If you’re a developer and use KDE, you’re going to be interested in a new feature KDE is working on for KDE Linux.

In my last post, I laid out the vision for Kapsule—a container-based extensibility layer for KDE Linux built on top of Incus. The pitch was simple: give users real, persistent development environments without compromising the immutable base system. At the time, it was a functional proof of concept living in my personal namespace.

Well, things have moved fast.

Not only is Kapsule now available in KDE Linux, it’s also properly integrated with Konsole now. This means you can launch Kapsule containers right from the new tab menu in Konsole for even easier access. They’re also working on allowing users to easily launch graphical applications from the containers and have them appear in the host desktop environment, and they intend to make the level of integration with the host more configurable so developers can better tailor their containers to their needs.

KDE’s Nate Graham has published a status update about KDE Linux, the KDE project’s new immutable Linux distribution, intended to be the “KDE OS” showcasing the best of the KDE community. While the project is approaching the beta stage, it’s currently still in alpha, but from what I gather from friends who are using it, the alpha label might actually be like how Haiku is supposedly still alpha: intended more to scare people away for now than ana ctual descriptor of the state of the software.

Recently, KDE Linux enabled delta updates, possibly dramatically reducing the size of updates. Before delta updates were enabled, a system update would come in at 7GB, while with delta updates enabled, it’s gone down to 1-2GB. In addition, plasma-setup and plasma-login-manager have been added to KDE Linux, which are, respectively, a first-run setup assistant and KDE’s new login manager. This new login manager was forked from SDDM, and specifically targets Wayland, and comes with much deeper Plasma integration than SDDM. Note that SDDM will remain available for platforms that don’t use Wayland.

KDE Linux has also massively improved its hardware support, and the list is long; from scanners to fancy multi-button mice, from Android devices to professional audio devices, and much more. Performance has been improved as well, the boot manager menu will no longer be shown at every boot but only when needed, the wireless regulatory domain is now properly set and managed, and much, much more.

I’m keeping an eye on KDE Linux as a possible replacement for my Fedora KDE installations if Fedora ever loses the plot, even if it’s an immutable distribution relying on Flatpak. I’m a KDE user, and I want the latest and greatest the KDE community has to offer without going through an distributor.

KDE developer Herz published a detailed look at the immense amount of work they’ve done cleaning up the developer onboarding documentation for KDE.

All that just to say that I’m finally content with the state of beginner onboarding docs in our KDE Developer Platform. That is to say, all the beginner docs fixes I wanted to add to Develop are either already there or have merge requests ready or almost ready.

Judging by the article, KDE’s developer documentation really were in need of major work, and it’s great to see that thankless task being done. One of the areas where KDE lags behind GNOME is that the latter has a more vibrant application ecosystem, with tons of great GNOME applications under active development. Now, I’m not saying it’s the state of KDE’s documentation is the sole reason for this, but I’m sure it wasn’t helping either.

Improving documentation is not a particularly glamorous task, but it’s vitally important nonetheless.

The KDE project has made the call.

Well folks, it’s the beginning of a new era: after nearly three decades of KDE desktop environments running on X11, the future KDE Plasma 6.8 release will be Wayland-exclusive! Support for X11 applications will be fully entrusted to Xwayland, and the Plasma X11 session will no longer be included.

They’re following in the footsteps of the GNOME project, who will also be leaving the legacy windowing system behind. What this means in practice is that official KDE X11 support will cease once KDE Plasma 6.7 is no longer supported, which should be somewhere early 2027. Do note that the KDE developers intend to release a few extra bugfix releases in the 6.7 release cycle to stabilise the X11 session as much as possible for those people who are going to stick with KDE Plasma 6.7 to keep X11 around.

For people who wish to keep using X11 after that point, the KDE project advises them to switch to LTS distributions like Alma Linux, which intend to keep supporting Plasma X11 until 2032. Xwayland will handle virtually all X11 applications running inside the Wayland session, including X11 forwarding, with similar functionality implemented in Wayland through Waypipe. Also note that this only applies to Plasma as a whole; KDE applications will continue to support X11 when run in other desktop environments or on other platforms.

As for platforms other than Linux – FreeBSD already has relatively robust Wayland support, so if you intend to run KDE on FreeBSD in the near future, you’ll have to move over to Wayland there, as well. The other BSD variants are also dabbling with Wayland support, so it won’t be long before they, too, will be able to run the KDE Plasma Wayland session without any issues.

What this means is that the two desktop environments that probably make up like 95% of the desktop Linux user base will now be focusing exclusively on Wayland, which is great news. X11 is a legacy platform and aside from retrocomputing and artisanal, boutique setups, you simply shouldn’t be using it anymore. Less popular desktop environments like Xfce, Cinnamon, Budgie, and LXQt are also adding Wayland support, so it won’t be much longer before virtually no new desktop Linux installations will be using X11.

One X down, one more to go.

As part of the KDE Plasma 6.5 release, we also got a new release of Plasma Mobile. As there’s a lot of changes, improvements, and new features in Plasma Mobile 6.5, the Plasma Mobile Team published a blog post to highlight them all. The biggest improvement is probably the further integration of Waydroid, a necessary evil to run Android applications until the Plasma Mobile ecosystem manages to become a bit more well-rounded. Waydroid can now be managed straight from the settings application and the quick settings dropdown.

Furthermore, the lockscreen has been improved considerably, there’s been a ton of polish for the home screen and the user interface in general, the quick settings panel can now be customised to make it fit better on different form factors, the first early test version of the new Plasma mobile keyboard is included, and so much more. This is definitely a release I would want to try out, but since I don’t have any of the supported devices, I’m a bit stuck.

This is, of course, one of the two major problems facing proper mobile Linux: the lack of device support. It’s improving due to the tireless work of countless volunteers, but they’re always going to be swimming upstream. The other major problem is, of course, application availability, but at least Waydroid can bridge the gap for the adventurous among us.
