.... some progress!

If I disconnect the DVI-D lead to my monitor and use an analogue VGA
connection instead I get a working system!  However the resolution
isn't as high as I would like and the display quality isn't as good as
with the DVI-D connection (when it worked).

So, it is *something* to do with the DVI-D recognition and configuration.

Any ideas anyone?
