Public bug reported:

Binary package hint: xorg

When I insert my Dell M2300 laptop in a Dell docking station, I get the
initial Ubuntu boot screen on the external monitor that is connected to
the docking station but when X starts the external monitor goes blank.

My solution was to add the following line to the Device section in
/etc/X11/xorg.conf:

        Option  "UseDisplayDevice"      "DFP-1"

Xorg should recognize the docking station and the external monitor
attached through it and add the option above to xorg.conf before
starting.
