[Bug 966403] Re: Lubuntu Install (entire disk with encryption) doesn't prompt for disk password.

[Steve Langasek]

Thanks, that confirms that this isn't a bug with the lubuntu theme;
which means it's a hardware-specific bug instead.

Can you please boot with the option 'plymouth:debug=/var/log/plymouth-
debug.log' added to the kernel commandline, and attach the resulting
file?

Title:
  Lubuntu Install (entire disk with encryption) doesn't prompt for disk
  password.

Status in “plymouth” package in Ubuntu:
  Incomplete

Bug description:
  When installing the lubuntu image as part of the iso testing
  (lubuntu/daily/20120327/precise-alternate-amd64.iso) using the
  alternate installer from the daily builds for March 27, 2012, I
  attemted to make a full-disk encrypted setup using LVM.  I used the
  instructions from the isotesting testcase:
  http://testcases.qa.ubuntu.com/Install/AlternateEncryptedLvm

  The install went perfectly.  However, when I rebooted, the system hung
  on a blank screen.  I left it for over half an hour, and no response.
  At this point, I simply typed in the password for the LVM encryption,
  and the system then continuted to boot normally.

  After getting into the system, I tested it (everything was working
  fine) then rebooted.  I experienced the same symptoms (just a blank
  screen) after each boot.

  I believe that there is supposed to be a screen prompting the user for the password for the LVM encryption instead of just a blank screen.
