Mutter is a window manager initially designed and implemented for the X Window System, and recently has evolved to be a Wayland compositor. It became the default window manager in GNOME 3, replacing Metacity[5] which used GTK+ for rendering. Mutter uses a graphics library called Clutter giving it OpenGL capability. The name 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,[6] 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. Gala, a core component of the Pantheon desktop environment, is built using libmutter.[7][8] Budgie-wm, used in the Budgie desktop environment, is another window manager built on libmutter.[9][10]

Development

Adel Gadllah added support for HiDPI to version 3.13 of Mutter.[11]

In version 3.13.2 logind integration replaced mutter-launch.[12]

In version 3.13.3 (June 24, 2014) the server side bits of wl_touch_interface were implemented by Carlos Garnacho.[13][14][15][16]

Performance

OpenGL games run with a performance hit when using a compositing window manager; in June 2010, Phoronix evaluated this as similar for Mutter[17] and Compiz.[18]

Forks

Muffin

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.
