This is what I thought of doing, however, I haven't managed to find a way to retrieve the EDID of the screen.
Is this in the README ?
Also, interestingly, with the newer nvidia kernel, for the 1st x11 adapter, I have to specify:
ConnectedMonitor DFP,CRT ; even though I am not using TwinView
if I want something displayed on the VGA screen. I didn't have to do that before.
Each adapter had its own ConnectedMonitor option
