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[4] which used GTK for rendering.

Window management[edit]

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,[5] which is an integral part of GNOME 3. Mutter is extensible with plug-ins, and supports numerous visual effects. GNOME Shell is written as a plug-in to Mutter.

Release history[edit]

Support for HiDPI was added to version 3.13 of Mutter by Adel Gadllah.[6]

In version 3.13.2 logind integration replaced mutter-launch.[7]

In version 3.13.3 (June 24, 2014) the server side bits of wl_touch_interface were implemented by Carlos Garnacho.[8][9][10][11]



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.[12]
