What’s New in Fedora KDE 40?

Image provide by the Fedora Team

Fedora Linux is a community developed and maintained operating system. Fedora KDE is one of our adaptations of Fedora Linux for your laptop or desktop. With this milestone release of Fedora KDE 40, we hope that you’ll be interested in trying an OS that belongs to you from start to finish, from install to first shut down, from UI customizations to major changes under the hood!

KDE Plasma 6

The all-encompassing change in Fedora KDE 40 is the introduction of KDE Plasma 6. It’s the first major release of the Plasma desktop environment in nine years! Additionally, Fedora KDE is one of the first major distros to ship Plasma 6, and we’re the first Fedora Linux desktop variant to ship Wayland-only (not to worry, we retain full support for X11 applications!), enabling the project to push forward improvements to Wayland for the benefit of the entire Linux community. This builds upon the work done in previous Fedora Linux releases to have Fedora KDE run in Wayland from login to shutdown by default.

Featured Highlights

  • There’s a new Overview Effect for keeping tabs on all of your open applications across all your virtual desktops.
  • Partial support for HDR is implemented in this release on the way to having full support.
  • Accessibility improvements have been introduced with color blindness correction filters.
  • A new look to the taskbar comes in the form of a floating panel! Plasma 6 also makes customizing panels easier than ever with an understandable UI to help users make the changes they want with minimal effort.
  • The Breeze UI theme that has been a hallmark of Plasma for a while gets a refresh with simplifications and modernizations where needed.
  • NeoChat, KDE’s Matrix client, is provided by default for you to try.
  • The Cube has returned! The new Overview Effect is cool, but using the Cube to manage your virtual desktops is a fantastic party trick to impress your friends next time you’re sharing your screen. 😉

You can find more changes and improvements in KDE Plasma 6 from their megarelease page!

A word about Kinoite…

If you have an interest in what all of the immutable / atomic / cloud-native / composable / image-based fuss is about, Fedora Atomic Desktops is a great entry point into that world. Case in point, check out Fedora Kinoite 40, an atomic implementation of Fedora KDE that also comes with Plasma 6!

  1. “The KDE Spin now includes KDE Plasma 6, and runs with Wayland out of the box.” – KDE spin has used Wayland out of the box since Fedora 34 🙂 In Fedora 40, it only offers the Wayland session out of the box, with no X11 session available unless the user installs it themself. (sudo dnf install kwin-x11 plasma-workspace-x11)

      I did it like this
      ee11@fedora:~$ dnf5 search plasma-workspace-x11
      Updating and loading repositories:
      Repositories loaded.
      Matched fields: name (exact)
      plasma-workspace-x11.src: Xorg support for Plasma
      plasma-workspace-x11.x86_64: Xorg support for Plasma
      ee11@fedora:~$ sudo dnf5 install plasma-workspace-x11.x86_64

      One question
      What is diferent kwin-x11 plasma-workspace-x11 between plasma-workspace-x11.x86_64

      I’m beginer

  2. I can’t seem to attract any attention for this Fedora 40 bug:
    It affects nouveau use with 2 monitors.
    I need somebody to update the bug record to point to Fedora 40 for me, please.

    We should notify the KDE community to add Fedora 40 to the top of this list: https://community.kde.org/Distributions

    I currently use barrier to share a mouse and keyboard between computers. Last time I checked, barrier couldn’t run under Wayland so I have stuck with X11. Can you explain, perhaps in another article, how X11-only applications such as barrier will be supported under the KDE spin of Fedora 40?

  5. Darvond

    Indeed, all in all a good release. I hope that when Plasma 6 levels off a bit, that they’ll send people over to the Oxygen Squared project. https://invent.kde.org/pinheiro/oxygen2

    Also eagerly awaiting Fedora to mainline LXQT 2.

    I’m setting aside some time this weekend to upgrade my main machine. 🤞

    Is DNF really the only way to upgrade KDE Spin? I don’t see any notifications about new release in Discover. I think it can be a deal-breaker for people who are not really advanced or just don’t follow new releases.

    • SlimDeluxe

      From 38 to 39 there was a notification to upgrade with Discover, but it took a couple of days to appear after 39 was released. I guess it will be the same for 40 🙂

    I had to manually download a new .iso for Fedora 40 KDE Plasma as under the Discover app usual method, it offered the upgrade but always failed at 61% download….not even beginning any upgrade (as far as I know, is there background overwrite happening in download process?)

    Also the DNF method metntioned above doesn’t make itself apparent, I can’t find it.

    I’m starting a fresh build from a fresh download of F40KP as I had only just freshly swapped nack to Fedora once I heard of this native inclusion of KDE Plasma s the default with Wayland end to end.

    What am I missing?

    It gives me synergy v1.14.6.19. But that refuses to work with Wayland, it wants X11.

    The blurb says “the first Fedora Linux desktop variant to ship Wayland-only (not to worry, we retain full support for X11 applications!)”.

    Does that mean I should be able to get the fc40 build of synergy to work ? If so, HOW ???
