What is it?

Bazzite is a custom operating system image built on Fedora Atomic (Kinoite and Silverblue) and assembled with Universal Blue tooling. It targets Linux gaming on desktop PCs, Steam Deck, other handhelds and home theater PCs, with HDR and VRR support, Xbox controller drivers, and MangoHud, vkBasalt and OBS VkCapture installed by default.

The Steam Deck and HTPC variant boots directly into Game mode with behavior matching SteamOS, and includes ported SteamOS packages, Decky Loader and EmuDeck options, and sched-ext scheduler support. Desktop variants ship with Flathub enabled, Distrobox, Waydroid for Android apps, and a GNOME edition with GSConnect preinstalled.

Because it is an image-based system, updates and rollbacks are handled at the image level, and Fedora packages can be layered on top and persist across updates. Images are built with GitHub Actions and can be forked and customized.

Key features

  • 01Preinstalled gaming tools including MangoHud, vkBasalt, and OBS VkCapture
  • 02Steam Deck variant boots directly into a SteamOS-like Game mode
  • 03Automatic updates for the OS and Flatpaks, with rollback to recent builds
  • 04Layer Fedora packages that persist across image updates
  • 05SELinux enabled by default with Secure Boot support

Use cases

  • Running a Linux desktop focused on Steam and gaming
  • Replacing SteamOS on a Steam Deck or other handheld
  • Setting up a home theater PC with a console-like interface
  • Trying a stable, image-based Fedora desktop with easy rollbacks

Quick start

  1. 1

    Download the ISO from the official website and follow the install guide

  2. 2

    If you already run upstream Fedora Atomic, rebase to the desktop image

    rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/bazzite:stable
  3. 3

    For NVIDIA GPUs wanting proprietary drivers, rebase to the NVIDIA image instead

    rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/bazzite-nvidia:stable

Things to know

  • Rebasing requires an existing Fedora Atomic installation, so it is not a plain app install.
  • The open-source NVIDIA driver option (NVK) is still prone to errors according to the README.
  • Users with Secure Boot enabled must follow extra documentation before rebasing.
