Simon Ser 1100f3a40b backend/drm: don't clear pending cursor FB on failed commit 
The previous fix tried to side-step cursor->pending_fb completely.
However that messes up our buffer locking mechanism.

Instead, stop clearing the pending cursor FB on a failed commit. The
pending cursor FB will remain for the next commit.

Fixes: 6c3d080e25 ("backend/drm: populate cursor plane's current_fb")
(cherry picked from commit 4dee7a2f6f)

wlroots

Pluggable, composable, unopinionated modules for building a Wayland compositor; or about 50,000 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: #sway-devel on Libera Chat.

wlroots is developed under the direction of the sway project. A variety of wrapper libraries are available for using it with your favorite programming language.

Building

Install dependencies:

  • meson
  • wayland
  • wayland-protocols
  • EGL
  • GLESv2
  • libdrm
  • GBM
  • libinput
  • xkbcommon
  • udev
  • pixman
  • libseat

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 build/
ninja -C build/

Install like so:

sudo ninja -C build/ install
