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,[2] which uses GTK+ for rendering, while Mutter uses a graphics library called Clutter, and through it also supports OpenGL. The name is a portmanteau of Metacity Clutter.

Mutter can function as standalone window manager application for GNOME-like desktops, and serves as the primary window manager for the GNOME Shell desktop,[3] 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.[4][5] budgie-wm, the window manager used in the Budgie desktop environment, is another window manager built on libmutter.[6][7]

Development

Adel Gadllah added support for HiDPI to version 3.13 of Mutter.[8]

In version 3.13.2 logind integration replaced mutter-launch.[9]

In version 3.13.3 (June 24, 2014) the server side bits of wl_touch_interface were implemented by Carlos Garnacho.[10][11][12][13]

Performance

OpenGL games run with a performance hit when using a compositing window manager; in June 2010, Phoronix evaluated this as similar for Mutter[14] and Compiz.[15]

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.
