Unsure if it's related, I've closed laptop cover twice in order to test
the delay of login window, reviewed syslog which prints:

Title:
  Lightdm needs a long time to display its greeter after resuming from
  suspend.

Status in “lightdm” package in Ubuntu:
  Confirmed

Bug description:
  Meanwhile only a cursor is visible but "enter password to unlock" window accepts keyboard input so it is actually active in background just isn't displayed. Maybe some GTK issue?
  BTW it worked fine on alpha 2.
