Binary package “mutter” in ubuntu lunar

Example window manager using GNOME's window manager library

 Mutter is a Wayland display server and X11 window manager and
 compositor library. 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.
 This package contains the mutter executable. It can be used as a
 standalone window manager, but is primarily intended for debugging.
