I've just done some further testing. The behaviour varies depending on whether I use the displayport or vga connections.

Laptop Panel + VGA = With both on, the picture is perfect and I can move windows from one to the other.

NO Laptop Panel, Just VGA = I am able to disable the onboard laptop screen and just have the external monitor, however the external display is corrupted.

Displayport connectivity behaves as described previously mentioned, i.e. still completely blank when attempting to disable laptop screen, but fine if both are allowed to display.

I have also verified that the same behaviour is exhibited under Fedora 16 Alpha LiveCD. Will raise upstream and Fedora Bugs.
