Thanks for the website. I have been able to get further along. This is
my current xorg.conf. X comes up with the proper modes on each monitor
but my desktop is on the VGA monitor and half on the LVDS. I would like
the desktop to be on the LVDS alone with the vga just empty where I can
drag windows on.
