I'm afraid this doesn't quite do it.

It corrects the mistake of detecting DVI (see log).

But I still don't get dual screens, it still drops the internal LCD
screen and I end up with one screen, mirroed.  That happens both with
the fresh xorg.conf and with the xorg.conf that worked before with
just the new option put in.

Any ideas? Maybe I just overlooked some config option for a changed

conf/log/backported-patch here:

I also noticed that the Xv extension on the VGA output is not
functional in that mirrored mode.  The LCD displays the video picture
but the VGA has a blue window.  This might be normal.
