Outputs certainly *appear* to be detected. What makes you say they're not?

I assume you have a 1920x1080 screen hooked up to the DVI?

You can look at the KMS status in /sys/class/drm/ -- you should see
cardN-DVI-I-N  directories. xrandr should also provide accurate status, e.g.:

$ grep . /sys/class/drm/card*-*/status 
/sys/class/drm/card0-DVI-I-1/status:connected
/sys/class/drm/card0-DVI-I-2/status:disconnected

However it may end up being hidden due to vgaswitcheroo -- so make sure to look
into that too. (Unfortunately I know next to nothing about vgaswitcheroo, but
I'm sure Google knows more.)
