I can’t launch games on Steam for some reason, at least Windows games using Proton. I even reinstalled Steam several times, but nothing has changed. My distro is Pop OS. Here’s what happens when I try launching Vanquish for example:

chdir "/home/quentin/.steam/debian-installation/steamapps/common/Vanquish"

This has something to do with Steam’s overlay, even though I have disabled it. Help is welcome.

    It could be that your specific hardware has some quirk about it which is not properly taken into account by the latest Proton…

    My GPU is GeForce 1070 and I naturally use Nvidia’s Linux drivers. My CPU is AMD Ryzen 7 1700. So I highly doubt my hardware is quirky in any way.

    I changed my client to a beta version and enabled the new experimental SteamRT3 Steam Client, as suggested. I have not enabled the Steam Overlay.

    Does Proton 9 work?

    Here’s what happens:

      Ok, I just did an entire write up and then shit canned it half way through because there’s a question I need to ask.

      I naturally use Nvidia’s Linux drivers.

      … which… ones?

      Because PopOS has its own way of doing Nvidia drivers.

      https://system76.com/support/articles/system76-driver

      Installing the System76 NVIDIA Driver for Systems with NVIDIA GPUs

      If your system has an NVIDIA graphics card, use this command to install the System76 Driver with NVIDIA graphics drivers included:

      sudo apt install system76-driver-nvidia

      In addition to the standard packages, this package also pulls in the System76-supported NVIDIA drivers and all related packages needed to take full advantage of your dedicated NVIDIA graphics card

      If you are manually trying to do your own Nvidia Linux driver install, on PopOS, that could cause some nonsense problems, where you would be in a state of essentially having 2, or kinda 1 and a half… sets of drivers installed at the same time, which would/could lead to bunch of extremely esoteric configuration problems, possibly including what you’ve reported so far.
