System76 kicks off 2025 with a new COSMIC Alpha release! Our team is rested and racing towards an approaching Beta of our new Rust-based desktop environment for Pop!_OS and other distros. COSMIC Alpha 5 brings an early version of the COSMIC Media Player, Users Settings, and essential updates to Alt+Tab, variable refresh rates, and more!

COSMIC Media Player

COSMIC Media Player is now the default media player. We’re also developing a COSMIC-native codec installation application to replace sessioninstaller. While still a work in progress, COSMIC Media Player uses vulkan for rendering and vaapi for decoding (where available) for efficient video playback. Audio playback is supported as well.

Alt+Tab recency ordering

Cycling through your open apps using Alt+Tab or Super+Tab will now cycle the apps in the order they were last active. Hold Alt or Super to select the app from the Launcher using Tab, or quickly press and release the shortcut to jump to the most recent active window. To cycle between apps in reverse order, use Alt (or Super) + Shift + Tab.

Variable Refresh Rate Updates

VRR has been refined to take into account a display’s minimum refresh rate. These refinements ensure that the cursor appears to move smoothly, even if an application runs below this minimum refresh rate. The resulting stable cursor framerate is most apparent in non-game applications running in fullscreen mode.

Users Settings

This new settings page lists all user accounts created for the system. When you click on a user, a dropdown reveals options to change the current User’s username and password. Admin Users can change these settings as well, plus toggle Admin permissions for another User.

Open links in Terminal

Links can now be opened from COSMIC Terminal by simply left-clicking on the URL.

ContextDrawer navigation

Header buttons have been added to the ContextDrawer widget. For example, select “Show Details” (or Ctrl+Space) on an image file to open the ContextDrawer. Here, you can use the arrows in the top-left to navigate to the previous or next image, and use the window icon to view the image in a Gallery preview.
