This protocol allows for explicit synchronization of GPU operations by Wayland clients and the compositor. Xwayland can make use of this to ensure any rendering it initiates has completed before the target image is accessed by the compositor, without having to rely on kernel-level implicit synchronization. Furthermore, for X11 clients that also support explicit synchronization using the mechanisms exposed in the DRI3 and Present extensions, this Wayland protocol allows us to simply forward the timeline, acquire, and release points directly to the compositor, ideally avoiding any premature stalls in the presentation pipeline.

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
