Fedora 43 KDE Plasma just got the Gamescope Steam Deck mode treatment. Same concept as the GNOME version from the last Fedora video — install the script, press a keybind, and you're in a pure Gamescope gaming session. Press another to get back to your desktop.
This one's for Plasma 6 on Fedora 43 with Nvidia. A couple of people in the members area asked for it since KDE Plasma is arguably more popular than GNOME for desktop Linux users, so here it is.
THE INSTALL
Same process as every other version. Drop the script into your downloads, drag it into a terminal, run it. It handles the full setup — Steam, Gamescope, ProtonGE, session switching, the lot. If you've already got Steam and Gamescope installed from the GNOME version, it'll detect them and skip those steps.
Make sure your Nvidia drivers are up to date before running. I'm on driver version 5080. Should work on AMD but I haven't tested it yet — if you're a member with an AMD card, give it a go and let me know.
There's a Steam bootstrap step where it downloads, asks you to log in, adjust settings, then close and exit Steam. The script will sit there blinking waiting for you to press Enter to continue. Don't panic, just press Enter.
Reboot after the install. The keybinding setup on Fedora needs it.
LAUNCHING AND EXITING
The keybind is Super+Alt+G to launch into gaming mode — note that's different from the GNOME version because KDE Plasma maps keys differently.
Once you're in, set up as usual. Lock resolution to 1440p if you're on Nvidia to avoid artifacts above that. Switch off HDR if your monitor doesn't support it. Right-click games to force ProtonGE compatibility.
Exiting is done through Steam's own menu — Power, Switch to Desktop — same as on a real Steam Deck. I couldn't get Super+Shift+R working on Plasma 6, it was throwing errors. Might be a KDE-specific issue. The Steam exit method works perfectly though and you're back on your desktop in seconds.
THE SCRIPT
In the members area now. Once it's been tested more widely it'll go up on the public GitHub alongside all the other Gamescope launchers — Omarchy, CachyOS, Pop Cosmic, Linux Mint, and Fedora GNOME.
