/usr/bin/gnome-shell goa-daemon gvfsd The Shell acts as a compositing manager for the desktop, and displays both application windows and other objects in a Clutter scene graph. Much of the code of the shell is written in Javascript but uses Clutter and GNOME platform libraries via GObject Introspection and JavaScript bindings for GNOME. For window management and compositing, the shell builds off of a Metacity branch called Mutter, which adds Clutter-based compositing to Metacity.
