The Linux Mint Gamescope Steam Deck mode launcher has been in the members area for about a month. Members have tested it, bugs have been squashed, and now it's going public. If you're on Mint and you want to play Steam games properly through a dedicated Gamescope session, this is for you.

Mint is where a lot of people land when they first switch from Windows. It's comfortable, familiar, and it just works. But gaming through the desktop can be hit and miss. This launcher strips all of that away — press Super+Shift+G, your desktop shuts down, Gamescope takes over, and you're in Steam Deck mode. If it works on a Steam Deck, it works here.
THE INSTALL
Download the script from no-signal.uk or the Git repo, drag it into terminal, run it. Make sure you've already installed the Nvidia drivers through Mint's driver manager before running — pick the latest version, not nouveau.
The install is longer on Mint than on Arch-based distros. Gamescope has to be compiled from an older version because Mint's packages aren't as current as rolling release distros. MangoHUD gets built from source too. Budget about 10 minutes on a decent machine. If you get mirror errors during the download phase — and I got several on a fresh install — just rerun the script and it'll retry and pick up anything it missed.
Steam gets bootstrapped during the install. Log in, go to Settings, switch off shader cache under Downloads, exit Steam, press Enter to continue. Same process as the Fedora and Nobara versions.
Reboot after the install.
LAUNCHING AND EXITING
Super+Shift+G to launch gaming mode. First launch takes a moment. You'll get some initial flickering in the Steam interface but it doesn't carry into games.
A few settings to tweak on first launch — lock resolution to 1440p on Nvidia, switch off HDR if your monitor doesn't support it, disable Wi-Fi in the Steam settings if you're on a wired connection to stop it hunting for the wrong network adapter. Go to Control+F2, advanced settings, and disable the frame rate limit or you'll be capped at 60fps.
To exit — Steam, Power, Switch to Desktop. Same as a real Steam Deck.
THE MINT QUIRKS
Mint runs an older package base so GameScope has to be built from a version or two back. It works fine but you won't have the very latest features. MangoHUD can show inaccurate frame rates on this build — use the built-in Steam overlay if you need precise numbers.
Mirror errors during install are a Mint thing, not a script thing. The default mirrors sometimes return bad requests. Rerunning the script sorts it.
Arc Raiders crashes on first launch every single time on my system, on every distro. Relaunch it and it works perfectly from then on. I've never bothered to investigate why.
NOT TESTED ON LAPTOPS
Desktop only for now. The script looks for a monitor attached to the discrete GPU. If you're on a laptop without an external display on the dGPU, results may vary. Give it a go and let me know.
THE SCRIPT
Available on no-signal.uk and the Git repo. Download it, clone it, fork it, do what you want with it.
