Manjaro 25.0 “Zetar”: A Bold Leap into Flatpak Integration and Gaming Optimization

Linux Journal
2 months ago
by George Whittaker

Manjaro Linux has long been celebrated for blending the power of Arch Linux with user-friendly features. With the release of Manjaro 25.0 “Zetar”, the distribution takes significant strides in enhancing application management through Flatpak integration and optimizing the system for gaming enthusiasts. This update also brings advancements in desktop environments, file system choices, and hardware support.

Flatpak Integration: Streamlining Application Management

One of the standout features of Manjaro 25.0 is its enhanced support for Flatpak, a universal package management system. This integration allows users to install and manage applications in a sandboxed environment, improving security and ensuring that applications have access only to the resources they need. The inclusion of Flatpak support means users can easily access a vast repository of applications, including those not available in traditional repositories, directly through the Pamac package manager.

Gaming Enhancements: A Focus on Performance

Manjaro 25.0 places a significant emphasis on gaming, introducing several features aimed at improving performance and compatibility:

  • Linux Kernel 6.12 LTS: The default kernel in this release offers improved hardware support, including better compatibility with newer GPUs and CPUs, which is crucial for gaming performance.

  • Enhanced Graphics Support: Updates to graphics drivers, including the latest Mesa and NVIDIA drivers, ensure that gamers have access to the most recent improvements and bug fixes.

  • Manjaro Summit Initiative: Although still in its alpha phase, the Manjaro Summit project introduces a semi-immutable version of the distribution, aiming for greater system stability and consistency—an essential factor for gaming systems.

Desktop Environment Updates: GNOME 48, KDE Plasma 6.3, and Xfce 4.20

Manjaro 25.0 offers updated versions of its three main desktop environments, each bringing unique enhancements:

GNOME 48

  • Notification Stacking: Improves organization by grouping notifications from the same application.

  • Dynamic Triple Buffering: Enhances animation smoothness and reduces screen tearing.

  • Battery Charge Limiting: Introduces an option to cap battery charging at 80%, prolonging battery lifespan.

  • HDR Support: Initial support for High Dynamic Range displays, offering richer visuals.

KDE Plasma 6.3

  • Improved Fractional Scaling: Provides sharper visuals on high-DPI displays.

How Questing Quokka (25.10) Ushers a New Era of Rust-Based Tools

Linux Journal
2 months 1 week ago
by George Whittaker Introduction: A New Chapter for Ubuntu

Ubuntu 25.10, affectionately codenamed Questing Quokka, represents more than just the latest iteration of Canonical’s flagship Linux distribution. It marks a decisive step towards modernizing the foundation of Ubuntu by integrating Rust, a systems programming language renowned for its safety, performance, and modern design. This bold move signals Canonical’s commitment to security, reliability, and future-proofing its desktop and server operating systems.

The release of Questing Quokka aligns with a growing trend across the Linux ecosystem: embracing Rust as a key technology for building low-level components. But what does this mean for Ubuntu users and developers? Let’s explore the significance of this change, what tools are being rewritten or introduced in Rust, and how this positions Ubuntu for the future.

Why Rust? The Language of Safety and Speed The Need for Safer Code

For decades, core components of Linux distributions—including Ubuntu—have been written predominantly in C. While C offers unmatched control and performance, it also exposes developers to a range of memory-related errors: buffer overflows, use-after-free bugs, and data races, to name a few. These flaws are among the leading causes of vulnerabilities that compromise system security.

Rust was designed specifically to address these issues. It offers:

  • Memory safety without garbage collection: Rust’s ownership model and borrow checker ensure that memory errors are caught at compile time.

  • Fearless concurrency: Developers can write multithreaded code that’s safe by default.

  • Modern tooling and ecosystem: A robust package manager (Cargo), modern build tooling, and vibrant community support.

Linux and Rust: A Growing Bond

Ubuntu is not alone in recognizing Rust’s advantages. The Linux kernel itself has started to accept Rust code, with drivers and modules being prototyped in Rust to enhance safety. Projects like GNOME, System76’s COSMIC desktop, and various networking utilities have already begun leveraging Rust.

By adopting Rust-based tools, Canonical is aligning Ubuntu with this broader movement—ushering in a future where critical system software is both fast and secure.
