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[5] which used GTK+ for rendering.

Window management[edit]

Mutter uses a graphics library called Clutter giving it OpenGL capability. Mutter is a portmanteau of 'M'etacity and Cl'utter'. 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.

Release history[edit]

Support for HiDPI was added to version 3.13 of Mutter by "Adel Gadllah".[7]

In version 3.13.2 logind integration replaced mutter-launch.[8]

In version 3.13.3 (June 24, 2014) the server side bits of wl_touch_interface were implemented by Carlos Garnacho.[9][10][11][12]


OpenGL games run with a performance hit when using a compositing window manager; in June 2010, Phoronix evaluated this as similar for Mutter[13] and Compiz.[14]


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.
