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:
- [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>
- Helpful first-start installer 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).
- [Waydroid](https://waydro.id/) preinstalled for running Android apps. Future releases will offer to set this up for you. <sub><sup>(Not available on Nvidia builds)</sup></sub>
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://github.com/ublue-os/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).
- Comes with patches from [SteamOS BTRFS](https://gitlab.com/popsulfr/steamos-btrfs) for full BTRFS support for the SD card by default.
- Ships with a ported copy of [SDGyroDSU](https://github.com/kmicki/SteamDeckGyroDSU), enabled by default.
- Option to install [Decky Loader](https://github.com/SteamDeckHomebrew/decky-loader), [EmuDeck](https://www.emudeck.com/), and [ProtonUp-Qt](https://davidotek.github.io/protonup-qt/), among numerous other useful packages on installation.
- Custom update system allows for the OS, Flatpaks, and Distrobox images to be updated directly from the Gamemode UI.
- Built in support for 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.
- 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), 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>
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>
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 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:

- [Jovian-NixOS](https://github.com/Jovian-Experiments) - 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](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.
[Read the docs](https://docs.github.com/en/actions/security-guides/encrypted-secrets) on keeping secrets in github. You need to [generate a new keypair](https://docs.sigstore.dev/cosign/overview/) 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.
We also ship a config for the popular [pull bot](https://github.com/wei/pull) if you'd like to keep your fork in sync with upstream. Simply enable this bot on your repo.
