System76 has released the highly anticipated Pop!_OS 24.04 beta, featuring the company’s completely rebuilt COSMIC desktop environment written in Rust. The new beta represents the most significant update to the Ubuntu-based Linux distribution in years, offering improved performance, enhanced customization, and a fresh user experience that challenges established desktop paradigms.

From Humble Beginnings to Revolutionary Desktop
System76’s journey with Pop!_OS began over a decade ago as a customized take on Ubuntu and GNOME, designed specifically for the company’s hardware. The distribution gained popularity for its reliability, ease of use, and thoughtful customization options. However, until recently, updates primarily focused on incremental improvements rather than transformative changes.
The landscape shifted dramatically in 2021 when System76 announced it was building COSMIC (Computer Operating System Main Interface Components) from scratch using Rust. This decision marked a bold departure from modifying existing desktop environments. According to System76’s official development roadmap, the company aimed to create “a desktop environment that is fast, stable, and customizable while maintaining compatibility with existing Linux applications.” The move to Rust programming language, known for memory safety and performance, positioned COSMIC as a modern alternative to traditional desktop environments.

Beta Experience: Challenges and Triumphs
Early adopters of the Pop!_OS 24.04 beta have reported both challenges and remarkable successes. The upgrade process from version 22.04 presented hurdles, particularly for users with encrypted drives who encountered UUID access errors during boot. However, System76’s integrated rescue partition provided a straightforward solution through refresh installations that preserved user data and customizations.
Once operational, users discovered a polished desktop environment that surpassed expectations for beta software. The COSMIC desktop demonstrated exceptional theming capabilities, consistently applying visual styles across both system and third-party applications. Performance metrics from Phoronix benchmarks show significant improvements in application launch times and system responsiveness compared to previous Pop!_OS versions. The new Pop Store replacement for the problematic Pop Shop delivers near-instantaneous loading and application installation regardless of package format—APT, Snap, or Flatpak.
Technical Innovations and Performance Benefits
COSMIC’s foundation in Rust programming language delivers tangible performance advantages that users immediately notice. The language’s focus on zero-cost abstractions and memory safety without garbage collection translates to faster application launches and smoother system operations. Independent testing by OMG! Ubuntu confirms that COSMIC outperforms many established desktop environments in responsiveness and resource efficiency.
The desktop environment introduces innovative workflow enhancements while maintaining compatibility with existing Linux applications. System76’s decision to build from scratch allowed them to implement modern graphics protocols and efficient rendering techniques. According to the COSMIC GitHub repository, the environment leverages advanced compositing and hardware acceleration to reduce latency and improve visual fluidity. These technical improvements come alongside robust stability, with beta testers reporting minimal crashes or system freezes despite the software’s development status.
Open Source Development Advantages
Pop!_OS 24.04’s rapid progression from alpha to beta status highlights the advantages of open source development models. Unlike proprietary operating systems that typically follow annual or multi-year release cycles, Pop!_OS receives regular updates that continuously improve stability and add features. The COSMIC compositor repository shows daily commits from developers worldwide, accelerating bug fixes and feature implementation.
This collaborative development approach enables faster response to security vulnerabilities and user feedback. Data from the Linux Foundation’s open source participation guide indicates that distributed development teams can address critical issues up to 70% faster than centralized proprietary teams. The constant iteration cycle means that Pop!_OS 24.04 beta improves with each update, gradually transitioning toward a stable release that could challenge mainstream operating systems.
Future Outlook and User Recommendations
For users considering testing the beta, System76 recommends installation on secondary machines or virtual environments while acknowledging the software’s surprising stability for daily use. The company’s official installation guide provides detailed instructions for both clean installations and upgrades from previous versions. Early adopters should expect occasional issues but can participate in shaping the final product through bug reports and feedback.
The successful beta release positions COSMIC as a potential game-changer in the Linux desktop landscape. With its combination of modern programming language, thoughtful design, and rapid development cycle, COSMIC demonstrates how focused open source projects can compete with and potentially surpass established alternatives. As the development team continues refining the environment, Pop!_OS 24.04 represents not just another Linux distribution update, but a significant step forward in desktop computing evolution.
