Mutter is a window manager initially designed and implemented for the X Window System, but then evolved to be a Wayland compositor. It became the default window manager in GNOME 3, replacing Metacity[3] which used GTK+ for rendering.

Window manager

Mutter uses a graphics library called Clutter giving it OpenGL capability. Mutter is a portmanteau of Metacity and Clutter. Mutter can function as a standalone window manager for GNOME-like desktops and serves as the primary window manager for the GNOME Shell,[4] which is an integral part of GNOME 3. Mutter is extensible with plugins and supports numerous visual effects. GNOME Shell is written as a plugin to Mutter.

Adel Gadllah added support for HiDPI to version 3.13 of Mutter.[5]

In version 3.13.2 logind integration replaced mutter-launch.[6]

In version 3.13.3 (June 24, 2014) the server side bits of wl_touch_interface were implemented by Carlos Garnacho.[7][8][9][10]

Reception

OpenGL games run with a performance hit when using a compositing window manager; in June 2010, Phoronix evaluated this as similar for Mutter[11] and Compiz.[12] The default of Ubuntu 18.04 was reverted to Xorg citing issues with GNOME Shell and Mutter.[13] Muffin is a fork of Mutter by the Linux Mint team for their Cinnamon desktop environment. Cinnamon's shell, a fork of GNOME Shell, is written as a plugin for Muffin.
