Creating a new Xscreen using nvidia xconfig causes screen to go blank (with or without xinerama) on

I need two xscreens on a dual display with ubuntu 16.04 and gtx 680. Unfortunately, when I try to create a new xscreen with nivdia xserver settings utility the screen with the new xscreen is rendered blank. I can get the xorg.conf if needed but I was wondering if this is a known issue.

I am using the 367.27 driver version.
