KDE neon now on Linux 5.8

Here at KDE neon we pride ourselves on giving you the latest from KDE built pronto and QAed and shipped to you with no questions asked. We also base on the stable Ubuntu LTS 20.04 release giving a generally stable system. If you want an updated version of an app which isn’t from KDE we advise you to use a non-distro package from the Snap store, AppImage or Flatpak. But Linux has one property which is still inconvenient for the end user even the more nerdy of end users, which is that drivers are shipped with the Linux version you get and there’s no stable programmer interface for them so they can’t easily be shipped externally. That means if you use Linux 5.4 which is what comes with KDE neon and Ubuntu 20.04 you will get drivers which are a few years old, which is no good for those shiny new AMD Radeon graphics chips. So we’ve now switched the installable images to the HWE build which brings in Linux 5.8. Neon installs should just install it on upgrade and use it on the next boot. Chat on our forum and report bugs on bugs.kde.org as ever.

KDE neon 5.22 is Here

Plasma 5.22 was released yesterday and so the hard working continuous automation and continuous deployment guinea pigs at KDE neon compiled it all and bumped the version number and spun new installable ISOs and Docker images for you to try it. Existing users can just upgrade as normal.

Download the ISO from https://neon.kde.org/download and boot it up
Or try the docker image. Xephyr :2 -screen 1024x768 & docker run -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=:2 --security-opt seccomp=unconfined kdeneon/plasma:user startplasma-x11

KDE neon’s Qt is Now Built from KDE’s Git Branches

Recently KDE started to maintain a collection of patches for Qt 5. This is because Qt 5 came to end of life with Qt 6 now released (KDE Frameworks has started the slow process of moving to Qt 6). With many Qt 5 users out there the Qt Company are selling a maintained verson of Qt 5 but for the community KDE has started a collection of patches to fix the bugs. In KDE neon we like to build everything in KDE directly from KDE so we have now moved to building Qt too. This means our Qt now calls itself 5.15.3. We also updated PyQt to 5.14. Let us know if you find any problems.

KDE neon Unstable Qt 6 Package Available

Today at KDE neon tower we are feeling cute. And sixy. We have an early-prototype-preview-no-stability-guaranteed Qt 6 package.

This is in the KDE neon Unstable edition so if you run that you can just

sudo apt install qt6
/usr/examples/widgets/widgets/digitalclock/digitalclock

And you’ll have a digital clock.

Or if you run any other distro you can use the Docker image, which would be something like:

docker run -v `pwd`:/workspace -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=:0 --security-opt seccomp=unconfined -ti kdeneon/plasma:unstable bash
neon@68c3ba3fc955:~$ sudo apt update
...
neon@68c3ba3fc955:~$ sudo apt install qt6
...
export QT_PLUGIN_PATH=/usr/plugins
/usr/examples/widgets/widgets/digitalclock/digitalclock

It’s installed into /usr and Qt isn’t too smart about where it goes under that so the paths don’t follow FHS or Debian policy yet, that might change.

KDE neon 5.20

Our beautiful desktop Plasma 5.20 has been released and with it the version bump in KDE neon User Edition to 5.20.

KDE neon 5.20 installed running KDE neon 5.20 on Virtualbox and KDE neon 5.20 Docker image

To get it you can

Bad Snapshot Today

A bad snapshot in KDE neon user edition today caused an incomplete build to get into user editions. If you are affected downgrade with


sudo apt-get install libkwaylandserver5=5.19.5-0xneon+20.04+focal+build10

Sorry about that, we’ll add additional QA checks to prevent similar issues from happening again.

KDE neon Rebased on 20.04

KDE neon is our installable Linux with continuous integration and deployment. It’s based on Ubuntu who had a new Long Term Support Release recently so we’ve rebased it on Ubuntu 20.04 now.

You should see a popup on your install in the next day or so. It’ll ask you to make sure your system is up to date then it’ll upgrade the base to 20.04 which takes a while to download and then another while to install.

Afterwards it should look just the same because it’s the same wonderful Plasma desktop.

Upgrade Instructions

The installable ISOs are also updated and this time they all use the Calamares installer.

Testing and Unstable edition, these are built from the soon-to-be-released Git branches and the untested Git branches. Alas trying the installable ISOs today we found some bugs in the Git Calamares installer so they’re not published yet but the upgrader will still popup on existing installs. Update these are up now

We implemented OEM install mode in Calamares so the other way to get neon is to buy a KDE Slimbook III and it’ll use that.

We also implemented a full disk encryption tickbox in Calamares.

The Docker images are still to be updated and the Snap packages also need moved over.

Going Focal

Here at KDE neon base camp we have been working on moving the base of our system to Focal, Ubuntu 20.04. If you’re interested in the mechanics you can see the status, and indeed help out, on our 20.04 workboard.

But probably you’re more interested in giving it a try. This is in testing mode still and comes with a no money back warranty. Instrucitons are on the testing forum thread. You can either do an upgrade or a full install from the preview ISOs. Let us know how you get on!
