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

[Moritz Naumann]

Looks like this made it into 12.10. In my case it IS a duplicate of
#1042225 and hitting escape once for the textual and twice for the
graphical FDE password prompt works for me. I've upgraded from 12.04
(and before this I've been following stable releases). Removing the VT
handoff option off the kernel line at boot makes the graphical prompt
appear without screen blanking / the display switching to power saving /
standby mode.

If you need more details please let me know.

Title:
  LVM encrypted, screen turned off after grub

Status in “plymouth” package in Ubuntu:
  Confirmed

Bug description:
  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
  Fabio
