Welcome to the #NXWorld

Hi there! Meet Nitrux.

Powered by Debian, KDE Technologies, and Qt.


Nitrux is made with by people like you.

Nitrux is a Linux desktop distribution directly based on Debian. It uses the Calamares installer and includes NX Desktop and NX Firewall on top of the KDE Plasma 5 desktop environment and KDE Applications. Nitrux emphasizes the use of AppImages to manage end-user software. Nitrux also does not use systemD as its init system; instead, it uses OpenRC.

Nitrux includes a suite of convergent applications called Maui Apps. We use MauiKit, our convergent, cross-platform UI framework, to create these applications. Both MauiKit and the Maui Apps are entirely free and open-source software.

In addition to this, we include a curated selection of free and open-source software by default; we don’t add proprietary software. And for those looking for a 100% free (as in freedom) operating system, the optional Linux Libre kernel is available to install.

Nitrux is always up-to-date, thanks to using the latest Debian base and to the effort of the KDE Neon developers, who provide the latest stable releases of Plasma. Nitrux also provides its users of the latest MESA drivers from Git, and kernels optimized for intensive tasks such as gaming with XanMod and Liquorix.

What could I use Nitrux for?

Well — just about anything! It can perform many functions that any computer could use. Surf the internet, word process, email, spreadsheets, listen to music, watch movies, chat, games, photo editing, content creation, whatever you want!.

Introducing NX Desktop.


We extend Plasma to allow the user to glance over system operations with easy to understand status displayed on the screen. NX Desktop is our set of applied customizations to the Plasma 5 Desktop. It includes new plasmoids (or widgets) and a new look and feel package (wallpapers, Plasma themes, Konsole theme and profile, Aurorae themes, SDDM themes, cursors, and color-schemes).

**NX Desktop is not a desktop environment. NX Desktop does not provide a file manager, web browser, multimedia player, email client, address book, PDF reader, photo manager, and system preferences application. 

Renewed System Tray

The System Tray replaces the traditional Plasma version.

Notification Center

For easy access to your notifications, the System Tray features an area specifically for them.

Quick access to networks

Easily access and edit your network preferences.

Easy multimedia controls

Combining the volume controls and the media controls of Plasma for simpler operation.

Everything you need to get started.

Nitrux is a complete Operating System that ships the essential apps and services for daily use: office applications, PDF reader, image editor,
music and video players, etc. Nitrux ships with select KDE Applications by default along with our own custom applications. KDE Applications are a set
of applications and supporting libraries that are designed for KDE Plasma 5. We also include non-KDE or Qt applications like Firefox and LibreOffice
that together create a friendly user experience.

Available out-of-the-box

Nitrux includes a selection of applications carefully picked to perform the best when using your computer:

Built with MauiKit

Index, the file manager.
Nota, a simple text editor.
Station, the terminal emulator.
Pix, an image gallery.
VVave, music player.
Buho, a note-taking application.
Communicator, an application to manage contacts.
Shelf, simple and light PDF viewer.
Clip, video player.

A great selection of Open Source software

Ark, archiving tool.
KCalc, calculator.
Plasma System Monitor, system task manager.
Spectacle, screenshot utility.
Latte, versatile dock application.
Firefox, ethical web browser.
LibreOffice, open-source office suite.
Inkscape, vector graphic editor.
GIMP, GNU image manipulation tool.

… and more!.

A free and modular front-end framework.


A set of templated controls and tools based on QQC2 and Kirigami shared among the Maui set of applications. MauiKit helps to quickly build UIs that follow the Maui HIG and bring ready to go tools for different platforms, such as Android and Linux. Seamless transition between mobile and desktop technology — where the line between desktop and mobile is blurred. Using the same codebase Maui Apps provide users with one app for multiple form factors. Accomplish in a few lines what would otherwise take hundreds, from concept to the end user’s screen — the fastest way to create convergent apps.


Components ready to easily use and that work on Android and Linux


Easily create applications that work in mobile devices and desktop computers.

Built with Kirigami

MauiKit is built using KDE Kirigami framework and Qt Quick Controls 2.

