Bazzite Buzz #12


Feral Game Mode has been removed from desktop images. Sorry if this causes any inconveniences. System76 scheduler and Joystickwake completely replace the functionality of it and do not require a launch option to function properly. This feature has always been removed from -deck, -ally, -framegame, and other handheld images, but was mistakenly never removed from the desktop images.

The Nix ujust script has also been removed due to conflicts with SELinux policies. Users can still install the Nix package manager manually if they so desire at their own risk.


Bazzite is a custom image of Fedora Atomic Linux 39 utilizing Universal Blue’s custom image framework designed to bring users the best in Linux gaming for their PCs, including the Steam Deck and other handhelds. Bazzite’s newsletters highlight all of the work we have been doing to bring our users the best features ready to go for their PCs, home theater setups, and handheld gaming devices.

If you are new to the project, then here’s how this technology works. Bazzite and other Universal Blue images follow the continuous delivery methodology of development, which means we’re constantly adding new features and squashing bugs to the image through updates. These updates also include anything directly from upstream (Fedora and Universal Blue) and upgrades from the packages we include. This newsletter is intended to inform current users what has changed since the last Bazzite Buzz which was released over a month ago.

Eight Months of Bazzite

It has been nearly eight months since the first proper public release of Bazzite! Over the last 3 months, there has been a recent spike in popularity and that means we received more feedback on bugs and suggestions for new features more than ever. Universal Blue images have had over 8 million pulls (This includes downloads & updates applied in total) for all of their images including Bazzite. Anyone who has stuck with the project for a while has already seen it evolve and change rapidly. It has really grown into its own identity now.


No longer should curious users search for Bazzite to only find a Github README with bullet points with multiple links. We now have a proper website! There is now an “Image Picker” tool that is intended to guide users on what image they should download based on hardware setup and personal preference of desktop environment as well as the choice of including Game Mode (if supported with your hardware.)

New ISOs Released: A Better Installation Experience

We have new ISOs released with most previous issues that plagued the project now fixed. Each image has its own offline ISO. The new ISOs should install faster and fix issues where the installer would not boot among other issues. Ventoy is now supported with the new ISOs too.

We are confident that the new ISOs are in a much better state than the previous installation method, but as always report bugs with them as you encounter them. We will be adding enhancements and bug fixes to our new ISOs in the coming weeks.

The new ISOs have improved the user experience, but this only phase one of the “new installer.” Fedora’s new WebUI installer will be an even better user experience and allow pre-installed Flatpaks to be installed during installation as opposed to afterwards.

The new ISOs were created using our ISO generator utility.

Handheld Improvements


Several handheld improvements have been made in the past month including working controls for many handhelds, and improved performance. We also fixed scaling and rotation on different hardware, and a ton of other quality of life features. Handhelds from the Lenovo Legion Go and ASUS ROG Ally to different GPD, AYN, and AYANEO hardware should now have proper support.

If you’re looking for an experience similar to SteamOS on a Windows handheld, then you should consider giving Bazzite a try on it. In a matter of fact, we can proudly say that the Lenovo Legion Go is now feature complete!

Here is a showcase of Bazzite on the Lenovo Legion Go:

Unfortunately, the Steam Deck OLED still suffers from audio and refresh rate issues, and since it’s related to the newer kernel versions, we are waiting to see how Valve approaches this when they decide to upgrade SteamOS’s kernel. Eventually the OLED models will have full Steam Deck compatibility like most of the LCD models since these are the last two remaining issues.

For the future, we will also include plans to support the MSI Claw and Orange Pi Neo as more people get their hands on them. We are truly living in the golden age of handheld PCs!

Also check this out! The ASUS ROG Ally running Bazzite with the Apple Vision Pro headset using Moonlight’s iPad port with Sunshine running on the Bazzite host. It’s really incredible to see how creative people can get with these devices.

Message of the Day Added

The terminal now shows a “message of the day” which will randomize tips and helpful information for Bazzite like list what image and update channel you are using, and link to external resources for the project like documentation.

BoxBuddy Pre-Installed for a Graphical Distrobox

We want users to dive in head-first into containers when they need applications that are not available as a Flatpak or as isolated development environments. One of the hurdles of containers for some users is how command-line driven it is, but this GUI can create new Distrobox containers and manage them from a graphical application.


We have added support for ZLUDA, which allows for a drop-in CUDA implementation. This change is not gaming related, but is part of the Bazzite installation if users are interested in this. The directory is present in /usr/lib64/zluda/.

The Phoronix article linked above goes into more detail about this change.

