What is COSMIC Desktop Environment?
COSMIC, which stands for Computer Operating System Main Interface Components, is a modern desktop environment designed by System76, the popular computer manufacturer specializing in Linux-powered systems.
Built from the ground up using the Rust programming language, COSMIC prioritizes stability, security, and performance, aiming to provide a refined and highly customizable desktop experience for users.
Initially developed only for the Pop!_OS Linux distribution, COSMIC has evolved into a versatile desktop environment available for a variety of Linux distributions.
COSMIC desktop features a modular architecture that allows distributions to tailor the interface with their brand colors and preferred settings. Distributions can easily modify panels, docks, applets, and even core settings pages to create unique and personalized user experiences.
While still in alpha, COSMIC is already getting significant attention for its unique features and sleek design.
It distinguishes itself from traditional desktop environments with its auto-tiling window management, robust theming system, and a suite of new core applications, including a dedicated app store.
Users can effortlessly switch between tiled and floating window layouts, personalize their desktop with custom themes and wallpapers, and enjoy a cohesive workflow across all applications.
COSMIC Desktop Features
Key features of COSMIC include:
- Empowered Workflow: Customize panels, docks, and workspaces to fit your workflow.
- Adaptable Windows: Choose between tiled, floating, or mixed window arrangements for optimal productivity.
- Enhanced Theming: Personalize your desktop with custom themes and wallpapers.
- Robust Applications: COSMIC includes core applications like Files, Settings, Terminal, Text Editor, and an App Store.

Now, Let's discuss what's new in the COSMIC alpha 5 release.
Introducing COSMIC Media Player
You can now say goodbye to the external media players! COSMIC Alpha 5 introduces its own built-in media player.
While still in its early stages, it leverages Vulkan for rendering and VAAPI for decoding for smooth and efficient video playback.
Audio playback is on the roadmap for upcoming updates.
Smoother Multitasking with Enhanced Alt+Tab
Navigating between applications is now more intuitive with the updated Alt+Tab and Super+Tab functionality.
These shortcuts now cycle through open applications based on their last active order. This means you can quickly switch to the app you were just using without cycling through the entire list.
Variable Refresh Rate Gets a Boost
For users with VRR-capable displays, COSMIC Alpha 5 brings refined VRR handling, taking into account your display's minimum refresh rate. This ensures a smoother cursor experience, especially noticeable in full-screen applications.
Effortless User Management
Managing user accounts is now simplified with the new Users Settings page. This centralized location lets you view all user accounts, change usernames and passwords, and even toggle admin permissions for other users.
Other Notable Improvements:
- Open links directly in COSMIC Terminal by simply clicking on the URL.
- Improved ContextDrawer navigation with header buttons for easier file browsing.
- A number of bug fixes and refinements addressing issues like monitor screenshots, file saving, context menu behavior, and more.
