KaOS - 2016.09

It is with great pleasure to present to you KaOS 2016.09. With this ISO KaOS has gone back to a fully integrated build of the different KDE parts. Instead of building Frameworks, Plasma and KDE Applications on their own separate release schedules all are now build the same day of any Frameworks release. To accomplish this Plasma 5 is now build from the latest commits, no longer uses released tars.

A new addition for KaOS is a First Run Wizard. It will run on the newly installed system and enables with just a few clicks to adjust mouse behavior, menu launcher, desktop theme, used wallpaper, color scheme, widget style, window decoration and virtual desktops used. With one click this Wizard will also link to KaOS Documentation and all contact info.

Another first on this ISO is a new tool to write ISO files to USB. Not only does IsoWriter write to USB it also gives the option to recover your USB stick after using it for an ISO, something that regular dd copy or the previously used Imagewriter were not able to do.

The Plasma Desktop includes Frameworks 5.26.0, Plasma 5.7.90, KDE Applications 16.08.1 & not yet released ports of KDE Applications. All built on Qt 5.7.0.

The installer now automates setting your location on the world map and has improved volume scanning so it won't show live USB or optical drives as install options.

For Plasma 5.8 the used Midna theme has been updated in many parts, this includes on all new SDDM theme, new gfxboot splashscreen, redone panel launchers, updated Logout and Lock screen, several new icons, including icons for the system tray.

Most notable major updates to the base of the system are a Boost 1.61.0, FFMPEG 3.1.3, Linux 4.7.4, Systemd 231, Poppler 0.47.0, Python 3.5.2, Gstreamer 1.8.3, Protobuf 3.0.0 and MariaDB 10.1.17

KaOS repositories no longer provide Qt 4. It is a good three years ago that development for Qt 4 stopped, late 2015 all support including security fixes ended. Any application that has not made the transition to Qt 5 in all this time can no longer be supported in KaOS. Either they actually are no longer maintained or their development is ignoring the implications of building on a possible insecure toolkit.

The Linux kernel has all the needed ucode build-in for a fully automated Early Microcode update.

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.

It is possible for both the Live session and installed system to start a Plasma Wayland session right from the login manager. An X11 session is of course still default, but the drop-down menu has a Wayland entry too. With Plasma 5.8, the Wayland session is now possible on more systems.

KaOS uses the Systemd provided Systemd-boot for UEFI installs

Calamares, the used installer framework, has moved to the 2.4 series. Highlights of the changes and additions:

• Fixed how the timezone setting is applied, so certain environments always obey the setting on first boot
• Fixed timezone selector behavior, so that a timezone changes affect the live system immediately
• Rewritten large portions of the locale module, with new locale and timezone autodetection functionality and smarter management of locale.conf values
• Fixed a user name validation issue which could in some specific situations cause a failed installation
• Added support for generating /etc/crypttab, this relies on a single master passphrase.

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.

This ISO presents XFS as the default filesystem option for KaOS.

To learn more about the goals and ideas behind KaOS, please read the Home, About and FAQ pages.

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 FAQ. A rolling release distribution never has a "final" release, every ISO is mere a snapshot of the current status of the repositories. An idea what is currently available:

The ISO ships with Frameworks 5.26.0, Plasma 5.7.90, KDE Applications 16.08.1 & not yet released ports of KDE Applications, Linux 4.7.3, Systemd 231, Kmod 23, NetworkManager 1.4.0, Calligra 3.0Alpha, Krita 3.0.1, Cantata, Plasma-nm 5.7.90, Xorg-server 1.18.4, Mesa 12.0.2, Glibc 2.23, GCC 5.4.0, non-free Nvidia 371.28, Pepperflash and Python3 3.5.3 to name a few.

The package manager is Pacman 5.0.1, with the simple but powerful Octopi 0.9dev as GUI frontend. Default web browser is Qt based Qupzilla 2.0.0. GFXboot is included with KaOS artwork, Grub theme is Midna, Look & Feel is a KaOS exclusive version "Midna", fully redone for 2016.

Repositories of KaOS will stay limited in size and expect it to stay at the current maximum of about 2100-2200. A gist of what is available, besides the stable kernel there is Linux-next 4.8, Libreoffice 5.2.1, Qt 5.7.0, bumblebee packages, VLC, Vokoscreen, Blender, XBMC, Calibre, Sigil, Librecad, a few games like 0ad and Knights.
A limited number of the most well-known GTK applications are available, examples Firefox 48.0.2, Chrome 55, Ardour 5.3.0, Inkscape 0.91, GIMP 2.9.4 and Google-talkplugin 5.38.5.0.
Complete language packs are available for KDE, Calligra, Firefox, Libreoffice and Thunderbird. For IM, Fcitx 4.2.9.1 is available as a rather complete group.

Known issues:

• On systems running the Nouveau graphics driver, Qupzilla will not start. Either install the non-free nvidia driver or use another browser. Nouveau is not compatible with QtWebEngine.
• If you do not want to install a bootloader, do not use any of the automated partitioning options, select manual for this. See the bug report for the installer regarding this.
• If you want to use a GPT partition table on a BIOS system, make sure to set it up following this Guide, the installer's partitioner can only handle GPT correctly for UEFI
• Installing on RAID or LVM is currently not possible
• Hibernate on LUKS enabled swap partitions needs manual intervention, the installer misses some settings to fully support this

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.
