[kubuntu] Dual Monitors separate X sessions?

Anyone here know how to create a separate X session in ubuntu 16.04 so that I can use one monitor to work on, and the other to watch something eles. Without the second monitor changing virtual desktops while I change them on the first display? I used to be able to do this in 12.04, but now the nvidia-settings control display is undefined and I have no clue how to us it.

Here is my hardware if you need it.
