Hi, I recently installed pop!_os on my shiny new gaming desktop and I’m loving it so far. But I’m now trying to get some games to work (mostly Helldivers 2 right now, which does work after a fresh install, but then freezes on a blackscreen with all subsequent launches. I’m assuming this is due to that awful kernel level anti cheat somehow)

Long story short, according to the fine folks over at protonDB, gamescope can help. But I can’t find it on the pop shop or with apt-get. If anyone can point me to some trusted PPA I can use, or the dependencies I need to build it from source, that would be very appreciated (or even, just how to find out what dependencies I am missing. I lost my linux-fu after a long period of using Windows exclusively but I’m not a complete noob)

Additional infos : I used the Nvidia installer, 550 drivers (I have the RTX 3080 Ti), have the Nvidia drm modeset enabled, and I’m using the pop_os Steam package. I also enabled “force full composition pipeline” in Nvidia settings actually I just disabled it because it was causing issues with some other games that were running fine without it

    I have not tried to run a ton of games, but so far, Darktide runs pretty much as well as I could have expected, and helldivers 2 runs great too, but so far I have not found a way to play it twice without reinstalling it. I have a weird issue with V rising displaying some debug texture in the main menu but other than that it has no major issue either.

    Idk what you tried with pop OS, and you probably don’t need this advice anymore, but I do have a somewhat similar setup (7900X 3D, 3080 Ti) and I couldn’t get anything to run without the 550 drivers (I had the 470 version installed by default) nor the flatpak version of Steam, in case that helps anyone seeing this.

      I gave PopOS a shot 2 months ago, just the latest nvidia iso from the time, not sure which display manager but having better luck now with Wayland and KDE 6. I do run dual 1440p 144Hz VRR monitors and I think most Linux OSs struggle with that, hoping to try Nvidia driver 555 with explicit sync.
