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

[Barry Warsaw]

I got the opportunity to show Colin the behavior in person, and he had a
key insight.  He asked whether the freeze happens on the reboot after a
shutdown, as opposed to an explicit reboot command (e.g. choosing Reboot
from the greeter menu).

In my very limited testing so far, it seems to be true that a
shutdown->boot does not freeze, while an explicit-reboot does freeze.
I'll have to test a few more times to verify, but this is consistent
with the previously observed behavior because obviously after a freeze
is observed, leaning on the power button results in a successful boot.

Colin suggests looking at reboot quirks and fiddling with the reboot
parameters to see if something's changed or if there is a workaround.  A
quick google didn't find anything immediately relevant, but I may do
some more (very) background investigation.  OTOH, this machine is fairly
old and the h/w is mostly limping along as it is, so I'm not
particularly motivated to spend much more time on this.

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.
