The Xwayland manager now has 4 distinct phases: - Init and shutdown (Happening together with the compositor itself) - Start and stop In these last 2 phases, handle orderly initialization and shutdown of Xwayland. On initialization We will simply find out what is a proper display name, and set up the envvar and socket so that clients think there is a X server. Whenever we detect data on this socket, we enter the start phase that will launch Xwayland, and plunge the socket directly to it. In this phase we now also set up the MetaX11Display. The stop phase is pretty much the opposite, we will shutdown the MetaX11Display and all related data, terminate the Xwayland process, and restore the listening sockets. This phase happens on a timeout whenever the last known X11 MetaWindow is gone. If no new X clients come back in this timeout, the X server will be eventually terminated. The shutdown phase happens on compositor shutdown and is completely uninteresting. Some bits there moved into the stop phase as might happen over and over. This is all controlled by META_DISPLAY_POLICY_ON_DEMAND and the "autostart-xwayland" experimental setting. https://gitlab.gnome.org/GNOME/mutter/merge_requests/709 |

Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a scene graph and user interface toolkit.
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.

The coding style used is primarily the GNU flavor of the GNOME coding
style
with some minor additions such as preferring stdint.h types over GLib
fundamental types, and a soft 80 character line limit. However, in general,
look at the file you're editing for inspiration.
Commit messages should follow the GNOME commit message guidelines. We require an URL to either an issue or a merge request in each commit.
