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.
