I Turned Fedora 43 Into A Steam Deck - Gamescope Launcher For Fedora

People asked for it, so here it is. A Gamescope Steam Deck mode launcher for Fedora. Same concept as the Omarchy, CachyOS, Pop, and Mint versions — press a keybind, your desktop shuts down, Gamescope takes over, and you're in a pure Steam Deck gaming session. Press another keybind, you're back on your desktop. No command lines, no launch options, just games.
This one is built for Fedora 43 Workstation running GNOME on Nvidia. I walk through the entire process from a fresh install — getting the Nvidia drivers sorted, installing the launcher, and playing a game in Gamescope.

NVIDIA DRIVERS ON FEDORA
Fedora and Nvidia have a complicated history. Previous versions had a nightmare scenario where you'd install drivers, run an update, and get a black screen. Fedora 43 is much better. I use Claude Code to quickly identify what needs doing — it detects the 5060 Ti, spots the nouveau drivers, and gives me the exact commands to enable the RPM Fusion repo and install the akmod Nvidia drivers. One reboot and the Nvidia X Server app appears. Nearly painless.
If you're new to Fedora and coming from something like Mint where driver installation is a checkbox, this is a slightly different process but it's straightforward once you know the steps.

THE INSTALL
The Gamescope launcher script handles everything else. It pulls down dependencies, builds Gamescope from source, installs MangoHUD, sets up the ChimeraOS session switching backend, bootstraps Steam, and installs ProtonGE. There's a compilation step for Gamescope that takes a bit of time depending on your CPU — on the Ryzen 9 it's quick but slower machines will need patience.

Once it's done, reboot, and Super+Shift+G launches you into Steam Deck mode. Set up your resolution, disable HDR if your monitor doesn't support it, switch on MangoHUD overlays, disable the frame rate limit, and you're gaming.

COMING BACK TO THE DESKTOP
One small difference with the Fedora version compared to Omarchy — when you exit Gamescope with Super+Shift+R, you come back to a login screen rather than dropping straight back to your desktop session. You just log back in and you're where you were. It's one extra step but it works cleanly. Getting passwordless session restoration working on GNOME was causing too many issues so this was the more reliable approach.

ARC RAIDERS FIRST LAUNCH QUIRK
I demo with Arc Raiders which has a known behaviour on every distro I've tested — the first launch in a fresh Gamescope session connects to the server, loads partially, then drops out. Launch it a second time and it's solid. I think it's a server connection issue rather than anything platform-specific. Other games load straight in without problems.

EXTERNAL GAME DRIVES
Same as every other version of the launcher — if you've got an external drive with a Steam library on it, the script detects it automatically. Plug it in, launch Gamescope, your games are there. No manual mounting or adding drives in Steam.
AMD SUPPORT
This has only been tested on Nvidia so far. Based on experience with the other distros, it should work on AMD out of the box — every other version has except Mint which needed a specific Gamescope patch for the RX 9000 series. If you're a member with an AMD card and it doesn't work, let me know and I'll get it fixed. That's exactly what happened with Mint and the turnaround was quick.

THE BWRAP THING
There's a bubble wrap error popup that appears occasionally on Fedora. It doesn't affect anything and games run fine. It's cosmetic and annoying. I'll look into suppressing it in a future update.

USING CLAUDE CODE ON A NEW DISTRO
Quick tip for anyone who bounces between distros — installing Claude Code as one of your first steps on a fresh system is like having a Linux expert on call. Instead of Googling Fedora-specific commands or hunting through Reddit threads, you can just ask it to set up your drivers or check your configuration. It's a genuine timesaver when you're working on an unfamiliar distro.

THE SCRIPT
The Fedora Gamescope launcher is going into the members area first. Once it's been tested across more hardware configurations it'll be released publicly. Currently available launchers cover Omarchy, CachyOS, Pop!_OS Cosmic, Linux Mint, and now Fedora. Ubuntu is on the list.
