I'm able to set laptop monitor as primary which disables external monitor (and vice-versa) I was using fglrx without problems however after fglrx support dropped in recent Ubuntu update I was forced to return to xorg driver. Tried manual switch to mainline Linux 4.5 kernel, same thing. Tested on 14.04, 15.10, 16.04 with same results.
