Canonical Ships Ubuntu 26.04 LTS 'Resolute Raccoon' Without Xorg Desktop Session

Ubuntu 26.04 LTS Marks a Historic Shift: Wayland-Only Desktop

Canonical has officially released Ubuntu 26.04 LTS, codenamed 'Resolute Raccoon' — the first long-term support release in the distribution's history to ship without an Xorg desktop session. The new version defaults exclusively to the Wayland display server, ending decades of reliance on the aging X Window System.

According to a Canonical spokesperson, the decision reflects a commitment to modern graphics architecture: 'Wayland offers superior security, smoother performance, and better support for modern hardware. Removing X.org simplifies the desktop experience and reduces maintenance overhead.'

New Kernel and Desktop Environment

Ubuntu 26.04 LTS runs on the Linux 7.0 kernel, which brings enhanced hardware support, improved scheduling, and better power management. The default desktop environment is GNOME 50, featuring a refined interface and new system monitoring capabilities.

The update also introduces two new default applications: a fresh video player and a redesigned system monitor. Canonical highlighted that these apps are built with GTK4 and leverage the latest GNOME technologies. The company also improved the App Center with native Deb package management features, allowing users to manage .deb files directly.

Long-Term Support and Security

Canonical promises at least 5 years of standard updates for Ubuntu 26.04 LTS. Users who subscribe to Ubuntu Pro receive an additional 5 years of security coverage, totaling up to 10 years of support. This extended lifecycle is designed for enterprise and server deployments.

Jack Mitchell, a Linux system analyst at a major cloud provider, commented: 'The 10-year security window with Ubuntu Pro is a game-changer for organizations that need to comply with strict auditing requirements. The Wayland-only move will take some adaptation but is the right long-term direction.'

Background

Ubuntu has traditionally offered both X.org and Wayland sessions since version 17.10. Over successive releases, Wayland gradually improved in stability and compatibility. Canonical first hinted at dropping X.org when GNOME 40 introduced native Wayland support. The transition accelerated with Ubuntu 22.04 LTS, which made Wayland the default for most users but still kept X.org as a fallback.

Ubuntu 24.04 LTS continued this dual-session approach. Now, with 26.04 LTS, X.org is completely absent from the default installation. Users who require legacy X11 applications can still install the X.org packages manually, but no official session is provided.

What This Means

The removal of X.org from the default desktop marks a pivotal moment in Linux desktop history. Applications that depend on X11-specific features — such as screen recording tools, remote desktop software, and some proprietary apps — may encounter compatibility issues. However, the Wayland ecosystem has matured significantly, with most major applications now supporting it natively.

For everyday users, the transition should be seamless. GNOME 50's new system monitor and video player provide a polished experience out of the box. The Linux 7.0 kernel offers better performance on cutting-edge hardware, including Intel Meteor Lake and AMD Ryzen 8000 series processors.

Canonical expects existing Ubuntu 24.04 LTS users to upgrade gradually. The company has published detailed upgrade guides covering package compatibility and configuration migration. For more information, see the full features overview or the upgrade guide from 24.04 LTS.

What’s Changed Since Ubuntu 25.10?

Compared to the non-LTS Ubuntu 25.10 release, 26.04 LTS adds the Wayland-only session, Linux 7.0 kernel, and GNOME 50. The new system monitor and video player replace older GNOME apps. Deb package management in App Center is also new.

Upgrading from Ubuntu 24.04 LTS

Users on 24.04 LTS should note that the leap to 26.04 LTS involves a major kernel and desktop transition. Canonical recommends testing critical applications in a virtual machine before upgrading production systems.
