Hello TUXEDO Fans and Open-Source Enthusiasts!
Tux-tastic news have reached our igloo office: PewDiePie, the YouTube star with over 110 million subscribers, is now using Linux! Here is the link to his video. To celebrate the occasion, we had mackerel champagne and squid hors d’oeuvres from Fine Foods FOSS. In keeping with the good vibes, we present the KDE Jukebox JuK in this issue – and show you ten handy keyboard shortcuts to make TUXEDO OS even more efficient.
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: The KDE Jukebox or Simply JuK
The conclusion of our small series on media players for the KDE desktop is JuK , an audio player with a long development history spanning 25 years. Like Amarok, JuK is a jukebox player designed specifically for managing large music collections. The application supports common audio formats such as MP3, FLAC, Ogg Vorbis, and Musepack (MPK).
Features
JuK offers a variety of practical features that make managing large music collections easier. Notably, it allows you to create and manage playlists, which can even be based on custom searches. This makes it easy to organize your music collection and play it as you like. Metadata management also plays a key role, enabling you to quickly edit and keep up-to-date all the relevant information about titles, artists, and albums.
Here you can select the folders to be included in your music collection when you first start JuK.
For an appealing visual presentation, JuK offers cover management that automatically loads album covers via Google Image Search, making browsing through your collection even more enjoyable. Additionally, JuK has a useful feature for renaming files based on metadata, ensuring that music files are always correctly and neatly named. Other features include shuffle play, automatic updating of the entire music database, folder monitoring, and the integration of MusicBrainz for title identification.
Additional Features
Shuffle play
Collection list for displaying and automatically updating the entire music database
Folder monitoring by the user
Playback queue
Playback history
Integrated MusicBrainz support for online title identification
Scrobbling to Last.FM
First Program Start
When you first launch JuK, you have the option to select the folders to be included in your collection and specify which ones to exclude. After a short while, you can start browsing your music collection. The user interface of JuK is designed to allow efficient management of your collection. Visual effects such as album cover displays take a backseat. Instead, JuK shows lyrics, if they are available in the metadata (e.g., ID3 tags for MP3 files). The tag editor and search function can be accessed through the toolbar.
JuK quickly reads even large music collections and provides a clear overview of titles and metadata.
Installation
JuK is not pre-installed by default on TUXEDO OS but can be easily added. You can install the application via the Discover app or through the terminal. In Discover , you can choose between the native Debian package or the Flatpak format.
TUXEDO OS Tips & Tricks: Ten Useful Keyboard Shortcuts for Everyday Use
KDE Plasma offers numerous ways to work efficiently. In this issue, we present ten practical keyboard shortcuts that help you navigate TUXEDO OS more quickly and effectively. All mentioned shortcuts can be customized or extended in the System Settings under Shortcuts .
Note: On Linux, the Meta key usually refers to the Super or Windows key, located to the left of the space bar. On your TUXEDO device, this key typically features a Tux logo. We therefore refer to it as the Tux key.
Alt + Tab – Switch Between Windows
Pressing Alt + Tab lets you quickly switch between your most recently used windows. Hold Alt and tap Tab repeatedly to cycle through all open windows. This makes multitasking easy, even if your screen has limited space.
Quickly and efficiently switch between open applications – ideal for multitasking at work or on the go.
Ctrl + Shift + V – Paste Text Without Formatting
This combination pastes copied text without any formatting – especially useful when inserting content from websites or PDFs. When pasting into LibreOffice Writer, you can choose between Unformatted Text and HyperText Markup Language (HTML) .
Clean and consistent text formatting – especially useful when pasting from browsers, PDFs, or other documents.
Tux + L – Lock Your Screen
Quickly protect your session: Tux + L instantly locks your screen. This is especially useful in public spaces or offices when stepping away from your computer. While some colleagues may only change your language settings for fun, others might take things more seriously—better safe than sorry.
Protects your session from unauthorized access – just press it when stepping away from your device.
Tux + Period – Open Emoji Picker
Use Tux + . to open KDE Plasma’s system-wide emoji picker. You can scroll or search for emojis directly. Perfect for apps like Tokodon for Mastodon that don’t include their own emoji keyboard.
Quickly insert emojis – system-wide support, ideal for chats, emails, or creative messages.
Tux + Plus/Minus – Zoom In or Out
In a Wayland session, you can easily zoom in and out of the screen by holding down Ctrl and Tux while scrolling the mouse wheel. The zoomed area automatically follows the mouse pointer, allowing you to work seamlessly. Mouse clicks and text input continue to function as usual. Alternatively, use Tux ++ or Tux +- . Pressing Tux += resets the zoom level.
Perfect for presentations or making small content more readable – the zoom follows your cursor.
Tux + Shift + Print – Screenshot a Selection
With Tux + Shift + Print , you open Spectacle directly in rectangular selection mode. Just mark the area with your mouse. You can then annotate the screenshot right away. On laptops, you might also need to press FN for the print key.
Flexible screen capture with selection tool – ideal for documentation or sharing specific parts of your screen.
Tux + Arrow Keys – Snap Windows
Use Tux + arrow keys to snap windows to the screen edges – perfect for working side-by-side with multiple applications. Make full use of your screen space, especially on large displays. Use Tux + Page Up to maximize a window again.
Precisely position windows on screen – great for split views while multitasking.
Alt + Space – Open Krunner
Krunner is a powerful tool for quick commands, app searches, and more. Press Alt + Space at any time to access it and execute actions or find content without detours. To access active Firefox tabs, you’ll need to grant additional permissions – just click the button provided.
KDE’s versatile search and command tool – launch apps, calculate, or find files in seconds.
Ctrl + Alt + T – Open a Terminal
Press Ctrl + Alt + T to instantly open a terminal window for system commands or configuration tasks. In TUXEDO OS, this launches Konsole by default. Don’t worry: While you can do everything in the terminal on TUXEDO OS, you definitely don’t have to.
A handy shortcut for regular terminal users – instantly ready for commands.
Tab in Terminal – Command Completion
Type part of a command or filename and press Tab . The terminal will autocomplete it or show matching suggestions. Especially helpful with long filenames or cryptic package names. If you’re using a shell like Fish, command completion becomes even more powerful.
Work faster with intelligent auto-completion – reduces typing errors and saves time with long names.
These keyboard shortcuts help you use TUXEDO OS more effectively and with greater precision. Do you have your own favorite tips? We’d love to hear from you – and may include them in a future newsletter.
