This readme will cover everything in-depth. [Bazzite](https://bazzite.gg/) is a custom [Fedora Atomic](https://fedoraproject.org/atomic-desktops/) image built with [cloud native](https://universal-blue.org/#cloud-native) technology that brings the best of Linux gaming to **all of your devices - including your favorite handheld**. Bazzite is built from [ublue-os/main](https://github.com/ublue-os/main) using [Fedora](https://fedoraproject.org/) technology, which means expanded hardware support and built in drivers are included.

These are automatically disabled on non-Deck hardware, and on Decks with DeckHD displays or 32GB RAM mods. - More information can be found [here](https://docs.bazzite.gg/Handheld_and_HTPC_edition/Steam_Gaming_Mode/) on the Bazzite Steam Deck images. > [!IMPORTANT] > **ISOs can be downloaded from our [website](https://download.bazzite.gg), and a helpful install guide can be found [here](https://docs.bazzite.gg/General/Installation_Guide/).** Rebase from an existing upstream Fedora Atomic to this image: ```bash rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/bazzite-deck:stable ``` #### Alternative Handhelds Please refer to our [Handheld Wiki](https://docs.bazzite.gg/Handheld_and_HTPC_edition/Handheld_Wiki/) for required setting changes and Decky Loader plugins for Steam Gaming Mode on your specific Handheld. ### GNOME Builds with the GNOME desktop environment are available in both desktop and deck flavors. These builds come with the following additional features: - [Variable refresh rate support and fractional scaling enabled under Wayland](https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1154). - Custom menu in the top bar for returning to game mode, launching Steam, and opening a number of useful utilities. - [GSConnect](https://extensions.gnome.org/extension/1319/gsconnect/) preinstalled and ready to use. - [Hanabi extension](https://github.com/jeffshee/gnome-ext-hanabi) included to offer similar features to Wallpaper Engine in KDE. - Numerous optional extensions pre-installed, including [important user experience fixes](https://www.youtube.com/watch?v=nbCg9_YgKgM). - Automatic updates for the [Firefox GNOME theme](https://github.com/rafaelmardojai/firefox-gnome-theme) and [Thunderbird GNOME theme](https://github.com/rafaelmardojai/thunderbird-gnome-theme). _{^{(If installed)}} > [!IMPORTANT] > **ISOs can be downloaded from our [website](https://download.bazzite.gg), and a helpful install guide can be found [here](https://docs.bazzite.gg/General/Installation_Guide/).** Rebase from an existing upstream Fedora Atomic to this image: ```bash rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/bazzite-gnome:stable ``` To rebase an existing ostree system to a Desktop Environment with the **Proprietary NVIDIA Drivers** release: ```bash rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/bazzite-gnome-nvidia:stable ``` To rebase an existing ostree system to the **Steam Deck/HTPC** release: ```bash rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/bazzite-deck-gnome:stable ``` **For users with Secure Boot enabled:** Follow our [secure boot documentation](#secure-boot) prior to rebasing. ### Features from Upstream #### Universal Blue - Proprietary Nvidia drivers pre-installed. _{^{(Only for Nvidia images)}} - Flathub is enabled by default. - [`ujust`](https://github.com/casey/just) 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](https://github.com/SELinuxProject/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](https://www.cups.org/) 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)}} Read the [FAQ](https://docs.bazzite.gg/General/FAQ/) for details on what makes Bazzite stand out from other Linux based operating systems. ## Showcase        ## Documentation - [Installing and Managing Applications](https://docs.bazzite.gg/Installing_and_Managing_Software/) - [Updates, Rollbacks, and Rebasing](https://docs.bazzite.gg/Installing_and_Managing_Software/Updates_Rollbacks_and_Rebasing/) - [Gaming Guide](https://docs.bazzite.gg/Gaming/) View [additional documentation](http://docs.bazzite.gg/) surrounding the project. ## Verification These images are signed with sigstore's [cosign](https://docs.sigstore.dev/cosign/key_management/overview/). You can verify the signature by downloading the `cosign.pub` key from this repo and running the following command: ```bash 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](https://github.com/ublue-os/bazzite/blob/main/secure_boot.der). If you'd like to enroll this key prior to installation or rebase, download the key and run the following: ```bash 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`. ## Contributor Metrics  ## Star History ## Special Thanks Bazzite is a community effort and wouldn't exist without everyone's support.

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](https://github.com/apps/pull) 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](https://docs.github.com/en/actions/security-guides/encrypted-secrets) with keeping secrets on GitHub. 2. [Generate a new key pair](https://docs.sigstore.dev/cosign/key_management/signing_with_self-managed_keys/) 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`. ## Join The Community You can find us on the [Bazzite Discord](https://discord.gg/f8MUghG5PB) View the [archive](https://www.answeroverflow.com/c/1072614816579063828/1143023993041993769) of support threads without an account.
