3d 9h ago in linux_gamingI installed System76's Nvidia drivers, but then my second display couldn't work, and I read online that it's a common problem. Then I manually installed Nvidia's closed source driver instead, and now my second display works all fine.
EDIT: Now the game booted!
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:

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.
The overlay and launching games on Steam used to work, but after I had to reinstall Pop OS, they haven't worked.
