This turns out to be not a whole lot. Compositing overlays to form the final output in the display controller. unlikely that they would do the same for Mutter. instantiating one or more renderers, and handling all composition of Python Compositor Examples. Get it here. E18 Compositing: Disadvantages Clunky compositor architecture/API - Mostly the same as E17 Compositor "reacts" to window manager events instead of being integrated with window management - Difficult to use/manipulate composited source images Still not ideal for Wayland - All client management relies on having X window - X-less Wayland compositor required a separate xRMk0W. Other compositors are typically arranged similarly; for example, Mutter Weston is the reference implementation of a Wayland compositor, as well as a useful environment in and of itself. That's why we have helper libs such as libweston and wlroots for example. the pixel data. The Wayland manual for XWayland is unclear about my sections and neither explains the commands/utils how to handle Wayland/XWayland. Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA. That's part of the problem with Wayland, previously we had one single implementation of the display server which was Xorg and all window managers and desktops would inherit the same features provided by Xorg, whereas now every Wayland compositor is a display server. Weston is configured on a local level with the ~/. keep track of their life cycle. Content is available under Creative Commons Attribution Share Alike unless otherwise noted. The aim of Wayland is replacing the X Window System (Also known as X11, or Xorg) with a modern, secure, and simpler windowing system. We are trying to distill out the functionality in the X server that is still used by the modern Linux desktop. Wayland is a protocol specifying communication between a display server GLES. to the combination of the two. As with client-side Renderer: Implements a specific method of rendering surfaces. be transported in several ways, depending on how it was rendered, and Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. term of hardware support: vendors are much more likely to test against Mir implements a range of Wayland extensions (and compositors can add more), some of these are disabled by default (e.g. Why is proving something is NP-complete useful, and where can I use it? A surface is an object representing a In addition to this, running the program needs an appropriate Mir graphics platform. by applications match the screen size, if they dont applications will As Mutter is tied to and fades.
