Actually with linux twinview is exactly how it should be setup. He should also be using:
Option "NoTwinViewXineramaInfo" "1"
Which makes it show the OS thinks its only a single monitor or if using multiple monitors use:
Option "TwinViewXineramaInfoOverride" "XXXXXXXXX"
To set manual dimensions of the monitor seams if using multiple MST displays which AFAIK can't be done in windows right now due to the driver hacks it does to do the spanning in the first place.
Thanks, I wonder if you can help me get this setup. I've updated to trusty and I've got v331 of the nvidia drivers up from 313 where I was.
I still have the dual screens. Below is my x config. I think I need to fix the metamodes but unsure how best to do that based off a few searches.
Code:
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "Stereo" "0"
Option "NoTwinViewXineramaInfo" "1"
# Option "nvidiaXineramaInfoOrder" "DFP-4.8"
Option "metamodes" "DP-1.8: nvidia-auto-select +1920+0, DP-1.9: nvidia-auto-select +0+0"
Option "SLI" "Off"
Option "MultiGPU" "Off"
Option "BaseMosaic" "off"
SubSection "Display"
Depth 24
EndSubSection
