Bug description:
  
  In a university computer lab session we disable shutdown, restart, suspend, hibernate, switch user, and lock screen.
  Some are done with polkit (suspend, hibernate) and then the suspend menuitem is not shown on the session menu.
  Some are done with dconf e.g.

  # Show real name (and wider session menu as a result); lab also disable shutdown
  [com.canonical.indicator.session]
  show-real-name-on-panel=true
  suppress-logout-restart-shutdown=true
  suppress-restart-menuitem=true
  suppress-shutdown-menuitem=true
  user-show-menu=false

  # Quiet login screens
  [com.canonical.unity-greeter]
  play-ready-sound=false

  # Update-notifier
  [com.ubuntu.update-notifier]
  no-show-notifications=true

  # Software installation not possible for normal users
  [desktop.gnome.unity.lenses.applications]
  display-available-apps=false

  # Disable the lock screen & print-setup not on laptops, but in labs
  [org.gnome.desktop.lockdown]
  disable-lock-screen=true
  disable-print-setup=true
  disable-user-switching=true

  # Screensaver lockdown in labs
  [org.gnome.desktop.screensaver]
  lock-enabled=false
  user-switch-enabled=false

  # Logout prompt
  [org.gnome.SessionManager]
  logout-prompt=false

  This works fine except there is no value for suppress-lock-menuitem or
  suppress-switch-menuitem or suppress-lock-switch-menuitem, and the
  Lock/Switch User menuitem still appears; even though it is non-
  functional. Clicking on it blacks out the screen for a second and then
  shows the desktop again.
