detect displays" button like OS X has
works ok too.

Thanks!  With some experimentation and Googling I even managed to get
dual-screen working pretty well.  (I had edit the "Virtual" Display size
in xorg.conf, which is clunky.)  Perhaps for F8 we'll have a nice
GUI interface for managing multiple displays, but for now this works.
