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

or for devices with Nvidia GPUs wanting the NVIDIA Proprietary Drivers:

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

For users with Secure Boot enabled: Follow our secure boot documentation prior to rebasing.

Steam Deck/Home Theater PCs (HTPCs)

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:

  • 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-bios-updates and ujust disable-firmware-updates in the terminal. These are automatically disabled on non-Deck hardware, and on Decks with DeckHD displays or 32GB RAM mods.
• More information can be found here on the Bazzite Steam Deck images.

Features from Upstream

Universal Blue

• Proprietary Nvidia drivers pre-installed. _{^{(Only for Nvidia images)}}
• Flathub is enabled by default.
• ujust commands for convenience.
• Multi-media codecs out of the box.
• Rollback Bazzite from any build within the last 90 days.

Features from Fedora Linux (Kinoite & Silverblue)

• A rock solid and stable base.
• System packages stay relatively up to date.
• Can layer Fedora packages to the image without losing them between updates.
• Security focused with SELinux preinstalled and configured out of the box.
• The ability to rebase to different Fedora Atomic images, if desired, without losing user data.
• Printing support thanks to CUPS being preinstalled.

Why

Bazzite started as a project to resolve some of the issues that plague SteamOS, mainly out of date packages (despite an Arch base) and the lack of a functional package manager.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 universalblue if prompted to enroll our key)}} and disk encryption, making this a sensible solution for general computing. _{^{(Yes, you can print from Bazzite)}}

Verification

These images are signed with sigstore's cosign. You can verify the signature by downloading the cosign.pub key from this repo and running the following command:

cosign verify --key cosign.pub ghcr.io/ublue-os/bazzite

Secure Boot

[!WARNING] Steam Deck Users: The Steam Deck does not come with secure boot enabled and does not ship with any keys enrolled by default. Do not enable this unless you absolutely know what you're doing.

Secure boot is supported with our custom key. The pub key can be found in the root of this repository here. If you'd like to enroll this key prior to installation or rebase, download the key and run the following:

sudo mokutil --timeout -1
sudo mokutil --import secure_boot.der

For users already on a Universal Blue image, you may instead run ujust enroll-secure-boot-key.

If asked for a password, use universalblue.

Star History

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:

• amelia.svg - For creating our logo and overall branding.
• SuperRiderTH - For creating our Steam game mode startup video.
• 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.
• sentry - For assistance with needed kernel patches and for creating the kernel-fsync repo.
• nicknamenamenick - For being the MVP nearly single-handedly upkeeping our documentation and support literature, and countless cases of helping users.
• 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 via GitHub Actions. Creating your own custom version of it is as easy as forking this repository, adding a private signing key, and enabling the fork's GitHub Actions. Running the Build Bazzite workflow will then generate custom images for all variants of Bazzite.

If you only want to generate images for the variants of Bazzite you are using, edit .github/workflows/build.yml to comment out the variants you do not wish to build in the push-ghcr job's strategy's matrix list.

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.

How to Sign Your Images

1. First, familiarize yourself with keeping secrets on GitHub.
2. Generate a new key pair with Cosign (cosign generate-key-pair). This key pair must have no signature.
3. Replace the cosign.pub file in your public repo with the one you generated - you and your users will need it to check the signatures.
4. Add the private key (stored as text inside the cosign.key file) as a Repository Secret in the fork's settings page, in the Settings -> Secrets and variables -> Actions menu. Name the secret SIGNING_SECRET.
