[Bug 967229] Re: Text mode shown briefly with various "cryptic" texts when logging out or shutting down

[Steve Langasek]

James, the vt definitely needs to be cleared after plymouth exits (i.e.,
after lightdm starts up), not before, in order to avoid races.  Brian
Murray has been looking into this; Brian, any further progress?

First, there's no such facility in upstart.

Second, it doesn't change the fact that any other jobs that are /already
stopping/ at the time lightdm stops may generate output.

  Text mode shown briefly with various "cryptic" texts when logging out
  or shutting down

Bug description:
  Text mode hits in for about a half a second every time one logs out or
  shuts down the computer.

  The attached video "Text-mode in logout and shutdown.webm" is a
  combination of two clips showing this on one of my computers. This one
  has slightly more text output than my other machines, but on every
  machine it catches attention by being ugly and I'd guess "cryptic" or
  suspicious for ordinary people in the otherwise smooth experience
  starting from the bootup ubuntu logo.

  Tested on up-to-date Ubuntu 12.04 on an Intel IGD graphics netbook,
  Intel Sandy Bridge laptop and Radeon HD 4670 (open drivers) desktop
  machine. The video is from the sandy bridge one.

  xorg is most certainly wrong but that what ubuntu-bug got me for
  reporting "screen corruption" :) Might be plymouth, might be lightdm?