The fastest way to develop beautiful desktop and mobile apps

Experience streamlined development with zero-time setup, using the technologies you already know and love – Qt, QML and C++.

Brilliant look and feel with lots of ready-to-use components and styling

A rich variety of UI components specially designed for mobile and desktop apps. MauiKit provides tons of elements. They all have Linux and Android support. With MauiKit you can genuinely support both Android and Linux with the same source code.

Explore a universe of apps in Nitrux with AppImage.


AppImage provides a way for upstream developers to offer “native” binaries for Linux users just the same way they could do for other operating systems. It allows packaging applications for any standard Linux-based operating system, e.g., Ubuntu, Debian, OpenSUSE, RHEL, CentOS, Fedora, etc. AppImages come with all dependencies that cannot be assumed to be part of each target system in a recent enough version and will run on most Linux distributions without further modifications.

By bundling your application as an AppImage, you can provide an official download for Linux like you would for Windows and macOS, where you can the author control the end-to-end user experience with no intermediaries between you and the author and your end-user With just one AppImage, you can reach users of most Linux distributions. You can provide new download links as often as you like, e.g., for each continuous build.

Also, doing an AppImage has these advantages:

  • Just one format for all major distributions.
  • Works out of the box; no installation or runtimes needed.
  • No-root needed.
  • One app = one file = super simple for users.
  • Desktop integration with appimaged.
  • Binary delta updates, e.g., for continuous builds (only download the binary diff) using AppImageUpdate.
  • Can GPG2-sign your AppImages (inside the file).

Feeling lucky? Build yourself your version of Nitrux.

Our primary focus is to use KDE Plasma and MauiKit; however, we understand that it may not cater to fans of other desktop environments. And that different users may prefer to have an alternative selection of default applications than the ones we include by default. With that in consideration, we have made available the minimal ISO.

Nitrux is also available to advanced users as an alternative minimal ISO image built to serve users who want to install Nitrux but may prefer to use other desktop environments and software selection.

By default, this minimal image only includes SDDM, i3, Calamares, xterm, and X11. However, it does have our default selection of CLI tools and applications (cmus, ftp, hdparm, htop, links2, mc, ncdu, nsnake, tmate, tree), as well as appimage-cli-tool, appimagetool, Wine, etc.

If you like to personalize your Linux installations, take it for a spin.

Securing your desktop and workstation.


NX Firewall is a firewall tool for Linux uses the Qt toolkit. You can use the wizard to create a basic firewall, then streamline it further using the dynamic rules. You can open and close ports with a few clicks, or monitor your services giving access only to a select few. NX Firewall is an open source application that provides users with a graphical user interface (GUI) for the ufw (Uncomplicated Firewall)/iptables command-line interface, which lets users manage Linux kernel’s packet filtering system.

Key features include the ability to use profiles, quickly enable or disable the firewall, easily set incoming and outgoing rules and view which applications are listening on which ports, as well as to effortlessly add or remove rules. With a single click of a button, users will be able to enable or disable the firewall as well as to set incoming and outgoing rules (Allow, Deny, Reject). It is also possible to easily create rules as well as to add simple or advanced firewall rules, where you can set default policy, category, subcategory and application.

Under the hood, the software is written entirely in the C++ programming language. However, its graphical user interface is written using the QML GUI toolkit. It is available as a KCM for the Plasma 5 desktop environment.

Automate version and backup sync of your files.

Kup is created for helping people to keep up-to-date backups of their files. Connecting a USB drive is the primary supported way to store data, but saving files to a server over a network connection is also possible for advanced users.

A detailed list of features

  • Backup types:
    • Synchronized folders with the use of “rsync.”
      Incremental backup archive with the use of “bup.”
  • Backup destinations:
    • Local filesystem monitored for availability. That means you can set a destination folder which only exists when perhaps a network shared drive is mounted, and Kup will detect when it becomes available.
    • External storage, like USB hard drives. Also monitored for availability.
  • Schedules:
    • Manual only (triggered from tray icon popup menu)
    • Interval (suggests new backup after some time has passed since the last backup)
    • Usage-based (suggests new backup after you have been active on your computer for some hours since the previous backup).

In general Kup tries to not disturb you needlessly.
