Open-source developer Jos Dehaes wrote in to Phoronix today in announcing a new X11 server he has been working on from scratch that has been quietly developed to this point but now ready to announce to the world... The YSERVER.

The yserver is a "modern X11 server written from scratch in Rust." In looking at the latest Git activity, it's also written with the help of Claude Code AI.

The stated goal is to not be a 1:1 replacement to the X.Org Server but focusing on modern functionality for X11 clients and foregoing the legacy bits:

"The goal is not to clone Xorg. It is to provide a practical X11 server that runs real desktop environments, window managers, and applications on modern Linux while dropping legacy baggage (multiple screens, non-TrueColor visuals, indirect GLX, the DDX driver ABI, endian-swapped clients, and so on)."

The yserver can currently run a full MATE, Xfce, or Cinnamon X11 desktop. The prominent X11 extensions from RandR to DRI3, GLX, MIT-SHM, Composite, and others are supported. And, yes, with working Compiz goodness too:

This Rust-based X11 server is open-source under an MIT license. Those wishing to learn more about the YSERVER can do so via the GitHub repository.
