The first release candidate for X.Org Server 26.1.0, version 26.0.99.901, has been launched, featuring a significant architectural overhaul that separates Xwayland into its own project and eliminates the autoconf build system. This update has resulted in the removal of over 21,000 lines of legacy code, including outdated display driver extensions, and has tightened security defaults by disabling byte-swapped clients and font server connections by default. The new version requires the meson build system and introduces several enhancements, such as DPMS 1.2 support and multi-CRTC capabilities for virtual framebuffers. Additionally, the emergence of the XLibre community fork highlights the evolving landscape of the X Window System, as it caters to users seeking older Nvidia driver support and a more community-driven approach
