This happens to my XMG/Clevo W230s with GM107M [GeForce GTX 860M]. I have an external monitor connected and disable the laptop screen with xrandr --output eDP-1-1 --off. When I suspend and close the lid, then disconnect the VGA cable and therefafter resuspend, Xorg crashes and I have to login again. It also kills screen sessions running in the background. This seems to be related to bug #1421808
