Public bug reported:
When booting with the default enabled kernel mode-setting, there is no
signal on the DVI port. The VGA port works. The DVI port works when the
'nomodeset' kernel parameter is used. This is an Apple Mac Mini with an
integrated DVI/VGA port if that makes any difference.
I attach an Xorg.*.log corresponding to kernel mode-setting being used
and one where 'nomodeset' was used.
