Title:
  No luks password prompt - plymouth

Status in cryptsetup package in Ubuntu:
  Confirmed

Bug description:
  No luks password prompt - plymouth
  NON root LUKS block device encryption (no initram involved)

  Bug 1359689 Ubuntu or Red Hat(!) Bugzilla – Bug 1086972 are still valid. 
  With Ubuntu 17.10 in November 2017 the problem remains:
  It is a Plymouth issue, not an issue of LUKS or NVIDIA or Linux-distro.

  Issue: I have an encrypted non-root-partition (actually /home) and the
  whole lifecycle of booting, working, closing works flawless. Boot and
  LUKS will handle the process based on crypttab and fstab, no entry in
  inittab. Follows the (correct) specs and works well.

  Except the password request.

  Plymouth swallows the password request.

  Here we do NOT talk about the initram issue - this is a slightly
  different situation, same bug. So solutions for similar cases do not
  work here.

  Reproducible you can try to guess when the request should be there,
  manually enter the matching password and the mounting goes on well.

  Reproducible, when you prematurely press "enter" during(!) the
  checking step the displayed lines shift up (and display an empty
  line). The password request becomes visible in this empty line after
  finalised checking procedure. Could probably be circumvented by adding
  more newline characters, it seems.

  So it is clearly a display issue caused by Plymouth.

  The request for password is fired up correctly. It is just not visible
  to the user.

  I do not have a NVIDIA in the machines I implemented it in. It's
  happening on laptop with Intel graphics as well as on a desktop with
  A10 APU graphics.

  Graphics card does not matter at all.

  I do NOT use the graphical / picture grub screen, rcS has extended
  verbosity.
