How To Install COSMIC Desktop Environment On Fedora 40

System76's COSMIC Desktop Environment (DE): A Deep Dive and Fedora 40 Installation Guide

System76, the creators of the popular Pop!_OS Linux distribution, have unveiled COSMIC DE, a new desktop environment built from the ground up. This tutorial provides a comprehensive overview of COSMIC DE's features and a step-by-step guide to installing it on Fedora 40.

What is COSMIC DE?

COSMIC (Computer Operating System Main Interface Components) is a modern, customizable desktop environment written in Rust using the Iced GUI library. Initially introduced with Pop!_OS 21.04, it's designed to improve upon the GNOME Shell experience with a refined and highly configurable interface. Unlike Pop!_OS's current GNOME-based desktop, COSMIC is a ground-up project, offering greater flexibility and control. It's composed of independent components (compositor, libraries, applets) that can be updated individually. While currently in alpha, it's slated to become the default DE for future Pop!_OS versions.

Key Features of COSMIC DE:

COSMIC DE boasts several noteworthy features:

• Extensive Customization: Users can tailor panels, wallpapers, and functionalities to their liking.
• Intuitive Workspace Management: Streamlined workspace management for efficient task organization. Supports both vertical and horizontal workspaces.
• Enhanced Application Launcher: Quick access to applications and system utilities with integrated search.
• Custom Terminal (COSMIC Terminal): A high-performance terminal with bidirectional rendering, ligatures, and theming support.
• Frosted Glass Effect: A visually appealing aesthetic touch.
• Tiling Window Manager: Built-in tiling capabilities for enhanced productivity.
• Hybrid Graphics Mode: Efficient power management with hybrid graphics support.
• Custom Setup Utility: Simplified configuration of desktop settings.
• Top Navigation Bar: Clear separation of Activities (Applications) and Workspaces.
