[Bug 1030094] Re: LVM encrypted, screen turned off after grub

[Steve Langasek]

Copied over the ProcFB setting from that other bug, then; it's
*possible* that there's a bug preventing the fb driver from loading and
that this is the problem you're seeing, but I think this is unlikely.
The lspci certainly shows that the nouveau driver is loaded.

What we can't easily see from this bug report is what plymouth themes
are configured / in use.  Any of this information that you can get
manually from the install in question would be helpful.

In bug #1042225, Felix Geyer suggests that his bug might be a duplicate
of this one.  When you hit the black screen on boot, can you confirm
whether hitting Esc brings up the text prompt, and whether hitting it a
second time brings up the splash screen?

** Description changed:

  Hallo
  Not reproducible in VM.
  Testing Ubuntu server mad64 20120727 and 20120817.1:
  Performing an installation of lvm encryption at the reboot the screen is switched off just after grub.
  To have the system working we need to remove, from the boot line, the splash entry.
  Doing so we will have the passphrase request in a black screen.
  If instead we remove the vt_handoff entry the splashscreen will be shown, but the passphrase request will appear in a bad position at the center of the screen on a background purple with Ubuntu 12.10 written.
  Thanks
