Hello TUXEDO Fans and Open-Source Enthusiasts!
Anyone with several years of Linux experience remembers how complicated it used to be to install the latest program versions. It would have been nice if simply compiling the source code had been enough. In most cases, however, you also had to install a whole series of libraries – often compiling them yourself – whenever the distribution didn’t provide the required up-to-date versions. This led to the dreaded „Dependency Hell.“
Today, thanks to image formats like Ubuntu’s Snap, AppImage, and especially Flatpak , such problems are a thing of the past. The latest Applications can be installed with a single click and are automatically updated in the background. Developers benefit as well: Flatpaks are distribution-independent, don’t need to be adapted for every Linux variant, and run in a sandbox that protects the system – unlike AppImages, which have full system access.
In the 2025 year in review , the Flathub app repository reported almost 440 million downloads, an increase of over 20 percent compared to 2024. The number of available apps grew by 446 to a total of 3,249. In total, 727 million updates were carried out via Flathub in 2025. Top downloads included Firefox (2.7 million), Chrome (2.4 million), and Discord (2.1 million). Among games, Sober, Minecraft, and Space Cadet Pinball dominated – yes, the classic pinball from Windows 95.
In TUXEDO OS, access to Flathub is also integrated directly. Simply open the Discover software manager: an icon indicates the source of each result, and a single click is all it takes to install the program immediately. As part of TWIX, we regularly introduce applications that are most comfortably installed this way. With that in mind, we’re excited to see what the open-source universe has in store for us this year.
Enjoy reading,
The TUXEDO OS Team
Note: We would like to keep you updated on the latest developments in TUXEDO OS with the TWIX series and introduce you to exciting applications as well as practical tips related to the KDE desktop and TUXEDO OS. However, this section should not be a one-way street: your feedback, ideas, and suggestions for improvement are very welcome! For this purpose, we have created a thread on Reddit, where you can reach us directly.

KDE App of the Week: Marknote – Capture Notes in Markdown
Notes help us organize our thoughts and keep important information for later in our often hectic daily lives. With Marknote , we introduce a KDE app that works on both desktop and mobile devices.
Marknote is a simple WYSIWYG note-taking app from KDE that creates text in Markdown and organizes it in freely configurable notebooks. All notes are stored as editable Markdown files in your Documents folder, allowing seamless integration with KDE Plasma and Plasma Mobile.
The young application was first introduced in 2024 by KDE developer Mathis Brüchert and is built using the Kirigami framework. Marknote supports formatting such as bold, italic, underline, and strikethrough, headings, lists, tables, images, task lists, and simple sketches.
Marknote lets you quickly create and manage Markdown notes in notebooks that can be customized with colors and icons, integrating nicely into KDE Plasma.
Notebooks can be individually styled with icons and accent colors. Additionally, undo and redo functions, clickable links, and selectable fonts and themes are available. Content can be exported as PDF, HTML, or ODT. You can also import notes from KNotes or directories in Maildir format .
Installation
Marknote is not preinstalled in TUXEDO OS but is available in the Discover software store as a Debian package or Flatpak. Alternatively, you can install it via the terminal:
sudo apt update && sudo apt install marknote
The current version is 1.3. On the desktop, you can flexibly adjust the width of the note list and editor. On mobile devices, the editor toolbar can be hidden if needed, keeping formatting options just a tap away.
Info: Are you interested in Plasma development and want to know what new features are planned and which programs have been recently updated? You can find a detailed overview in the weekly column This week in Plasma by KDE developer Nate Graham.
TUXEDO OS Tips & Tricks: Better Tiling with Mouse Tiler
It’s a bit paradoxical: no matter how large your monitor is, there never seems to be enough space to arrange application windows efficiently – especially when juggling multiple apps at once. To bring a little order to larger displays, the KDE Plasma desktop in TUXEDO OS already includes a simple tiling feature.
Drag a window to the left or right edge of the screen, and it docks to half of the desktop. Drag it to the top, and it automatically maximizes. Move a window into one of the four screen corners, and it fills a quarter of the screen. This makes it easy to work with multiple applications simultaneously – for example, a browser on the left while an editor and terminal share the right side.
Next-Level Tiling with Mouse Tiler for KDE
For those seeking more advanced window arrangements, many turn to specialized tiling window managers like Hyprland , Sway , or Niri . However, these usually require extensive configuration and differ significantly from the familiar workflow of a classic desktop environment. If you prefer to stay with the KDE desktop but want more tiling options, check out the KWin script Mouse Tiler .
KDE Plasma’s tiling features compared to Mouse Tiler: The KWin script shows a popup that lets you precisely arrange and adjust windows on a grid.
You can install the extension via the System Settings under Window Management » KWin Scripts . Click Get New… in the top-right corner, search for „Mouse Tiler“, and install it. Then activate Mouse Tiler in the list of installed scripts and click Apply . At first glance, nothing seems to change. But as soon as you move a window by its title bar, an overlay appears with various options for arranging the window.
Mouse Tiler can be installed conveniently via the built-in KWin script manager in System Settings, without manually downloading additional packages.
After installation, activate the Mouse Tiler script directly in System Settings so that the additional tiling features are available on your KDE desktop.
Mouse Tiler’s extensive settings allow detailed customization of the script for your workflow, including layouts, display options, and input methods.
Mouse Tiler in action: When you move a window by its title bar, an overlay appears that lets you precisely arrange the window on the screen.
To control Mouse Tiler via keyboard, open the settings through the sliders icon and switch to the Shortcuts tab in the configuration dialog. Here you’ll find instructions for setting up keyboard shortcuts, which currently aren’t created automatically. Go to System Settings » Keyboard » Shortcuts » Window Management and search for „Mouse Tiler“. Then assign the following key combinations:
Mouse Tiler: Change Mode : [Meta] + [Ctrl] + [Space]
Mouse Tiler: Show All / Toggle Span : [Ctrl] + [Space]
Mouse Tiler: Show Config : [Ctrl] + [.]
Mouse Tiler: Toggle Input Type : [Ctrl] + [Alt] + [I]
Mouse Tiler: Toggle Visibility : [Meta] + [Space]
To control Mouse Tiler via keyboard, the desired shortcuts must currently be set manually in System Settings under the window management shortcuts.
The developer of Mouse Tiler is also working on another KWin script called Remember Window Positions . This script saves application window positions when a program is closed or the computer is shut down and restores them on the next launch – including their assignment to virtual desktops. Combined with Mouse Tiler, this creates a very efficient workflow: applications have a fixed place and can be found again quickly.
