CachyOS on handheld PCs: current setup, bootloader notes and alternatives

Checked October 8, 2026. CachyOS Handheld Edition is an Arch-based Linux system for devices such as Steam Deck, ROG Ally and Lenovo Legion Go. It aims to provide a controller-friendly Game Mode while retaining a rolling-release desktop and current packages. That flexibility also means more frequent changes than a console-style fixed system.  ## What it includes The [Handheld Edition documentation](https://wiki.cachyos.org/installation/installation_handheld/) describes Game Mode Switching, preinstalled gaming apps, KDE Plasma, the LAVD CPU scheduler, Limine with automatic snapshots, and systemd-boot as an alternative. Those are project design choices, not guarantees of better frame rates or battery life: results depend on the handheld, game, power profile, drivers and version. One detail deserves a double-check: the separate [CachyOS-Handheld GitHub README](https://github.com/CachyOS/CachyOS-Handheld) still describes systemd-boot as the default, while the current wiki describes Limine and snapshots. Check the release notes and the installer’s actual bootloader choices for the ISO you download, especially if you plan to dual-boot. ## Install carefully 1. **Download the latest Handheld ISO** from the official [CachyOS download page](https://cachyos.org/download/) and follow the [USB preparation and verification steps](https://wiki.cachyos.org/installation/installation_prepare/). Verify the published checksum or signature before installation. 2. **Back up the internal drive.** The current root-install guide recommends “Erase Disk.” That removes the existing system and data. Do not choose it unless you intend to wipe the drive. 3. **For dual-boot, use the manual partition guide.** CachyOS warns that replacing another distribution’s partition may not work as expected. Do not assume an existing Windows/Linux layout is compatible; confirm the bootloader and partition plan before writing changes. 4. **After installation, test the basics:** Wi-Fi, audio, controls, screen orientation, sleep and wake, TDP controls, external display and the games you play. Keep a separate backup even when snapshots are enabled. Snapshots can help recover from some bad system updates, but they are not a backup against drive failure or accidental deletion of personal files. Arch-based rolling updates also reward users who read update notes and are comfortable troubleshooting. If a major update is mission-critical, wait for the project’s current guidance and make sure you have a recovery plan before installing it. ## What a handheld test can—and cannot—tell you A review on one model is useful for seeing the interface and setup, but it cannot settle compatibility for all handhelds. Input controls, sleep behavior, audio, fingerprint readers, firmware tools and TDP controls vary by hardware. When reporting a problem, include the device model, ISO date, bootloader, firmware and the specific feature that failed. For performance claims, compare the same game and settings at the same power limit. ## How it compares - **CachyOS Handheld:** handheld-focused tools and a rolling Arch base for users who want control and can maintain it. - **SteamOS:** Valve’s most integrated Steam Deck experience; support on other hardware is model-specific. - **Bazzite:** a Fedora Atomic gaming image with Steam Gaming Mode, device guides and system rollback. - **Anatase:** an immutable image with HHD controls and Spaces, but a newer and faster-moving project. No distribution is universally fastest. Compare the same game at the same resolution, settings and power limit, and check Linux anti-cheat support for multiplayer games before switching. ## Creator walkthrough: CachyOS on MSI Claw [PickleFlickPF’s CachyOS test on the MSI Claw A1M](https://youtu.be/Ki62OuXCYhw) shows the install, handheld adjustments and game testing on that specific device. The creator’s notes describe a few manual changes to the handheld setup and mixed compatibility results. Treat it as an individual field test, not a benchmark or a promise that the same configuration will work on a Steam Deck, Ally or Legion Go. ## Official references - [CachyOS Handheld Edition install guide](https://wiki.cachyos.org/installation/installation_handheld/) - [CachyOS downloads and ISO verification](https://cachyos.org/download/) - [USB preparation guide](https://wiki.cachyos.org/installation/installation_prepare/) - [Handheld Edition source and README](https://github.com/CachyOS/CachyOS-Handheld) - [Bazzite handheld guide](https://docs.bazzite.gg/Handheld_and_HTPC_edition/Handheld_Wiki/) - [Valve SteamOS](https://store.steampowered.com/steamos/) - [Anatase](https://anatase.org/) If you have installed it, share the handheld model, ISO date, bootloader choice and any issues.
