192 * need the device-manager to exist early on.
193 *
194 * To be consistent with other clutter backends though we only associate the
195 * device manager with the backend when _clutter_events_wayland_init() is
196 * called in _clutter_backend_init_events(). This should still allow the
197 * runtime selection of an alternative input backend if desired and in that
198 * case the wayland device manager will be benign.
199 *
200 * FIXME: At some point we could perhaps collapse the
201 * _clutter_backend_post_parse(), and _clutter_backend_init_events()
202 * functions into one called something like _clutter_backend_init() which
203 * would allow the real backend to manage the precise order of
204 * initialization.
