Simon Ser b094f8aeb3 scene/surface: don't cache frame pacing output
Storing the frame pacing output in a per-scene and per-surface
struct doesn't play well with multiple scenes. outputs_update is
only triggered for outputs the scene knows about, but operates on
all outputs the surface has entered regardless of the scene. Thus
leaving an output on one scene will not refresh the frame pacing
output on other scenes, and these other scenes will operate with
a stale frame pacing output. The surface will not receive any more
wl_surface.frame done events.

This also avoids keeping a dangling pointer around when the frame
pacing output is destroyed but the output isn't added in the scene.

wlroots

Pluggable, composable, unopinionated modules for building a Wayland compositor; or about 60,000 lines of code you were going to write anyway.

  • wlroots provides backends that abstract the underlying display and input hardware, including KMS/DRM, libinput, Wayland, X11, and headless backends, plus any custom backends you choose to write, which can all be created or destroyed at runtime and used in concert with each other.
  • wlroots provides unopinionated, mostly standalone implementations of many Wayland interfaces, both from wayland.xml and various protocol extensions. We also promote the standardization of portable extensions across many compositors.
  • wlroots provides several powerful, standalone, and optional tools that implement components common to many compositors, such as the arrangement of outputs in physical space.
  • wlroots provides an Xwayland abstraction that allows you to have excellent Xwayland support without worrying about writing your own X11 window manager on top of writing your compositor.
  • wlroots provides a renderer abstraction that simple compositors can use to avoid writing GL code directly, but which steps out of the way when your needs demand custom rendering code.

wlroots implements a huge variety of Wayland compositor features and implements them right, so you can focus on the features that make your compositor unique. By using wlroots, you get high performance, excellent hardware compatibility, broad support for many wayland interfaces, and comfortable development tools - or any subset of these features you like, because all of them work independently of one another and freely compose with anything you want to implement yourself.

Check out our wiki to get started with wlroots. Join our IRC channel: #wlroots on Libera Chat.

A variety of wrapper libraries are available for using it with your favorite programming language.

Building

Install dependencies:

  • meson
  • wayland
  • wayland-protocols
  • EGL and GLESv2 (optional, for the GLES2 renderer)
  • Vulkan loader, headers and glslang (optional, for the Vulkan renderer)
  • libdrm
  • GBM (optional, for the GBM allocator)
  • libinput (optional, for the libinput backend)
  • xkbcommon
  • udev (optional, for the session)
  • pixman
  • libseat (optional, for the session)
  • hwdata (optional, for the DRM backend)
  • libdisplay-info (optional, for the DRM backend)
  • libliftoff (optional, for the DRM backend)

If you choose to enable X11 support:

  • xwayland (build-time only, optional at runtime)
  • libxcb
  • libxcb-render-util
  • libxcb-wm
  • libxcb-errors (optional, for improved error reporting)

Run these commands:

meson setup build/
ninja -C build/

Install like so:

sudo ninja -C build/ install
