Hi Steve,

Here are the results of some more tests. You may find them interesting.

When booting in failsafe mode (i.e. without graphical activation),
everything works fine. I'm able to use VC and the poweroff works
correctly.

So I proceeded to remove the nvidia drivers. When Using OSS modules, I
get the VC back, poweroff works fine, switching user also works and the
laptop suspends correctly.

So I have rebooted on my second disk (standard install from Ubiquity
without full disk encryption). I can confirm that everything works fine,
even with the nvidia module :

# jockey-text -l
xorg:nvidia_current - NVIDIA accelerated graphics driver (Proprietary, Enabled, In use)
xorg:nvidia_current_updates - NVIDIA accelerated graphics driver (post-release updates) (Proprietary, Disabled, Not in use)

The following apport-collect was done on the second install in case you
need it for comparaison.

Let me know how I can help.

** Description changed:

  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

Title:
  Encrypted installs break many functionalities - suspend, virtual

  Incomplete
