ISOs can be downloaded from our releases page here, and a helpful install guide can be found here.

If you're on an existing Universal Blue image follow these instructions. To rebase an existing upstream Fedora Silverblue/Kinoite ostree system to this image:

rpm-ostree rebase

or for devices with Nvidia GPUs:

rpm-ostree rebase

For users with Secure Boot enabled: Run ujust enroll-secure-boot-key and enter the password ublue-os if prompted to enroll the required key.

Steam Deck/Home Theater PCs (HTPCs)

Devices that are NOT the Steam Deck can still use the bazzite-deck images, but must use an AMD/Intel GPU.

Variant designed for usage as an alternative to SteamOS on the Steam Deck, and for a console-like experience on HTPCs, available as bazzite-deck:

  • Directly boots to Gamemode matching SteamOS's behavior.
  • Automatic duperemove greatly trims the size of compatdata.
  • Latest version of Mesa creates smaller shader caches and does not require them to prevent stutter.
  • Able to be booted even if the drive is full.
  • Support for every language supported by upstream Fedora.
  • Optionally use Wayland on the desktop with support for Steam input.
  • Features ported versions of most SteamOS packages, including drivers, firmware updaters, and fan controllers from the evlaV repository.
  • Patched Mesa for proper framerate control from Gamescope.
  • Comes with patches from SteamOS BTRFS for full BTRFS support for the SD card by default.
  • Ships with a ported copy of SDGyroDSU, enabled by default.
  • Option to install Decky Loader, EmuDeck, RetroDECK, and ProtonUp-Qt, among numerous other useful packages on installation.
  • Custom update system allows for the OS, Flatpaks, Nix packages (Via Fleek), and Distrobox images to be updated directly from the Gamemode UI.
  • Built in support for Windows dual-boot thanks to Fedora's installation of GRUB being left intact.
  • Update break something? Easily roll back to the previous version of Bazzite thanks to rpm-ostree's rollback functionality. You can even select previous images at boot.
  • Steam and Lutris preinstalled on the image as layered packages.
  • Discover Overlay for Discord pre-installed and automatically launches in both Gamemode and on the Desktop if Discord is installed. View the official documentation here.
  • Uses ZRAM(4GB) with the ZSTD compression algorithm by default with the option to switch back to a 1GB swap file and set a custom size for it if desired.
  • Kyber I/O scheduler to prevent I/O starvation when installing games or during background duperemove and rmlint processes.
  • Applies SteamOS's kernel parameters.
  • Color calibrated display profiles for matte and reflective Steam Deck screens included.
  • Default-disabled power-user features, including:
    • Service for low-risk undervolting of the Steam Deck via RyzenAdj and Ryzen SMU, see ryzenadj.service and /etc/default/ryzenadj.
    • Service for limiting the max charge level of the battery, see batterylimit.service and /etc/default/batterylimit. (Works even when the device is off)
    • Built in support for display overclocking. For example, add GAMESCOPE_OVERRIDE_REFRESH_RATE=40,70 to /etc/environment.
    • Ability to enable Wayland on the desktop if desired by editing /etc/default/desktop-wayland.
    • 32GB RAM mod your Steam Deck? Enjoy double the maximum VRAM amount, automatically applied. (Can you share your soldering skills?)
  • Steam Deck hardware-specific services can be disabled by running ujust disable-deck-services in the terminal, useful for trying this image on other handhelds or for use on HTPCs.

Due to an upstream bug, Bazzite cannot be used on Steam Decks with 64GB eMMC storage at this time. Upgrading the storage resolves the issue.

ISOs can be downloaded from our releases page here, and a helpful install guide can be found here.

Builds with the GNOME desktop environment are available in both desktop and deck flavors. These builds come with the following additional features:

Bazzite started as a project to resolve some of the issues that plague SteamOS, mainly out of date packages (despite an Arch base) and the lack of a functional package manager.

Despite this project also being image-based, you are able to install any Fedora package straight from the command line. These packages will persist across updates (So go ahead and install that obscure VPN software you spent an hour trying to get working in SteamOS). Additionally, Bazzite is updated multiple times a week with packages from upstream Fedora, giving you the best possible performance and latest features - all on a stable base.

Bazzite ships with the latest Linux kernel and SELinux enabled by default with full support for secure boot (Run ujust enroll-secure-boot-key and enter the password ublue-os if prompted to enroll our key) and disk encryption, making this a sensible solution for general computing. (Yes, you can print from Bazzite)

Special Thanks

Bazzite is a community effort and wouldn't exist without everyone's support. Below are some of the people who've helped us along the way:

  • rei0260 - For creating our logo and overall branding.
  • evlaV - For making Valve's code available and for being this person.
  • ChimeraOS - For gamescope-session and for valuable support along the way.
  • Jovian-NixOS - For supporting us with technical issues and for creating a similar project. Seriously, go check it out. It's our Nix-based cousin.
  • Steam Deck Homebrew - For choosing to support distributions other than SteamOS despite the extra work, and a special thanks to PartyWumpus for getting Decky Loader working with SELinux for us.
  • cyrv6737 - For the initial inspiration and the base that became bazzite-arch.

Build Your Own

Bazzite is built entirely in GitHub and creating your own custom version of it is as easy as forking this repository, adding a private signing key, and enabling GitHub actions.

Familiarize yourself on keeping secrets in github. You'll need to generate a new keypair with cosign. The public key can be in your public repo (Your users need it to check the signatures), and you can paste the private key in Settings -> Secrets -> Actions with the name SIGNING_SECRET.

We also ship a config for the popular pull app if you'd like to keep your fork in sync with upstream. Enable this app on your repo to keep track of Bazzite changes while also making your own modifications.
