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
