MangoHud displaying the wrong GPU in SteamOS game mode
Is there a way to configure MangoHud (or is it MangoApp in game mode?) to display the correct GPU? It’s displaying the stats for the integrated GPU in my CPU (Ryzen 7600X) instead of my dedicated GPU (AMD 7900 XTX). Adding ‘pci_dev=0000:03:00.0’ in ‘/home/bazzite/.config/MangoHud/MangoHud.conf’ isn’t working. I’ve also tried that in both presets.conf and mangoapp.conf.
It’s annoying because it was displaying the correct GPU a few days ago. I think a Steam system update might’ve broke it somehow.

The ‘sensors’ command is displaying my GPU with the fan and temps updating, so it isn’t because the sensors can’t be detected by the OS.
I think steamos-session is generating its own configs for MangoHud. I can see it’s creating files under ‘/tmp/mangohud.xxxxx’.
Solved by disabling the iGPU in the bios. Don’t be like me and assume it isn’t possible to disable the iGPU if you can’t find the setting. I should’ve RTFM for my motherboard.
