Mutter (software)

GNOME window manager and display server From Wikipedia, the free encyclopedia

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. "Mutter" is a combination of "Metacity" and "Clutter".

Window management

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 plug-ins, and supports numerous visual effects. GNOME Shell is written as a plug-in to Mutter.
