Section "Device"
#	Identifier	"nvidia"
#	Driver		"nvidia"
#	^ this should be somewhere in the xorg.conf already, the value for
#	identifier might vary though.
#	There should be 2 device sections but only one with nvidia as "Driver" value,
#	this is the one where you should put the following lines.
	Option		"ConnectedMonitor" "DFP-0"
       	Option		"CustomEDID" "CRT-0:/sys/class/drm/card0-LVDS-1/edid"
	Option		"IgnoreEDID" "false"
	Option		"UseEDID" "true"
