[Launchpad Bug Tracker <854329@xxxxxxxxxxxxxxxxxx>]

This bug was fixed in the package kde-workspace - 4:4.7.1-0ubuntu3

---------------
kde-workspace (4:4.7.1-0ubuntu3) oneiric; urgency=low

  * Update debian/kdm.upstart to match latest gdm.upstart improvements:
    - Also export LC_MESSAGES with the rest of locale information
    - When kdm is shut down by a runlevel call, emit an upstart event that can
      be caught by plymouth so it can distinguish between the DM shutting down
      for a runlevel change vs. other causes (LP: #854329)
  * Update patches for post-4.7.1 changes.  Add to debian/patches:

Bug description:
  the migration from gdm to lightdm has revealed a race condition in
  /etc/init/plymouth.conf on shutdown.  The job currently does:

   start on (... or (runlevel [016] and (stopped gdm or stopped kdm or
  stopped $otherdm)))

  However, if more than one of these dm packages is installed, at least
  one of these 'stopped $dm' events will be emitted *on system startup*
  because whichever DM is not the default will have its job started and
  immediately stopped.

  This means the second half of the AND is already satisfied, so as soon
  as the 'runlevel' event fires, plymouth starts up, racing the shutdown
  of the actually-running DM.  And starting plymouth is bound to be
  faster than shutting down a running X session, which means plymouth
  and X are running at the same time and arguing about who controls the
  VT.

  The result is that plymouth starts rendering, then X sets the VT into
  text mode on shutdown, causing plymouth's progress indicator (5
  cycling dots) to be drawn over the text screen.

  To fix this, we need the plymouth job to be able to distinguish
  between the *cause* of the DM job stopping.  This probably means
  emitting a new event from the DM jobs, having plymouth look for this
  new event, and coordinating the transition with bidirectional Breaks:
  on the packages.
