Title:
  Hang at login with nvidia proprietary driver and encrypted swap

Status in initramfs-tools package in Ubuntu:
  Incomplete
Status in plymouth package in Ubuntu:
  Confirmed

Bug description:
  Tested with initramfs-tools 0.130ubuntu3.1 and initramfs-tools
  0.130ubuntu3.2, both have the same bug. 0.130ubuntu3 works fine.

  Description:	Ubuntu 18.04 LTS
  Release:	18.04

  Reproed with nvidia-396 396.24.02-0ubuntu and the 390 package as well.

  System is using a nvidia 1050TI mobile. With prime-select to nvidia.

  My setup includes an encrypted home dir, and encrypted ram disk. Boot
  drive is an Nvme ssd.

  When installing the older working package I see this message:

  I: The initramfs will attempt to resume from /dev/dm-0
  I: (UUID=34e1ed83-dac8-400f-9a01-e21b9bb03dad)
  I: Set the RESUME variable to override this.

  I don't that that message from the broken packages.

  With the broken packages, once I login from gdm3, the computer
  freezes. I haven't been able to find a related error in the logs.

  Workarounds with the nvidia driver have included switching the prime-
  select to intel, swapping to the nouveau drivers, or booting with
  nvidia-drm.modeset=1 (which causes other issues in gnome, but does
  login to the desktop)

  Downgrading to initramfs-tools 0.130ubuntu3 solves the problem without
  needing to make and nvidia driver changes.

  Also removing `quite splash` from the boot options also solves the
  issue. So it appears the bug here is likely in plymouth.
