Updated Linux Distributions

ReactOS is a free and open-source operating system based on the best design principles found in the Windows NT architecture. Written completely from scratch, ReactOS is not a Linux-based system and it shares none of the UNIX architecture. The main goal of the ReactOS project is to provide an operating system which is binary compatible with Windows. This will allow Windows applications and drivers to run as they would on a Windows system. Additionally, the look and feel of the Windows operating system is used, such that people accustomed to the familiar user interface of Windows would find using ReactOS straightforward. The ultimate goal of ReactOS is to allow people to use it as an alternative to Windows without the need to change software they are used to.

ReignOS is an Arch Linux-based gaming distribution. It boots into a graphical system installer which installs a base system, then downloads and installs all extra components after the first boot. The distribution offers a broad range of hardware compatibility by supporting various window compositors, including Steam's Gamescope, KDE's KWin, Wayland's Cage and Weston, and X.Org's X11. It also supports all popular GPUs (Intel, AMD, NVIDIA), as well as hybrid-graphics setups, mGPU and eGPU graphics processing units. ReignOS can boot into a standard KDE Plasma desktop, Steam gaming platform, or a custom-designed control centre that offers a choice user interface options.

openKylin is a Chinese desktop Linux distribution which runs the Kylin and UKUI desktop environments. Both Wayland and X11 sessions are available out of the box. The project is a member of the Debian family and can use APT package management tools. It also features a custom package format which is combined with a software centre. openKylin is also a proving ground for custom utilities which assist the user in managing the operating system.

FunOS is an Ubuntu-based Linux distribution which features the JWM graphical user interface. The project is intended to be more lightweight than official Ubuntu community editions while providing the same application compatibility and hardware support.

FreeBSD is a UNIX-like operating system for the i386, amd64, IA-64, arm, MIPS, powerpc, ppc64, PC-98 and UltraSPARC platforms based on U.C. Berkeley's "4.4BSD-Lite" release, with some "4.4BSD-Lite2" enhancements. It is also based indirectly on William Jolitz's port of U.C. Berkeley's "Net/2" to the i386, known as "386BSD", though very little of the 386BSD code remains. FreeBSD is used by companies, Internet Service Providers, researchers, computer professionals, students and home users all over the world in their work, education and recreation. FreeBSD comes with over 20,000 packages (pre-compiled software that is bundled for easy installation), covering a wide range of areas: from server software, databases and web servers, to desktop software, games, web browsers and business software - all free and easy to install.

Nobara Project is a modified version of Fedora Linux with user-friendly fixes added to it.

Nobara aims to fix most of those issues and offer a better gaming, streaming and content creation experience out of the box. The project's official release comes with a custom-themed GNOME desktop, but it also offers separate editions with standard GNOME and KDE desktops.

EndeavourOS is a rolling-release Linux distribution based on Arch Linux. The project aims to be a spiritual successor to Antergos, providing an easy setup and a pre-configured desktop environment on an Arch base. EndeavourOS offers both off-line and on-line install options. The off-line installer, Calamares, uses the KDE Plasma desktop by default. The on-line installer can install optional software components, including most popular desktop environments.

ZenLake OS is desktop Linux distribution, based either on Debian's "Stable" branch or Ubuntu's long-term support (LTS) release, featuring a customised GNOME desktop. Its goal is to create a minimal, but user-friendly and familiar desktop layout, with a taskbar at the bottom of the screen. The distribution also includes a built-in system restore functionality that can revert the system to a previous state in case of a boot or system failure.

Asmi Linux is a desktop-oriented Linux distribution with editions based on either Ubuntu or Debian. It uses a highly-customised Xfce desktop with some user-friendly touches.

At the live system's login screen, Kiro offers a choice between the Xfce desktop environment and ohmychadwm window manager (Kiro's own tiling window manager, a fork of dwm). Once installed, it provides support for a number of popular desktop environments and window managers, all installable from ArchLinux Tweak Tool. Kiro follows Arch's rolling-release model and targets 64-bit (x86_64) systems.

Xubuntu is a community-developed operating system based on Ubuntu. It comes with Xfce, which is a stable, light and configurable desktop environment.

Edubuntu is a partner project of Ubuntu, a distribution suitable for classroom use. The aim is that an educator with limited technical knowledge and skill will be able to set up a computer lab, or establish an on-line learning environment, in an hour or less, and then administer that environment without having to become a fully-fledged Linux geek.

An official variant of Ubuntu, Ubuntu Studio is a Linux-based operating system for creative individuals in the areas of audio production, video production, graphics design, photography and desktop publishing. It makes professional audio accessible on Linux; it uses the JACK sound server and a kernel built with a low-latency patch.

Ubuntu Budgie (previously budgie-remix) is an Ubuntu-based distribution featuring the Budgie desktop, originally developed by the Solus project. Written from scratch and integrating tightly with the GNOME stack, Budgie focuses on simplicity and elegance, while also offering useful features, such as the Raven notification and customisation centre.

Ubuntu Kylin is an official Ubuntu flavour whose primary goal is to create a variant of Ubuntu optimised for Chinese users (using the Simplified Chinese writing system), although it also supports other languages.
