Actually since 4.6 (or 4.4) the 'Display' settings applet has taken over
doing the xrandr stuff.  However at that point there
was /etc/.config/xfce/monitor.xml which and a <clone> tag which could
be <clone>no</clone> (or off, can't remember), which would result in
the two monitors being separate (without that the smallest monitor is
mirrored on the larger monitor, so you effectively have one monitor,
just displayed twice).  Unfortunately in the 4.8 the clone option was
removed and I don't know how to tell xfce to not mirror the displays
(mirroring is the default, unless you use xrandr to tell it not to
mirror).  Also, the Display applet settings are now applied after the
/etc/.config/autostart stuff, so it doesn't work to do what I used to
do, which is have and xrandr script in autostart.

Basically 4.6 was doing the right thing, and it's broken now because
there is no way to not mirror automatically (though once initialization
is complete I can manually do xrandr and separate the outputs so they
are different displays (independent) rather than mirrored (the default).

Daniel
