Ubuntu desktop
Initially, Ubuntu 21.04 includes Linux kernel 5.11, which has some interesting software features and support for newer hardware. AMD implemented better support for Vangogh, Green Sardine and Dimgrey Cavefish APUs of, and the Intel DG1 graphics card for desktop works now without additional drivers or patches. The performance with BTRFS and NFS file systems has been improved, while there is also support for Intel SGX, a feature on some Intel processors that provides secure zones for application data.

This release also marks the long-awaited going to Wayland, replacing the X desktop server that has been a key component of most Linux environments for decades. The Wayland usually has faster performance and smoother graphic effects than the X., and better compatibility with advanced display functions, such as fractional scaling. In addition, Canonical stated in its official announcement that Firefox, OBS Studio and many applications built with Electron and Flutter, take advantage of Wayland automatically, for smoother graphics and better fractional scale.

Some other distributions - As the Fedora - have been using Wayland for quite some time, but Ubuntu hesitated to change - although it tried in 2017. If you use NVIDIA graphics card, the operating system will still be default to X11.

Ubuntu 21.04 also has an update, the Yaru, which changes certain elements of the desktop to one dark theme (dark theme) while keeping the rest of the operating system bright. Ubuntu has had its choice of light and dark themes for over a decade, but now the default look is a combination of both styles.

However, Ubuntu 21.04 does not have the latest GNOME 40 desktop environment, which has a redesigned screen, configuration improvements and updated default applications. Ubuntu adds some additional extensions on the vanilla GNOME desktop, so Canonical probably needs more time to update them before it can be "moved" to GNOME 40. This also means that is missing, at least for the time being, and GTK 4.0.
