Works fine on both ports here so that could also indicate a
(configuration) problem with your user space.
The port closes to the screen is the second port ("Unknown20-2", "USB-2"
or soon "DP-2"), which may or may not be relevant.

I don't use Gnome, but that sounds like it could be related to the
mutter issue Brian mentioned. Have your verified that you have that fix?
Try booting to a VT console (stop whatever display server you are using)
and then plug in the USB connector in order to confirm that the issue is
in user space. You should see the console mirrored on your external
display.
