After some more research I found out that this is actually due to an
unimpelmented feature in Nvidia's drivers.
On this model of laptop, the video output ports all connect directly to

This bug is also occurring for me when installing nvidia-387 off

I also installed and booted 4.15-rc7 and attempted to install nvidia-387
and got another crash in the DKMS build process.
However I installed nvidia-384 (this would be the just-released 384.111)
on 4.13.0-26-generic and it works fine.
