## What it is
XLibre Xserver is a community-managed fork of the X.Org display server implementing the X11 protocol, with tear-free modesetting, atomic modesetting, and continued driver support. It runs on Linux, BSDs, macOS, and Windows and is built with Meson.

## Use cases
- run an X11 display server on Linux instead of Wayland
- replace X.Org server with an actively maintained fork
- use Xvfb or Xephyr for headless or nested X sessions
- support legacy Nvidia drivers on X11
- run X11 apps on macOS or Windows via XQuartz/Xwin
- isolate X clients with the Xnamespace extension

## When to choose
- you need an X11 display server with active maintenance and fixes
- you rely on X.Org features or drivers dropped elsewhere, including old Nvidia drivers
- you want tear-free rendering and atomic modesetting on X11
- you need X servers on multiple platforms including BSD, macOS, and Windows

## When to avoid
- you are starting a new project that can use Wayland natively
- you need a Wayland compositor or modern display-server features
- you prefer only officially distro-blessed X.Org packages

## Facets
- artifact type: application
