Quotes From the Announcement E-Mail by the Founder

Since today is our 1st anniversary, we're releasing the XLibre Xserver version 25.1.6, and as almost half a year has passed, we declare our 25.1 series stable. :)

Many thanks to all the contributors, whether writing code, testing, PR work, distro packaging, etc., etc. Without you, this project won't be possible.

Let's celebrate 1 year of hard and prosperous work! :)

Availability of XLibre

Eleven (11) distributions have already switched to XLibre as the default X11 server implementation like, Artix Linux, GhostBSD, OpenMandriva, and Vendefoul Wolf. There are community-maintained third-party packages for XLibre available for over 35 distributions and their spins, including Arch Linux, Debian, DragonFly BSD, Fedora, FreeBSD, Gentoo Linux, GNU Guix, Linux Mint, MX Linux, RHEL, Slackware, Ubuntu, and Void Linux.

The project's wiki page „Are We XLibre Yet?“ 10 lists them all.

About XLibre

XLibre is the most actively developed community-maintained X11 display server. It has been forked from the X.Org Server on June 5, 2025, and is led by a core team of more than ten (10) members, including its founder, Enrico Weigelt, a.k.a. metux. It's striving to improve the existing code base while maintaining backward compatibility to make X11 a viable choice for the future.

On its first release on June 21, 2025, the XLibre team set free several features and bug fixes that had been living in the X.Org Server master branch for up to four years. In the course of its first year, the now more than fifty (50) unique contributors did numerous code cleanups, fixed bugs, and implemented features, such as the ones mentioned above in more than 3,600 commits to the master branch alone. The 25.0 series of the Xserver saw 24 patch releases and the 25.1 series six (6). There were 30 releases in total.

The independent project is driven by its international community and striving. There‘ll be another feature release later this month, more prototyping on the HDR implementation as well as new features like the runtime configuration of the Xnamespace extension.

Congratulations to the XLibre team on your first anniversary and the stable 25.1 release!

As one of the OpenMandriva maintainers (I also had my hands in xlibre packaging), we are proud to be among the distributions adopting XLibre by default. Thank you for all the hard work, cleanups, and critical security fixes. Looking forward to the future updates and our continued collaboration!

[callmetango]

Thank you very much, and thank you as well for OpenMandriva being one of the first distributions to support and package XLibre! Much appreciated, and we're looking forward to our continued collaboration too.

I'd like to join the congratulations. For over a decade, FreeDesktop / RedHat developers have been telling us in conference presentations, blog posts and numerous interviews that much of what was done in this XLibre release was simply impossible due to the Xorg architecture. But it turns out all that was actually needed, was a year of work and one brave hacker who dared to say "no" to the corporate machine. You're restoring my faith in hacker culture.
