The xdg_session_manager_v1 global interface is the generator of xdg_session_v1 objects for clients. These will notify of an unique ID that can be used for future instantiations. Once a xdg_session_v1 object is obtained, toplevels can be added to be managed by it, and clients may get a hint about whether the toplevel was restored to a saved state. Changes by Carlos Garnacho: Integrate with MetaSessionManager core object. Flesh out event emission of xdg_session_v1 and xdg_toplevel_session_v1 objects, handle sessions being replaced/deleted. Changes by Sebastian Wick: * make lifetimes of xdg_sessions entirely determined by the wayland and handle its destruction via the signal * fix session destruction vs deletion * do not drop refcount of replaced session state temporarily to make sure the replacing session keeps the state * disconnect signals of destroyed and replaced sessions * disconnect window-unmanaging signal handler for MetaWaylandXdgToplevelSession * call wl_resource_destroy in xdg_toplevel_session_remove to make it a destructor * handle session being destroyed before topevel-sessions * handle the toplevel going away before the topevel-sessions Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3825> |

Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork of Clutter, a scene graph and user interface toolkit.
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
