Big Update To My Gamescope Launcher - Laptops With Hybrid GPUs Now Work

Big update to the Omarchy Gamescope Steam Deck mode launcher. The script now supports laptops with hybrid GPUs — Nvidia discrete plus AMD or Intel integrated, MUX switches, offload mode, external monitors, the lot.

The desktop version has always been straightforward because you've got one GPU and one monitor. Laptops are a different world. You've got integrated graphics fighting the discrete card, HDMI output that might route through either GPU, MUX switches that change which card drives the panel, and offload mode where the iGPU handles display while the dGPU does the heavy lifting. Getting Gamescope to handle all of that reliably has been the hardest part of this entire project.

WHAT'S NEW

The launcher now has a setup step before you launch into gaming mode. It detects your monitors and GPU configuration, then lets you choose — which display to output to, what resolution, what refresh rate, and which GPU to use. For hybrid setups you pick between Nvidia discrete, AMD integrated, or offload mode depending on how your laptop is wired.

Save your settings, then Super+Shift+S to launch into Steam Deck mode as usual. Super+Shift+R to come back.

IMPORTANT — MONITOR SELECTION

Gamescope can only use one screen. If you set it for your external monitor at home and then unplug and take the laptop somewhere, it'll look for a screen that isn't there and you'll get a black screen. Always make sure your settings match your current setup before launching. If you do get stuck — Ctrl+Alt+F2 to drop to a TTY and kill the session. Recovery instructions are on the Git page.

TESTED ON

Acer Nitro — Ryzen 7 8845HS, AMD Radeon 780M integrated, RTX 3050 6GB discrete, external monitor over HDMI. Returnal at 1080p on high settings with DLSS quality pulled around 40 FPS. The GPU power draw looked lower than expected which might be an Acer power profile issue — my power control script on no-signal.uk fixes that for Nitro and Predator models.

TESTERS WANTED

I can only test on this one laptop. I need feedback from different hardware configs — AMD discrete GPUs, Intel plus Nvidia combos, machines with and without MUX switches. Please report issues on Git, not in the YouTube comments, so I can track and fix them properly.

THE SCRIPT

Updated on Git. Same install location as before — if you've already got the launcher, just pull the update.
