XLibre Xserver is a community-managed display server for the X Window System Protocol Version 11.
It incorporates unreleased features from X.Org while adding its own enhancements, including TearFree modesetting by default and optional atomic modesetting support. The tool supports multiple Nvidia driver versions and introduces the Xnamespace extension for separating X clients. It also offers flexibility in seat management by supporting both seatd and systemd-logind, and includes Xfbdev, a generic framebuffer Xserver for Linux.
Developers should choose this tool if they need an X11 server with active maintenance and community-driven development. It suits projects running on Linux, BSD variants, macOS, and Windows that require X11 functionality with modern modesetting capabilities and broader driver support than the original X.Org Server. The project explicitly positions itself as building on X.Org's foundation while adding community improvements and fixes based on merit.
The project maintains continuous integration builds across multiple operating systems including several BSD variants, Linux, macOS, and Windows. Development activity centers on active community participation, with regular cleanups, bug fixes, and feature additions. The tool is available through distribution packages in multiple systems, with source building supported via the Meson build system.
