Quadro 600 Linux force video output

Graphics / Linux Linux
1

I have opensuse 42.1 x64 with lastest nvidia drivers and dual-monitor setup. I want to force video output, so linux won’t detect monitor disonnect. I managed to do it on windows using edid files, and now when i disconnect one of my monitors, desktop isn’t resized and windows thinks that monitor is still connected. I need to have something like this on linux. I tried adding edid files in xorg.conf by adding ’ Option “CustomEDID” “DFP-0: /etc/X11/benq.bin; DFP-1: /etc/X11/hp.bin” ', but it still resize my desktop after monitor disconnect. How can i make it work? Here is my full xorg.conf:
