Title:
  cannot unlock LUKS devices / video mode not activated

Status in “cryptsetup” package in Ubuntu:
  Invalid
Status in “grub2” package in Ubuntu:
  New
Status in “plymouth” package in Ubuntu:
  Incomplete
Status in “ubiquity” package in Ubuntu:
  Invalid

Bug description:
  reproducible with ubiquity or alternate installer in KVM virtual machine:
  1) select lvm + encrypted instalation

  
  it fails to boot, in a way that I get "no video mode activated" and I cannot type the password in to unlock the drive.

  As a workaround, I had to:
  1) force reboot machine
  2) then grub options come up
  3) select recovery mode
  4) then I can enter the password using text interface
  5) resume normal boot

  Disabling splash, brings up text interface to unlock the drive &
  allows to boot.
