Public bug reported:
On a Dell Sputnik (XPS13, second generation), an accidental upgrade to
13.04 caused my DisplayPort external monitor to stop working. This is an
Intel i915 adapter. Rebooting and re-plugging the display in various
combinations hasn't helped; and neither does detect displays in gnome-
control-center. Xrandr shows the external display as unconnected, and
doesn't recognize any external modes for it. I think this could be
related to #1165965. I've attached my xorg log; nothing immediately
obvious stands out, except that it thinks DP1 is disconnected.
