[Bug 993864] Re: Encrypted installs break many functionalities - suspend, virtual console, switch user

[Louis Bouchard]

Hi Steve,

just tested without the 'splash' (and quiet) boot params. I get the same
behavior : ALT-F1 gets me to a blank screen, unable to ALT-F7 back into
Unity.  Hardware poweroff (10 seconds on the power on button) is the
only way out of this.

FYI, I also noticed that the normal shutdown procedure never completes
and does not power off the laptop. Again, this is not the case on the
other disk, installed without full disk encryption.

Title:
  Encrypted installs break many functionalities - suspend, virtual
  console, switch user

Status in “plymouth” package in Ubuntu:
  Incomplete

Bug description:
  This seems to be a follow-up to LP: 942846.

  When using the alternate CD to install 12.04 with LVM + Full disk encryption, the resulting O/S has many problems :
   - Unable to switch to virtual consoles : Alt-F1 with hang the graphical output, requiring hardware reset
   - Cannot suspend (S3) : suspend will trigger but will result in a hung system and blank screen
   - Switching user hangs on a blank screen

  As outlined in LP: 942846, just after grub, the screen systematically displays :
    error: no video mode activated

  The screen will then switch to text mode, then ask for the LUKS
  password (picture attached)

  Comment #6 in LP: 942846 indicates specificities with plymouth when
  used in conjunction with LUKS.

  It is important to know that the same laptop (HP Elitebook 8440p)
  installed with the standard CD (ubiquity) without LUKS encryption on a
  separate disk DOES NOT show those problems. Both environments are
  still available.

  apport-collect -p plymouth {BUG} will be provided for this bug shortly
