  Unlock screen shown twice (violet and black) after resume from sleep

Status in “lightdm” package in Ubuntu:

Bug description:
  After waking the computer from suspend, there is

  1. The screen saying: "This session is locked" / "You will be redirected ..." for about a second, followed by a split second of the framebuffer console.
  2. Violet login screen, where I am asked to type my password (which I do)
  3. Again shortly the "This session is locked" screen
  4. For about half a second, the desktop (in the state it was locked) appears on the screen
  5. Another login screen, black, asks me to type the password (which I do)
  6. The session appears and is usable afterwards.

  I expect the password prompt to be shown *at most* once, not twice, to
  unlock the session.

  This is a regression from saucy, where I was typing the password
  either once, or was even able to disable the lock in dconf/gconf
  (don't remember exactly where).
