Hi guys, I am trying to install Faf on linux and running into an issue with protontricks (step 5 of https://wiki.faforever.com/en/FAQ/Client-Setup). I am able to install all the programs, and the protontricks folder populates, however, when trying to run ./protontricks 9420 dlls d3dx9 there is no executable file for it to run ('file or directory not found').
Aside from this, I am able to follow the installation guide, create an FA profile, and set up faf etc. The only issue is that FA gives me a black/frozen screen both in steam and FAF, presumably because I couldn't complete step 5.
I am running Ubuntu 20.0.4 with OpenJDK 17. So far I have tried proton experimental, 5.0, and 7.0-2. I have tried installing protontricks first and installing steam FA first. All other steam games and all features of the faf client are working well. Has anyone else had any experience with this?
edit: does graphics card matter? I am using Mesa Intel UHD Graphics 620 (KBL GT2) on my laptop.
