[Bazzite](https://bazzite.gg/) 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:
- Uses the [fsync kernel](https://copr.fedorainfracloud.org/coprs/sentry/kernel-fsync/) to achieve HDR and expanded hardware support, among numerous other included patches.
- Features optional Valve-inspired GTK3/4 themes matching Vapor and VGUI2 from SteamOS. Install [Gradience](https://flathub.org/apps/com.github.GradienceTeam.Gradience) to make use of them.
- [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
- Uses [TuneD](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/monitoring_and_managing_system_status_and_performance/getting-started-with-tuned_monitoring-and-managing-system-status-and-performance) in place of PPD, with full integration into GNOME, KDE, and Game mode. This is an incredibly powerful tool that RedHat offers [entire classes on](https://www.redhat.com/en/services/training/rh442-red-hat-enterprise-performance-tuning).
- [Ptyxis Terminal](https://gitlab.gnome.org/chergert/ptyxis) used as the default in all images. This terminal is specifically designed for the container workflow you'll use in Bazzite. KDE Konsole and GNOME Console can be installed as flatpaks if required.
- [Input Remapper](https://github.com/sezanzeb/input-remapper) preinstalled and enabled. <sub><sup>(Available but default-disabled on the Deck variant, may be enabled with `ujust restore-input-remapper`)</sup></sub>
- Bazzite Portal provides an easy way to install numerous applications and tweaks, including installing [LACT](https://github.com/ilya-zlobintsev/LACT).
- [Waydroid](https://waydro.id/) preinstalled for running Android apps. Set it up with this [quick guide](https://docs.bazzite.gg/Installing_and_Managing_Software/Waydroid_Setup_Guide/).
- Manage applications using [Flatseal](https://github.com/tchx84/Flatseal), [Warehouse](https://github.com/flattool/warehouse), and [Gear Lever](https://github.com/mijorus/gearlever).
- [OpenRazer](https://openrazer.github.io) drivers built in, Select OpenRazer in Bazzite Portal or run `ujust install-openrazer` in a terminal to begin using it.
- [OpenTabletDriver](https://opentabletdriver.net/) udev rules built in, with the full software suite installable via Bazzite Portal or by running `ujust install-opentabletdriver` in a terminal.
- 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.
- [Webapp Manager](https://github.com/linuxmint/webapp-manager) is available for creating applications from websites for a variety of browsers, including Firefox.
- Automatic updates for the OS, Flatpaks, and all Distrobox containers - powered by [ublue-update](https://github.com/ublue-os/ublue-update) and [topgrade](https://github.com/topgrade-rs/topgrade).
> **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/).**
(Please note: Mesa's Open Source option for NVIDIA GPUs, NVK is still prone to errors at the time of writing, for any issues relating to NVK [please submit a report with Mesa]([url](https://docs.mesa3d.org/bugs.html)), not Ublue/Bazzite)
Devices that are NOT the Steam Deck can still use the `bazzite-deck` images, but must use a modern AMD GPU. Intel Arc GPUs also have been confirmed to work.
- 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, and Distrobox images to be updated directly from the Game mode UI powered by [ublue-update](https://github.com/ublue-os/ublue-update) and [topgrade](https://github.com/topgrade-rs/topgrade).
- 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 Game mode and on the Desktop if Discord is installed. [View the official documentation here](https://trigg.github.io/Discover/bazzite).
- Uses ZRAM<sub><sup>(4GB)</sup></sub> with the ZSTD compression algorithm by default with the option to switch back to a 1GB swap file and set a custom size for it if desired.
- Service for low-risk undervolting of the Steam Deck as well as AMD Framework Laptops 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 `CUSTOM_REFRESH_RATES=30-68` to `/etc/environment`. Minimum and maximum refresh rates differ per handheld!
- 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 `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.
> **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/).**
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.
**Be sure to also read the [hhd documentation](https://github.com/hhd-dev/hhd#after-install), some handhelds require specific setting changes/tweaks to function properly.**
We also ship `ujust` commands to install various [CSS Loader](https://docs.deckthemes.com/CSSLoader/Install/#linux-or-steam-deck) themes that can't be found on the CSS Loader store. These will be automatically updated with Bazzite if installed.
- 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 `ujust enroll-secure-boot-key` and enter the password `universalblue` 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 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).

- [ChimeraOS](https://chimeraos.org/) - For gamescope-session and for valuable support along the way.
- [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.
- [sentry](https://copr.fedorainfracloud.org/coprs/sentry/) - For assistance with needed kernel patches and for creating the [kernel-fsync repo](https://copr.fedorainfracloud.org/coprs/sentry/kernel-fsync/) we now use.
- [nicknamenamenick](https://github.com/nicknamenamenick) - For being the MVP nearly single-handedly upkeeping our documentation and support literature, and countless cases of helping users.
- [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.
- [cyrv6737](https://github.com/cyrv6737) - For the initial inspiration and the base that became bazzite-arch.
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.
