Problem with TwinView configuration

TwoThousandXX · 2018-03-20 19:04:47

Hi, today I decided to configure NVIDIA TwinView instead of Xinerama since RandR doesn't work with it, and well... After editing xorg.conf, the results aren't perfect. Instead of the desired results, my second monitor is just mirroring the image of the first at lower resolution.
NVIDIA driver version is 390.42, the GPU in question where the monitors are connected is an NVIDIA GTX660, the first monitor, plugged into the HDMI port (HDMI-0), is an HP w2207h running at 1680x1050, and the second, plugged into the DVI-I port (DVI-I-0, as stated by nvidia-settings), is an AOC e950 running at 1366x768.
Here are the contents of /etc/X11/xorg.conf

Ditch the rubbish config file and just configure your screen layouts using either nvidia-settings (do NOT write an xorg config, it should be able to restore things) or xrandr (at runtime, via xinitrc or whatever) or some monitor configlet:

/etc/X11/xorg.conf.d/11-monitor.conf

Section "Monitor"
	Identifier "DVI-I-0"
	Option "RightOf" "HDMI-0"
	Option	"Enable"	"True"
# more options here?
EndSection

Section "Monitor"
	Identifier "HDMI-0"
	Option	"Enable"	"True"
# more options here?
EndSection
