Bazzite is an OCI image that serves as an alternative operating system for the [Steam Deck](https://www.steamdeck.com/), and a ready-to-game SteamOS-like for desktop computers and living room home theater PCs.
Bazzite is built from [ublue-os/main](https://github.com/ublue-os/main) and [ublue-os/nvidia](https://github.com/ublue-os/nvidia) using [Fedora](https://fedoraproject.org/) technology, which means expanded hardware support and built in drivers are included. Additionally, Bazzite adds the following features:
- [xone](https://github.com/medusalix/xone), [xpadneo](https://github.com/atar-axis/xpadneo), and [xpad-noone](https://github.com/ublue-os/xpad-noone) drivers for Xbox controllers.
- [LatencyFleX](https://github.com/ishitatsuyuki/LatencyFleX), [vkBasalt](https://github.com/DadSchoorse/vkBasalt), [MangoHud](https://github.com/flightlessmango/Mangohud), and [OBS VkCapture](https://github.com/nowrep/obs-vkcapture) installed and available by default
- [System76-Scheduler](https://github.com/pop-os/system76-scheduler) preinstalled, providing automatic process priority tweaks to your focused application and keeping CPU time for background processes to a minimum.
- Customized System76-Scheduler config with additional rules and CFS parameters from [Linux-TKG](https://github.com/Frogging-Family/linux-tkg).
- [Input Remapper](https://github.com/sezanzeb/input-remapper) preinstalled and enabled. <sub><sup>(Available but default-disabled on the Deck variant)</sup></sub>
- Bazzite Portal provides an easy way to install numerous applications and tweaks, including installing [CoreCtrl](https://gitlab.com/corectrl/corectrl) and [GreenWithEnvy](https://gitlab.com/leinardi/gwe).
- [Nix](https://nixos.org/) package manager and [Fleek](https://getfleek.dev/) optionally available for install via Bazzite Portal.
- [Waydroid](https://waydro.id/) preinstalled for running Android apps. Future releases will offer to set this up for you through Bazzite Portal. <sub><sup>(Not available on Nvidia builds)</sup></sub>
- [OpenRazer](https://openrazer.github.io) drivers built in, Select OpenRazer in Bazzite Portal or run `just install-openrazer` in a terminal to begin using it.
- Built in support for Southern Islands <sub><sup>(HD 7000)</sup></sub> and Sea Islands <sub><sup>(HD 8000)</sup></sub> AMD GPUs under the `amdgpu` driver.
- A fix is available for [a TF2 bug](https://github.com/ValveSoftware/Source-1-Games/issues/5043) that makes the game crash on launch - `just fix-tf2-tcmalloc`

If you're on an existing Universal Blue image follow [these instructions](https://universal-blue.org/images/#image-list). To rebase an existing upstream Fedora Silverblue/Kinoite ostree system to this image:
**For users with Secure Boot enabled:** Once you've installed or rebased to a Nvidia build, [be sure to follow step 3 from the ublue-os/nvidia guide](https://universal-blue.org/images/nvidia/#3-enable-secure-boot-support).
- Features ported versions of most SteamOS packages, including drivers, firmware updaters, and fan controllers [from the evlaV repository](https://gitlab.com/evlaV).
- Option to install [Decky Loader](https://github.com/SteamDeckHomebrew/decky-loader), [EmuDeck](https://www.emudeck.com/), [RetroDECK](https://retrodeck.net/), and [ProtonUp-Qt](https://davidotek.github.io/protonup-qt/), among numerous other useful packages on installation.
- Custom update system allows for the OS, Flatpaks, Nix packages <sup><sub>(Via Fleek)</sub></sup>, and Distrobox images to be updated directly from the Gamemode UI.
- 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.
- [Discover Overlay](https://github.com/trigg/Discover) for Discord pre-installed and automatically launches in both Gamemode and on the Desktop if Discord is installed and feature is enabled. See `/etc/default/discover-overlay` to enable automatic launching.
- Exclusively uses ZRAM by default with the option to switch back to a swap file and set a custom size if desired. <sub><sup>(1GB by default)</sup></sub>
- Service for low-risk undervolting of the Steam Deck via [RyzenAdj](https://github.com/FlyGoat/RyzenAdj) and [Ryzen SMU](https://gitlab.com/leogx9r/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`. <sup><sub>(Works even when the device is off)</sub></sup>
- Built in support for display overclocking. For example, add `GAMESCOPE_OVERRIDE_REFRESH_RATE=40,70` to `/etc/environment`.
- 32GB RAM mod your Steam Deck? Enjoy double the maximum VRAM amount, automatically applied. <sup><sub>(Can you share your soldering skills?)</sub></sup>
- Steam Deck hardware-specific services can be disabled by running `just disable-deck-services` in the terminal, useful for trying this image on other handhelds or for use on HTPCs.

If you're on an existing Universal Blue image follow [these instructions](https://universal-blue.org/images/#image-list). To rebase an existing upstream Fedora Silverblue/Kinoite ostree system to this image:
- Custom menu in the top bar for returning to game mode, launching Steam, and opening a number of useful utilities. <sub><sup>(Only on Steam Deck builds)</sup></sub>
- 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). <sup><sub>(If installed)</sub></sup>

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 <sub><sup>(So go ahead and install that obscure VPN software you spent an hour trying to get working in SteamOS)</sup></sub>. 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 <sub><sup>(Run `just enroll-secure-boot-keys` and enter the password `ublue-os` if prompted to enroll our key)</sup></sub> and disk encryption, making this a sensible solution for general computing. <sup><sub>(Yes, you can print from Bazzite)</sub></sup>
Ported SteamOS and ChimeraOS packages, among others used by Bazzite, are built on Copr in [bazzite](https://copr.fedorainfracloud.org/coprs/kylegospo/bazzite/) and [bazzite-multilib](https://copr.fedorainfracloud.org/coprs/kylegospo/bazzite-multilib/).
These images are signed with sigstore's [cosign](https://docs.sigstore.dev/cosign/overview/). You can verify the signature by downloading the `cosign.pub` key from this repo and running the following command:

- [Steam Deck Homebrew](https://deckbrew.xyz) - For choosing to support distributions other than SteamOS despite the extra work, and a special thanks to [PartyWumpus](https://github.com/PartyWumpus) for getting Decky Loader working with SELinux for us.

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](https://docs.github.com/en/actions/security-guides/encrypted-secrets) on keeping secrets in github. You'll need to [generate a new keypair](https://docs.sigstore.dev/cosign/overview/) with cosign. The public key can be in your public repo <sub><sup>(Your users need it to check the signatures)</sup></sub>, 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](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.
