One month ago we reported on YSERVER as a modern X11 server written in Rust with the help of Claude Code. Since then YSERVER has continued to advance in supporting more X11 functionality thanks to the help of Claude Code (AI) and out today is version 1.3 o this display server.

YSERVER developer Jos Dehaes wrote into Phoronix to share some of the recent features that landed in recent weeks, including FreeBSD support, Xinerama extension support, direct mode VT switching, display hotplug support, and more:

- FreeBSD support — tested on GhostBSD
- musl / Alpine builds working
- Display hotplug
- Direct-mode VT switching
- XINERAMA support
- XFIXES pointer barriers and XC-MISC XID recycling
- RANDR gamma correction (redshift works)
- Runtime XKB layout switching and keyboard LEDs driven from XKB state
- xauth support
- A lot of desktop/WM bug fixing

YSERVER has also been tested now with complete MATE, Xfce, and Cinnamon desktop sessions. Compiz has also been tested as has Openbox, Awesome, Enlightenment, FVWM3, WMaker, and others. On the hardware side testing has spanned from AMD and Intel to Snapdragon and Apple Silicon graphics.
