xorg.conf for 4 NVIDIA GTX1080i GPU, fake monitor, headless arrangement

xorg.conf

# Use this in a situation where you want a headless Linux box with multiple GPU boards but no desktop environment
# Fake EDID convinces drivers that a monitor is connected
# Use any EDID binary file
# To start a fake X server make a systemd file with something like:
# ExecStart=/usr/bin/tcsh -c 'xinit /opt/set-gpu-fans/setfanspeed.sh -- :0 -once -config /opt/set-gpu-fans/xorg.rob'
# See other gist for fan setting script : https://gist.github.com/RobDeBagel/a960c2b157256c162220e60300529cf0
