   .. method:: get() -> ~gi.repository.Gdk.DisplayManager

      Gets the singleton ``GdkDisplayManager`` object.

      When called for the first time, this function consults the

      with multiple backends).

      Applications can use :obj:`~gi.repository.Gdk.set_allowed_backends` to limit what
      backends will be used.
