Dual head configuration was enabled in gnome-control-center (1:2.22.1-0ubuntu2).
There is still an issue where Virtual size must be specified in xorg.conf, but that's an xorg bug, not gnome-control-center.
Marius, regarding your need to explicitly turn on the external monitor, I've not reproduced that behavior myself so it sounds like a separate bug, not particular to dual-head configs; please file a new bug with additional information if you think it needs further investigation.
