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

[Barry Warsaw]

I do think the "works half the time" behavior of grub safe boot is
coming into play.  It's not exactly half the time but whenever I get a
hang, I definitely get the grub screen afterward.  Occasionally I get
the grub screen more than once in a row though.

I downgraded libplymouth2 plymouth plymouth-theme-ubuntu-logo plymouth-
theme-ubuntu-text and plymouth-label (the only installed *plymouth*
packages).

It still hangs about half the time.

Probably not relevant, but reported here for completeness.  I got these
warnings at the end of the downgrade.

cryptsetup: WARNING: failed to detect canonical device of /dev/sda3
cryptsetup: WARNING: could not determine root device from /etc/fstab

(FWIW, I re-updated to keep the number of variables low).

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

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.
