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>
**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>
- 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/).
