I’m new to Linux, using Kubuntu. I got Left 4 Dead 1 installed from Steam and I’m using Proton 8.0. I get an error saying “An error occurred while launching this game: invalid app configuration”. Is there a launch option I should be using? Something else?

    When in doubt check out Protondb, it’s a database that says whether games work on Proton or not and people often put fixes there.

    Left 4 dead’s page is here: https://www.protondb.com/app/500

    It seems like it should work but you need to right click the game --> properties then add -w 1920 -h 1080 as launch options.
