COSMIC DE is a new, full-featured desktop environment (like GNOME and KDE) written from scratch in the Rust programming language. It does not rely on GTK or Qt. Instead COSMIC uses a new Rust GUI toolkit called iced and the system76 developed libcosmic toolkit for building interfaces and applications with advanced theming and customization features.

COSMIC DE includes a suite of first-party applications including a file browser, text editor, application store, settings, and terminal. There is also a growing community of third-party apps. COSMIC includes a custom compositor that features variable refresh rate, Xwayland support, animations, fractional scaling, modern hybrid graphics features, window snapping and auto-tiling.

What makes COSMIC truly unique is that it's the first modular, composable desktop environment. For a user that means they can easily adapt COSMIC to their preferred workflow. Linux distributions can create wholly unique user experiences.
And companies can develop unique products using COSMIC.

Carl will discuss why system76 built COSMIC DE, show its features, and demonstrate how unique experiences can be composed with COSMIC DE.
