Comment 13 for bug 150930

Markus Korn had a similar issue with Ubuntu Desktop amd64 (20071016).
In his case the uplash.conf xres and yres are empty then his screen goes off at boot time and he's unable to see anything till X started (unable to do the check CD for example).

Hardware is a Geforce 8600GT and a VGA screen (trough a DVI->VGA adapter).
