Hello @JoveToo, https://gist.github.com/JoveToo/6fc5de394e94b2106f01eb4e57466f97#file-gistfile1-txt-L94-L120 is the section of your runtime diagnostics to focus on. The game's trying to run on your iGPU using mesa, but is failing because mesa currently can not render to a gui session running on the NVIDIA proprietary driver. DRI_PRIME=pci-0000_13_00_0 at https://gist.github.com/JoveToo/6fc5de394e94b2106f01eb4e57466f97#file-gistfile1-txt-L1721 seems like a hint. If you completely close Steam, then run steam from a terminal, does that have an effect?

JJoveToo 2025-12-24 github

Hi @kisak-valve, thanks! If I run steam from the terminal everything works fine!

Is there a way I can configure steam to never use the iGPU? It doesn't even have a monitor attached.

Kkisak-valve maintainer 2025-12-24 github

That implies that it's the desktop environment listening to PrefersNonDefaultGPU=true in Steam's desktop shortcut and setting DRI_PRIME.

JJoveToo 2025-12-24 github

I had some trouble identifying the right Steam.desktop but it indeed contained PrefersNonDefaultGPU=true. Removing that and rebooting solves the issue.

Thank you for the help and Merry Christmas, @kisak-valve!
