I've now carried out a test using twm and a xterm. Initially, both
monitors display the same image with the mouse bounded at all four
screen edges.

Running 'xrandr --verbose --output DVI-I_2/digital --right-of
DVI-I_1/digital' I get the following output (with 'Virtual' line in
xorg.conf):

screen 0: 3360x1050 947x296 mm  90.10dpi
crtc 1:    1680x1050   60.0 +1680+0 "DVI-I_2/digital"

Now the monitors are still in clone mode, but show the "right half" of
the desktop - mouse is bounded on the top, bottom and right but can be
moved off screen to the left. This is the same behaviour I experienced
when testing with GNOME.

Running the same command with the 'Virtual' line commented out, I get:

xrandr: screen cannot be larger than 1680x1680 (desired size 3360x1050)

The screen appearance is unchanged from the initial state.

Should I be expecting a second crtc entry in the output from xrandr
above?

Cheers,
