Multiple screens can only be setup via xorg.conf. randr and kcontrol operate inside screen level.

Synopsis
xrandr ... [--screen snum] ...
--screen snum This option selects which screen to manipulate. Note this refers to the X screen abstraction, not the monitor (or output)....
It can manipulate properties of stuff INSIDE the screen, it cannot manipulate screen layout itself - add, remove, change positions, move outputs.
