I haven't been able to get this to work at all. Below is the output of
xrandr --verbose. Note that there does not seem to be correct detection of
the outputs; "default" should really be something like "DVI". Then, things
like "xrandr --output default --pos -60" just don't work.

I tried generating a new ModeLine with cvt and/or copying it from the
Xorg.0.log file, and adding it to xorg.conf... but it's either being
ignored or not working. Any changes to the hsyncstart and hsyncend
parameters have no effect.
So, any more ideas? :-P
