I think I have the same issue.
Difference is that everything worked as charm until I've updated some non-nvidia packages. Since then I'm stuck to uning nouveau as none of the workarounds worked.
i.e. grub was updated from 2.02-2ubuntu8.1 to 2.02-2ubuntu8.2.
Not sure if any of these can help, but for me nvidia has been completely broken since this update. Since then I'm constantly getting the following lines in kern.log (egrep -i '(nvidia|nvrm)'):

HW:
ROG STRIX GL503VM-FY022
nVIDIA GeForce GTX 1060 6GB
What worked fine before update:
kernel 4.15.x-x with nvidia 390 (ubuntu repository)
kernel 4.17.x with nvidia 396 (ppa)
After the update it worked one more time with 4.15.x with d/xxxx. conf
options nvidia_390_drm modeset=1
in /etc/modprobe.
Since after next reboot nothing has worked except purge-ing nvidia and switching to nouveau...
Attaching apt log for that update. mono was updated as well adding a lot of noise, but the relevant part seems to be grub:
