Mutter is a display server and window manager for the Wayland protocol ("compositor"). It is the default window manager for GNOME.

Mutter was initially a compositing window manager 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. The name "Mutter" is a combination of "Metacity" and "Clutter".

Window management

[edit]

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 since version 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]
  • Support for X11 was disabled at compile-time in GNOME 49 and officially dropped with the X11 session code removed GNOME 50, rendering Mutter exclusively a Wayland compositor. GNOME 49 and later can still run most X11 apps on the Wayland session via XWayland.

Forks

[edit]

Muffin

[edit]

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]
