This isn't going to work until we properly support external displayport
bridge devices. This also won't work until display port is functional.
Sorry :-(
Card -> DisplayPort -> internal DP to VGA converter (NUTMEG) -> VGA ->
Monitor
Getting to your display is a long and complex journey if you see TRAVIS or
NUTMEG.
Not all newer cards use DisplayPort bridge devices... but they are getting
a lot more common as cards move to being all digital. (Cards only
supporting digital outputs such as DisplayPort devices internally and
using cheap bridge devices to output video to legacy DVI, VGA, etc makes
sense, it's also a lot more complex :-))
