[Bug 1016170] Re: No login screen unless "quiet splash" removed from boot line

[Colin Watson]

It may be worth putting 'set debug=all' at the top of grub.cfg and
seeing how far it gets.  (Warning: this can potentially take a *long*
time to boot.  In extremis you might even need to boot from a live CD or
similar to remove it.)

** Package changed: grub (Ubuntu) => grub2 (Ubuntu)

Title:
  No login screen unless "quiet splash" removed from boot line

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  I'm not entirely sure this is a Plymouth bug, but here is what's going
  on.

  MacBook Pro 1,1 running latest Quantal.

  This machine was running 12.04 just fine, then I upgraded it to 12.10.
  Now, whenever I boot it, I just end up with a black screen, no login
  screen, no apparent cursor, no response to keyboard.

  If, at the grub screen, I edit the boot line and remove "quiet
  splash", the machine boots to its login screen, although it sometimes
  takes quite a long time.  I don't see much on the console output that
  indicates what's going on though.