Changes Under The Hood

TuneD Added

TuneD is a service that optimizes battery life and improves performance by using specific profiles for certain workloads. It is an incredibly powerful utility and is best to read the functionality from the official documentation.

The most important takeaway from this is that Bazzite ships with a default profile that should work well on most devices. There is a graphical application that is pre-installed if you plan to make changes of your own. Change TuneD’s settings at your own risk.

Hybrid Graphics Fix

We added this patched switcheroo-control to fix issues with users who have multiple GPUs in their system. Users with specific setups couldn’t launch Steam from the desktop shortcut. This is a known issue upstream, but now it is no longer an issue specifically for Bazzite.

Prompt Rebranded


Due to trademark issues, Prompt had to be renamed, so it is now known as Ptyxis with a different icon.

It still retains the same functionality and goals as it did before the rebrand.

Solving Technical Debt

Both Bazzite and upstream Universal Blue repositories have been cleaned up lately in preparation for the new ISOs that are now released.

ujust has been reorganized with more cleanup and standardization to come with lots of scripts removed or hidden if they caused other issues.

Rescue & Emergency Mode

Rescue & Emergency Mode has been improved significantly. This should give flexibility if your system is having trouble booting your system among other issues. This change also made it upstream too.

New Stable Tag

bazzite:latest is now aliased to bazzite:stable.
:latest is the proper term technically, but :stable makes it clearer that this is the default channel and is intended for daily usage.

Updates Improved

Updates have been reworked using Topgrade which updates nearly everything installed on your system all at once. This is an improvement than how it was setup previously.

There is now an update application that shows an output of everything that is being updated with a verbose log called System Update.

This is useful for forcing updates and seeing everything accurately in real-time especially if you update in Game Mode, where information given to the user is not accurate.



Desktop Images

Desktop images usually auto-update once per day and apply on a reboot, but if you are impatient and want the update now, then open the new System Update tool

Alternatively, open the terminal and enter:

ujust update

Wait for it to finish, then reboot to be on the latest Bazzite build.

Steam Deck/HTPC/Handheld-PC Images

In Game Mode, open the “Settings” > “System” and press the “Check for updates” button.

Alternatively, use the steps above for “Desktop Images” in Desktop Mode.


Atomic Breath


Fedora Magazine wrote an article reintroducing Fedora Immutable as Fedora Atomic, which is an accurate name in comparison to the previous one. The now appropriately named Atomic branding for their OSTree operating systems may give a better first impression than “Immutable” ever did because the OS still allows for flexibility in comparison to other “immutable” systems.

They also gave the Universal Blue project a shout-out too! Thanks!

Eat the Label

All “immutable” Linux operating systems have their own implementation, and some do not allow for the same flexibility that we do. This gives the assumption that the user does not have control over their system and it’s completely locked down.

There are read-only files for stability purposes in Bazzite, but most every-day users should be able to get by without much of a fuss. It’s really only advanced users who may have issues performing tasks like changing the kernel without forking the project. Bazzite is as useful as a daily driver for your desktop computer as it is a “console-like” operating system for handhelds and HTPCs.

Container Ecosystem

While Flatpak is the primary package format for Bazzite, we also made sure that users can have access to universally every Linux package manager and repository with Distrobox and Toolbx. It solves the problem of application support by having access to nearly every application ever made for the Linux desktop ever. Bazzite tries to keep container management as user friendly as it possibly can.

Without deviation from the norm, progress is not possible” - Frank Zappa

Not even our final form

This is only the beginning!

We still need to get the new Fedora installer in the near future which should fix all of the issues left with our installer. Upstream plans to have updates only download new changes in your image rather than download the image all at once again for every upgrade. We want to look for better ways to integrate containers in the system than what we already have.

As always, the goal is to constantly fix issues that are expressed by our users and keep up with the latest Linux gaming trends that should be a Bazzite default. We’re still expanding the project, but the project is nearly feature complete, and it will only be improved upon from now on. The future is looking bright! :sun_with_face:

Branching Paths


Bazzite is one of the two end-user focused images under the Universal Blue family. Originally, the images were intended for users to create their own custom images using a base Fedora image for both personal usage or sharing with the community. This is how Bazzite exists, but Bazzite most likely grew to be the most popular custom based on these statistics.

Now a new way of creating your own custom Fedora Atomic image using the new custom image tooling. BlueBuild project. They are a separate organization from us and have different plans, but many of the images are based on Universal Blue’s old image tools and revamps it by having their own methodology. Read their blog post explaining their goals for the project.

There’s also our incomplete list of custom Fedora Atomic images by the community like Secureblue and Aurora for those who are interested in trying other images that are not Bazzite or Bluefin.
