KaOS - 2024.09
It is a great pleasure to present to you the September release of a new stable ISO.
For the Plasma desktop, the latest KDE Gear (24.08.1), Plasma (6.1.5), and Frameworks (6.6.0) are included. All built on Qt 6.7.2. Among the many changes included in KDE Gear 24.08:
- New features in Dolphin are designed to make it easier to access and manage files and folders that require administrative privileges
- Konsole: if you need to bookmark something important in a long output, double-click the scroll bar to set a position marker. You can then quickly scroll back and locate it later.
- Kdenlive: brand new keyframe curve editor to customize effects, and easing methods (Cubic in/out and Exponential in/out) for fades.
More application are now ready to use Qt6 and Frameworks 6, the big one now being Calligra. Since Calligra is again actively maintained and developed, it has returned to being the default office suite for KaOS. Another one that is now Qt6-based is Virtualbox.
The UI of the installer has been updated for quite a few pages. this includes an option to choose either Calligra or LibreOffice as the preferred office suite. You will also see that the bootloader selection page and sound backend page are more integrated with Plasma 6 (through kirigami).
There also is now an option in the installer to install with the all-new filesystem bcachefs, it is still in experimental stage, but is included in the kernel build, and the needed bcachefs-tools are available in the repositories. Calamares can use bcachefs when used in manual mode, though no specific settings for this filesystem have been implemented yet.
Among the new packages included is Zed, a Rust-based code editor, a very fast and capable alternative to vscode. KaOS is also starting to actively follow the development of a complete independent browser Ladybird. This browser is in pre-alpha state, can be used for simple browsing and will see a monthly build in the repositories.
Updates to the base of the system included a move to Boost 1.85.0/ICU 75.1 stack, Ruby 3.3.5, Perl 5.38, kernel moved to Linux 6.10.11, Systemd 253.25, ZFS 2.2.6, KMod 33, OpenSSL 3.3, FFMPEG 6.1, OpenJDK 17 and Mesa 24.2.3. A new Phonon sound backend is in use. So far VLC was used, but there is no Qt6 porting for VLC yet. Using phonon-mpv as default now, gives a fully Qt 6 ready backend.
New for this ISO is to no longer include the kernel modesetting for all graphics cards, thus shaving roughly 700 Mb of the ISO size.
Four years after being end of life, GTK2 is finally removed from the KaOS repositories. The one major application left that still required GTK2 was Ardour, but with 8.4.0, an internal YTK is used, thus GTK2 is now gone.

SDDM 0.20.0 added the option to run this display manager in Wayland mode, so KaOS is one step closer to being ready to move away from X11. The shell used to run in Wayland mode is kwin_wayland (upstream default is using Weston).
The automated partitioning option in the installer (Calamares) now offers the use of all popular filesystems, so no need to use manual partitioning to be able to choose XFS, EXT4, BTRFS, or ZFS.
Big thanks goes to YourHostingSolutions for not only providing a mirror but also providing a server for KaOS. With the discontinuation of Fosshost, a new server was sorely needed.
After almost two years of testing IWD, it is now in such a good state that it has replaced Wpa_Suplicant as the default wireless daemon for KaOS. Similar, Pipewire has replaced PulseAudio as the default sound/low-level multimedia framework.
A shift has started as to how all Python packages are build. Historically, just about all were build with setuptools though a setup.py script. PEP17 is the new standard for building python packages, see https://peps.python.org/pep-0517/. At this stage, KaOS is testing this transition with different new Python build tools, such as Python-flit & Python-build, with Python-wheel currently in use to install the build packages.
For Nvidia, longterm supported versions 390xx and 470xx are include, alongside the latest released version.
Since LibreOffice 6.2, it is now possible to supply this as a pure Qt6/kf6 application. LibreOffice has thus replaced Calligra as the default Office Application for KaOS.
KaOS’ creation Croeso (Welsh for welcome) for helping with configuring a new install is included. It will run on the newly installed system and offers to adjust some 15 commonly used settings, includes a custom Wallpaper selector, distribution info, and the option to select packages to install from six different groups. It is written in QML and fits well with the Welcome application used in the Live system. The latter includes an Installation Guide.
There is an option to verify the authenticity of downloaded KaOS ISO files through GPG signature verification, see the Download page for further details and instructions.
The artwork includes custom icon themes for light and dark themes. Midna and Midna Dark both create a complete unified look from boot-up all the way through logout.
This ISO uses the CRC and finobt enabled XFS filesystem as default. CRCs enable enhanced error detection due to hardware issues, whilst the format changes also improves crash recovery algorithms and the ability of various tools to validate and repair metadata corruptions when they are found. The free inode btree does not index used inodes, allowing faster, more consistent inode allocation performance as filesystems age.
For UEFI installs, KaOS uses the simple, transparent but quite powerful systemd-boot as bootloader.
Octopi is becoming a very crucial part of full system maintenance for KaOS. It is not just a GUI frontend to pacman. Tools like making sure a mirror is synced before starting any update, looking at the pacman logs, an option to get a paste from a complete snapshot of all info of a system with the SysInfo tool are included. Also included are very simple ways to open files, like copy to clipboard the file path shown in Octopi. To make sure the system doesn’t start using too much disk space for the pacman cache, but still giving the user the option to retain some recent packages, the cache-cleaner tool is a great addition. The built-in tool to access KCP has now a much clearer place with the addition of its own “foreign” icon in the menu-bar. When viewing package info it is now possible to click the depends of such a package. New added is the option to select custom icons for the systemtray.

To avoid any misunderstanding and confusion, KaOS is not based upon, derived of, or inspired by any one particular distribution. It is completely independent, build entirely from scratch with its own repositories. To read more about this see Based. A rolling release distribution never has a final
release, every ISO is merely a snapshot of the current status of the repositories. An idea what is currently available:
The ISO ships with Frameworks 6.4.0, Plasma 6.1.3, KDE Applications 24.05.2, Linux 6.9.9, Systemd 253.22, Kmod 32, NetworkManager 1.46.4, LibreOffice 24.2.5, Elisa, Xorg-Server 1.21.13, Mesa 24.1.4, Glibc 2.39, GCC 13.2.1, non-free Nvidia 555 and Python3 3.11.9 to name a few.
The package manager is Pacman 6.0.2, with the simple but powerful Octopi 0.16.2 as GUI frontend. Falkon is the default, Qt based, web browser. GFXboot is included with KaOS artwork, Grub theme is Midna, Look & Feel is a KaOS exclusive version Midna.
Repositories of KaOS will stay limited in size and expect it to stay at the current maximum of about 2100-2200 packages. A gist of what is available, besides the stable kernel there is Linux-next 6.11, VLC, Vokoscreen, Blender, Kodi, Calibre, Sigil, Vulkan packages, a few games like 0ad and Knights. A limited number of the most well-known GTK applications are available, for example, Firefox 130, Chrome 131, Ardour 8.7.0, Inkscape 1.3, GIMP 2.99.18 and Thunderbird 128. Complete language packs are available for KDE, Calligra, Firefox, LibreOffice and Thunderbird. For IM, Fcitx 4.2.9.9 is available as a rather complete group.
Known issues:
- Installing on RAID is currently not possible
To create reliable installation media, please follow the instructions from the Download page. KaOS’s ISO’s do not support Unetbootin or Rufus, and DVDs need a burn speed no higher than 4x.
