Don't see it crashing X11 session here at all, 17.10 -
$ echo $DESKTOP_SESSION
ubuntu
sudo cat /sys/module/nvidia_drm/parameters/modeset
Y
(- But the disappointing thing is this -
$ xrandr --verbose

PRIME Synchronization: 0
supported: 0, 1
So currently -
no nvidia support in gdm3/wayland
nvidia support in gdm3/xserver-xorg but no PRIME Synchronization support.
i.e., a complete fail in Ubuntu all around
