This Week in TUXEDO OS #14-2026 - TUXEDO Computers

Hello TUXEDO Fans and Open-Source Enthusiasts!

The latest figures from the Steam Linux Data Tracker reveal a trend Linux enthusiasts have been anticipating for years: after the usual seasonal dip at the start of the year, Linux usage has rebounded strongly, surpassing the five percent mark for the first time. At exactly 5.33%, Linux has reached a new high, highlighting the accelerated growth of recent months.

The picture becomes even more striking when looking at English-speaking Steam clients, where Linux now accounts for an impressive 11.28%. This indicates that Linux is growing particularly fast among tech-savvy users and is increasingly establishing itself as a serious gaming platform.

Notably, this growth isn’t primarily driven by new hardware like the Steam Deck. Valve isn’t currently selling new devices, and a next generation of Steam Machines is still pending. The increase appears to be largely organic, fueled by better software, more stable drivers, and an increasingly mature Linux gaming experience.

For Linux gaming, the message is clear: here to stay. For Easter, we’ve filled this TWIX with plenty of little surprises you can enjoy without even searching. In this edition, we feature Recorder as our App of the Week and show in the tips section how to customize your KDE Plasma start menu exactly the way you want.

Enjoy reading,
The TUXEDO OS Team

KDE App of the Week: Recorder – Spontaneous Audio Recording, Now on Plasma Mobile

This week, we take a closer look at Recorder (internally known as KRecorder), a young application from the KDE ecosystem that perfectly reflects the project’s convergent approach. The app is designed to work reliably and consistently on both traditional desktop systems and mobile devices with touch input, showcasing how modern KDE applications are conceived and implemented across platforms.

What is Recorder?

Recorder is a lightweight, Kirigami-based application for audio recording. Its focus is on simplicity and direct use: start, stop, save – in many cases, that’s all you need. The app deliberately avoids complex settings or extensive project management. Instead, it offers a clean, well-structured interface that is intuitive to use with both mouse and keyboard as well as touch.

What can Recorder do?

Despite its minimalist approach, Recorder provides all the essential functions needed for everyday use. You can start and stop recordings with just a few clicks, select your preferred input device if needed, and save your recordings in common audio formats. Recorded files can be managed and played back directly within the app. The interface is deliberately kept simple, with large controls and clear navigation – a particular advantage on smaller screens or when using Plasma Mobile.

Typical Use Cases

Recorder excels wherever speed is essential. Whether it’s spontaneous voice memos, short interviews, or quick recordings without preparation, the app is designed for these situations. Unlike more complex audio programs like Audacity, the focus is not on post-production but on immediate access to the recording function.

Installation

Recorder is not installed by default on TUXEDO OS but can easily be added via the Discover software manager. Alternatively, you can install it directly from the terminal:

sudo apt update && sudo apt install krecorder

As part of the KDE ecosystem, Recorder integrates seamlessly into existing Plasma environments, benefiting from their consistent design and integration.

Conclusion

Recorder is a deliberately streamlined tool that focuses on the essentials, and it excels precisely because of that. If you want to record audio quickly and without configuration overhead, it offers a modern, efficient solution from the KDE world.

TUXEDO OS Tips & Tricks: Customize Your KDE Plasma Start Menu

The easiest way to install software is through the Discover software manager. On TUXEDO OS, this not only ensures automatic updates but also integrates applications neatly into your desktop environment’s start menu. Programs are automatically assigned to categories like Utilities, Graphics, or Internet.

But what if you prefer a different organization? Maybe you want LibreOffice Draw grouped with the other LibreOffice apps under Office instead of Graphics. No problem: KDE Plasma gives you extensive options to tailor the application menu exactly to your needs. You can change categories, move entries, or even create entirely new menu structures.

The KDE Menu Editor

To customize, open the KDE Menu Editor by right-clicking the TUXEDO icon in the panel and selecting Edit Applications…. Within the editor, you can create new entries, submenus, or separators, as well as reorder existing programs or assign them to different categories. All changes apply only to your user account and do not affect the system globally.

Add your own programs via New » New Item…. Assign a name, optionally a description, and specify the path to the executable either manually or through the file selection dialog. You can also choose a suitable icon to make the entry visually appealing.

The Advanced tab is particularly useful: here you can enable Run using dedicated graphics card to run applications on the more powerful GPU. This is especially beneficial for games, video editors, or 3D applications, ensuring maximum performance on suitably equipped systems.
