    longDescription = ''
      light-locker is a simple locker (forked from gnome-screensaver) that aims to have simple, sane, secure defaults and be well integrated with the desktop while not carrying any desktop-specific dependencies.
      It relies on lightdm for locking and unlocking your session via ConsoleKit/UPower or logind/systemd.
