Hmm, it thinks it is disconnected. I wonder how the display showed the
boot sequence & grub screens if it is disconnected.

Title:
1002:9442 Monitor not detected via DisplayPort [Radeon HD 4850]
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I have a PowerColor AX4850 512MD3-DHO video card, a BenQ XL2420TX monitor,
and a Dell 3008WFP monitor.
I tried to connect the BenQ monitor with the DisplayPort connection.
This video driver did not recognize that there was anything plugged in.
Even if the BenQ was the only monitor connected, the OS driver found nothing.
WORKAROUND: The ATI binary BLOB did properly recognize this monitor
plugged in to the DisplayPort, but that driver is unusable for other
reasons.
I currently have this monitor connected via HDMI, but this connection
precludes the use of 120 hz refresh and 3D video.
