Title:
  unity lock screen provides no way to force-logout a user

Status in Unity:
  Triaged
Status in unity package in Ubuntu:
  Confirmed

Bug description:
  Let me start by saying that I realize that unity's screen locker is
  not the same thing as gnome-screensaver.  That having been said, there
  are major regressions in functionality with the advent of Trusty.
  Virtually every site that uses Linux in any sort of public computing
  areas makes use (or used to, at least) of gnome-screensaver's "logout-
  delay" and "logout-enabled" functionality, which would, after the
  screen had been locked for a pre-determined amount of time, present a
  "Log Out" button that would end the user's session, optionally running
  a custom command to do so.  This is vital, lest people walk away from
  their workstations, rendering them unusable by others until they are
  rebooted.

  unity's lock screen mode provides no way to do this.  Right up until
  the final beta, it was possible to swap out unity's lockscreen mode
  for gnome-screensaver, but that was removed as well.  I wouldn't mind
  if it was possible to configure the alternate use of a screensaver,
  but Unity goes out of its way to ensure you can't do this.  If there's
  some magic way to do this, by adding an applet to the panel when in
  lockscreen mode, or by invoking some D-Bus black magic, I'd be happy
  to hear about it.

  But really, removing this level of functionality while simultaneously
  preventing any workarounds, is a real problem.

  Steps to reproduce:
  1) Log in to a unity session.
  2) Lock the screen.
  3) Observe that org.gnome.desktop.screensaver gsettings keys are not honored.
  4) Examine the com.canonical.unity* schemas and observe there is no way to enable this behavior.
