[Bug 1721988] Re: Ubuntu 17.10 full disk encryption + Nvidia drivers not booting

[Aaron Von Gauss]

With Ubuntu 18.04 LTS or Ubuntu 18.10 and full disk encryption enabled,
after I install the nVidia drivers I also receive the blank screen
though I can type the passphrase in and it will continue to boot
successfully.  What seems odd based on some past comments is adding the
"nomodeset" parameter for me presents the splash screen as expected even
with the nVidia drivers installed.  I've tested this with both the 390
and 415 drivers.

Title:
  Ubuntu 17.10 full disk encryption + Nvidia drivers not booting

Status in plymouth package in Ubuntu:
  Confirmed

Bug description:
  I've installed ubuntu 17.10 with full disk encryption and then
  installed the nvidia drivers (v 384). when I boot the computer I will
  get the graphics interface to enter the encryption key but the system
  will stop to work, like it has hang. Basically I'm not able to enter
  the password!

  I've to restart in safe mode to be able to enter the password for the
  encryption, after that I can just resume the boot and all works.

  There seems to be some issues with the initial boot screen and nvidia
  drivers... I'm not able to press any combination of Control+Alt+Fx key
  to get any extra info about what is going on (not able to get any text
  mode).
