well there is no DVI or VGA port, it is DisplayLink USB graphics, and
there are two drivers: udlfb and udl-drm (udl.ko). the udlfb one is
stabler. When you have successfully loaded udlfb the display should turn
bright green, and if you use udevadm you should be able to figure out
which /dev/fb[0-9]* it is.
