Default Re: Ad-hoc second monitor problem

I have set a driver option:

Option "TwinViewXineramaInfoOrder" "DFP-0"

and with this settings switching off TwinView leads me to either crash or blank screen.

Surprisingly, now it worked fine (!).

What confuses me - when I want to switch TwinView, it actually switches off the screen, which is currently highlighted - how can I force DFP-0 to be always on and always a primary screen regardless what I attach to the external monitor's port?
