Probably the kernel has the connectors mixed up.  My monitor is
connected via DVI, but the kernel thinks otherwise:

,----
| $ cat /sys/class/drm/card0-DVI-I-1/enabled
| disabled
| $ cat /sys/class/drm/card0-VGA-1/enabled  
| enabled
`----

Naturally, xrandr reports the same false information.

Indeed.
