Graphics port hardware detection

[pdouglass]

In the database we have a flag for "DVI only". This is manually set.

LCRS should set the parameter. Further, the database should be revised, so that all modern video interfaces are cataloged: Display Port (and Mini Display), HDMI. And What about PCs without VGA? Video output should be a multi-selectable list.

Can you advice how to detect "DVI only" ? It would seem maybe something we could do through xrandr but the horrible circus of getting X.org + all available gfx drivers compiled into the embedded Linux kernel makes me think otherwise.
