I'm having issues getting my triple-monitor setup to work - I've struggled to get the desktop to span all 3 monitors and even now, Cinnamon crashes at startup and runs in fallback/failsafe mode. I'm hoping you wonderful people might be able to explain a few things and (most likely) point out the glaring error I feel I must have made somewhere in the config.
My system is:
Mint 17.3 64-bit
Kernel 3.19.0-32-generic
CPU is i7-8700k 8th gen @ 3.7GHz / 6-core
48Gb RAM
Graphics cards are both Nvidia Quadro K620 / GM107GL
PSU is a healthy 750W unit
Motherboard is Gigabyte Z370 AORUS Ultra
NVIDIA X Server Settings GUI reports:
Nvidia driver version 384.111
Server Version: 11.0
Server Vendor Version 1.17.1
NV-Control version: 1.29
My xorg.conf looks like this:

[ 20.666870] cinnamon[2642]: segfault at 0 ip (null) sp 00007ffdcf5928b8 error 14Nvidia X-Server Settings GUI recognises both GPU's and all 3 monitors. Cinnamon crashes at startup, Ctrl+F2 drops it into fail-safe mode. I then have a single X Screen spanning across all 3 monitors, which is what I want and took a lot of fiddling to arrive at.
Can anyone point me in the right direction?
