Bazzite OS on ROG Ally: How to Install and Why Battery Life Doubles

Bazzite is a Linux distribution built specifically for gaming handhelds. It brings a SteamOS-like experience to the ROG Ally, ROG Ally X, and other Windows-based handhelds that Valve does not officially support. Installing it transforms a Windows handheld into something that behaves like a Steam Deck.

What Is Bazzite?

Bazzite is based on Fedora Linux with a gaming-optimized layer on top. For the ROG Ally and Ally X, it provides:

• A Steam Deck-style Gaming Mode interface that boots directly to a game launcher
• Optimized ROG Ally drivers for the display, controls, and power management
• Better battery life than Windows through more efficient resource management
• Access to the full Steam library via Proton
• Desktop Mode (KDE Plasma) for when you need a full desktop environment

Bazzite is free and maintained by a large open-source community. As of 2026, ROG Ally driver support in Bazzite is mature enough that most functions work correctly out of the box.

Bazzite vs Windows on ROG Ally X: Key Differences

How to Install Bazzite on ROG Ally X

The installation process takes 30 to 60 minutes and requires a USB drive of at least 8GB.

1. Download the Bazzite ISO for ROG Ally from bazzite.gg (choose the ROG Ally / Handheld variant)
2. Flash it to a USB drive using Rufus (Windows) or Balena Etcher
3. Boot the ROG Ally X from the USB drive (hold Volume Down and press Power to enter boot menu)
4. Run the Bazzite installer, it walks through partitioning and setup
5. After installation, the system reboots into Bazzite’s Gaming Mode

Bazzite can be installed alongside Windows (dual-boot) or as a full replacement. Dual-boot is recommended for new users so you can return to Windows if needed. The installer handles dual-boot setup automatically if Windows is already on the device.

Performance After Installing Bazzite

Battery life improves noticeably on Bazzite compared to Windows on the ROG Ally X. Windows background processes, the Armoury Crate software, and anti-virus scanning all consume power that Bazzite does not. In light-to-medium games, expect 1 to 2 additional hours per charge.

Game performance is comparable to Windows for most Steam titles. Proton handles the vast majority of the Steam catalog. For games with aggressive anti-cheat (some online shooters), Windows remains the safer choice.

Before You Install: BIOS Settings, USB Size, and Picking the Right Image

A few details trip people up before the installer even runs. Get these right first.

• Disable Secure Boot first. Enter the ROG Ally’s BIOS (hold Volume Down and press Power, same combo as the boot menu, then look for the BIOS/UEFI option) and turn off Secure Boot. The installer won’t boot from USB with it enabled.
• Use a 16GB+ USB drive, not the minimum 8GB. The ISO itself sits close to that size, and a tight-fitting drive causes flashing tools to fail partway through. A 32GB drive removes any doubt.
• Pick the handheld-specific image, not the generic desktop build. Bazzite’s download page separates a handheld/Deck-style image from the standard GNOME/KDE desktop image. The handheld image ships with ROG Ally driver support and the Gaming Mode interface built in, the desktop image will boot but won’t have working power management or the console-style UI.
• Update the ROG Ally’s own BIOS/firmware in Armoury Crate before you leave Windows. Doing this after wiping Windows means booting back into Windows just for a firmware update, which defeats the point of a clean switch.

Keeping Bazzite Updated After Install

Bazzite updates itself as a full system image using rpm-ostree, the same underlying approach SteamOS uses. Updates show up under Settings, System, Software Update in Gaming Mode, and applying one requires a reboot to switch to the new image. Check every week or two, ROG Ally hardware support (Wi-Fi, controller behavior, display scaling) tends to improve with nearly every release in the first year after a new handheld gets Bazzite support.

Common Issues After Installing

• Wi-Fi drops after the device wakes from sleep. This is a known rough edge on some kernel versions. Check for a pending system update first, it’s usually resolved within a release or two of first appearing.
• Refresh rate doesn’t switch automatically between games. Set it manually from the Quick Settings panel until you find a per-game rate that sticks.
• Controller rumble feels inconsistent between games. This is a Steam Input mapping issue, not a hardware fault. Open the per-game controller settings and check the rumble intensity slider, some Proton titles default it low.
• Want to go back to Windows. If you dual-booted, use Windows Disk Management from a Windows recovery USB to delete the Bazzite partition and extend the Windows partition back into that space. If you did a full replacement, download the ROG Ally recovery image from Asus’s support site and reflash from USB the same way you installed Bazzite.

Should You Install Bazzite on Your ROG Ally X?

Install Bazzite if you primarily play Steam games and want a better handheld interface and longer battery life. The SteamOS-like Gaming Mode is genuinely more pleasant to use than Windows for handheld gaming.

Stick with Windows if you rely on Xbox Game Pass local downloads, play games with aggressive anti-cheat, or need the ROG Ally X to function as a Windows PC for work tasks.

For official SteamOS on a non-Valve device, the Lenovo Legion Go 2 now ships with SteamOS pre-installed. See our Legion Go 2 SteamOS guide for details. For a full comparison of the ROG Ally X and Steam Deck at current prices, see our ROG Ally X vs Steam Deck OLED comparison.
