Burt P wrt https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1752053/comments/43, you might try this:

edit /etc/default/grub, editing:

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to:

  GRUB_CMDLINE_LINUX_DEFAULT=""

And adding:

  GRUB_GFXMODE=1920x1080-32,auto
  GRUB_GFXPAYLOAD_LINUX=keep

(you will almost certainly need to change the GRUB_GFXMODE value if your main display is not native 1920x1080)

Then rerun sudo grub-mkconfig -o /boot/grub/grub.cfg.

I had the same symptom you did a while back, because for unknown reasons the hardware would get into a snit if the grub graphics mode didn't match the native mode. You may not need to comment out the splash and quiet, but I needed to in order to be able to successfully enter a decryption passphrase.
