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.

      I tested with another Windows game, BattleBit Remastered. It booted up all fine. Vanquish on the other hand stopped after the logos for Sega and PlatinumGames. Looks like this is not a problem with Proton and my system configuration, it’s a problem with Vanquish, that game doesn’t seem to run with newer Proton versions.

        Yeah, I am inclined to agree with your assesment… my first thought was that maybe your steam install had somehow gotten misconfigured and ended up in a situation where some dependency hell was going on.

        But… that doesn’t seem to be happening…

        https://www.protondb.com/app/460810

        People are saying it does work with Proton 10.0.3.

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

        Does Proton 9 work?

        Maybe Proton-GE or some other variant?

        May be the case that you’re a real guinea pig, a real test subject on this one, might have actually found a real bug in Proton 10.

          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:

          Proton 9 results

            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.
