Every game crashes on boot if eGPU is connected

[oromis995]

• Steam client version (build number or date):

• OS - XFCE Manjaro :
  6.1.22-1-MANJARO
  X Server Vendor: The X.Org Foundation
  X Server Release: 12101008

• Not opted into Steam client beta

• System updated to latest stable Manjaro version

Description

Upon launching most games with a connected eGPU, the game will crash on boot. This includes Fractured Space, Empyrion Galactic Survival, Elite Dangerous and many others. The only one that does not crash is Stellaris for some reason. I have attached my stack trace. Compatibility options do not seem to make a difference which leads me to believe it's a driver issue of some sort. Python applications and 3D modeling applications are able to use the eGPU just fine, so it's not an issue with the GPU itself.

Thanks!

Hello @oromis995, in general, we're tracking issues with games run with Proton in the Proton issue tracker, so I've transferred this issue report.

Please add PROTON_LOG=1 %command% to a couple affected game's launch options and attach the generated $HOME/steam-$APPID.log to this issue report as a file. (Proton logs compress well if needed.) Also, please note which video card and driver version you're using externally.

In general this reads like a video driver issue and this should also be mentioned to your video driver vendor.

Thank you for taking the time to look at this and answering so promptly @kisak-valve .

I am running an Nvidia RTX 2060 12GB over Akitio Node Titan with drivers 530.41.03 according to the Nvidia Server Settings.

According instead to the cli a full list of video drivers installed can be found:

Per your request I am also attaching the protonlog which applies to Empyrion Galactic Survival:
steam-383120.log

Thank you again and please let me know if there is anything else I can do to facilitate the resolution.

Sincerely,

oromis95
