Help develop KDE Linux

The KDE Linux team always appreciates help developing KDE Linux into the operating system of the future!

• To talk with the KDE Linux developers, use Matrix.
• To propose changes, submit a Merge Request in one of the relevant git repositories.
• To report issues in the KDE Linux operating system itself (i.e. OS design, integration, system services, etc), use invent.kde.org, and ignore the scary red banner at the top of the page.
• To report issues in KDE Plasma or any KDE apps, use bugs.kde.org.
• To get help with something related to KDE Linux, use discuss.kde.org, and tag your post with “kde-linux”.

CI Images

The OS images produced by CI runs can be downloaded from here. This can be useful to test changes from a merge request locally.

Improve Local Build Speed

In order to speed up local builds, create a mkosi.local.conf file in the root of the repository with the following content:

[Content]
Environment=LOCALE_GEN="en_US.UTF-8 UTF-8" # replace with your locale`
Environment=MIRRORS_COUNTRY=us # replace with your country code`
Environment=PARALLEL_DOWNLOADS=50 # if your internet connection is fast

You need to be using the Btrfs storage driver for docker, otherwise this won’t really work.

If your host filesystem uses Btrfs (like KDE Linux), add the following to /etc/docker/daemon.json

{
  "storage-driver": "btrfs"
}

Official docker documentation explaining this can be found here.

If you don’t use Btrfs for your host machine, you can still create a Btrfs volume backed by a file like so:

systemctl stop docker.socket docker.service || true
fallocate -l 64G /store/docker.btrfs
mkfs.btrfs /store/docker.btrfs
[ -d /var/lib/docker ] || mkdir /var/lib/docker
mount /store/docker.btrfs /var/lib/docker
systemctl restart docker.socket docker.service

Then run:

./build_docker.sh --incremental
