* Some hackery to get ConsoleKit to work with the SLIM and "auto"

Browse Source 
display managers.  This was broken due to a change in ConsoleKit
  0.4.2:

    https://bugs.freedesktop.org/show_bug.cgi?id=28377

  Using ConsoleKit's pam-ck-connector helps in that it creates local
  sessions; however, they're not marked as active because the
  x11-display-device property is not set.  As a workaround, calling
  ck-launch-session seems to work.

  More details:
