# Kubuntu 26.10 ships Plasma 6.7, drops default X11 support

> **Key takeaway:** Kubuntu 26.10 is the first release to ship Plasma 6.7 by default and the last to offer the X11 session package, with Wayland now the sole supported display protocol.

## Summary
Kubuntu 26.10 "Stonking Stingray" is now available as an interim release based on Ubuntu 26.10, shipping Plasma 6.7.5, Qt 6.11.2, KDE Frameworks 6.29.0 and Linux kernel 7.3. It will receive updates for 9 months until July 2027. The release marks a significant transition: Wayland is the default and only supported session, while X11 is not installed by default and the plasma-session-x11 package will be removed after this release.

## What's new in Kubuntu 26.10
- **Plasma 6.7.5** with per-screen virtual desktops, faster Overview switching (Meta+W), and Discover UI improvements
- **Union theming system** included as tech preview (kde-style-union)
- **Wayland default**, X11 session not installed; plasma-session-x11 package to be removed in future releases
- **Kernel 7.3.0-9.9**, systemd 261.3, 100% Rust coreutils (uutils replaces remaining GNU cp/mv/rm)
- **Developer toolchain**: GCC 15.2, Python 3.14.7, Rust 1.97, Go 1.27, LLVM 22, OpenJDK 25
- **TPM-backed full-disk encryption** now installable without hardware root of trust when combined with PIN/passphrase
- **Upgrade blocker**: TPM-encrypted 26.04 LTS systems cannot upgrade at release; expected later in 26.10 lifecycle

## Why it matters
The removal of default X11 support in a mainstream Ubuntu flavor signals accelerating Wayland adoption across the KDE ecosystem, while the complete Rust coreutils migration and TPM encryption improvements reflect broader trends in Linux distribution security architecture.
