How to install my Proton builds on Linux

Proton release notes are available at www.lumito.net/blog.

Requiremets

  • Latest Proton build (you can get it from here)

For scratch install only:

  • This bash script
  • Root (sudo) access
  • Python 3
  • At least 3.5 GB of disk space
  • Basic Linux terminal knowledge (cd, ls, apt, sudo, tar, etc.)
  • And a large cup of coffee (this will take some time)

Installing from scratch

  1. Get all the necessary files (Proton's .tar.xz and my proton bash script) and place them into a folder
  2. Extract the Proton base files
  3. Create the directory /opt if it doesn't exist (sudo mkdir /opt)
  4. Move the recently extracted Proton folder into /opt (sudo mv Proton /opt/). Now you should have a /opt/Proton folder with Proton base files located there
  5. Run chmod +x proton in the folder that contains my proton bash script to make sure it's executable
  6. Move the proton bash script to /usr/local/bin (sudo mv proton /usr/local/bin/)
  7. Install Wine. Go to wiki.winehq.org/Download, follow the instructions for your OS and make sure to install the development package, not the stable or staging ones. Proton doesn't require the wine executable, but it needs all of its dependencies to work properly. Meanwhile, drink the cup of coffee that you should have on your desk
  8. Run proton. You should get something like this after a few seconds:
    Traceback (most recent call last):
      File "/opt/Proton/proton", line 1264, in <module>
        g_session.init_session(sys.argv[1] != "runinprefix")
    IndexError: list index out of range
    
  9. If it shows that message, you're almost done. Finally, run proton run to prepare the main folder (default is ~/.proton, you can change it if you like by modifying the PROTON_OS_FOLDER var in my script)
  10. Go to ~/.proton and check if there are files there (pfx folder, version, etc.). If they are, then you are done! Now download some games and run proton run {EXEC_NAME} to execute them. If they require install, they'll be installed on ~/.proton/pfx/drive_c/{INSTALL_DIR}. You'll need to manually run the game, since the program doesn't create desktop shortcuts.

Updating your existing build

  1. Download my latest Proton build
  2. Fully delete the /opt/Proton directory
  3. Extract the new release into the /opt folder
  4. Run sudo apt update and sudo apt full-upgrade --autoremove --purge to upgrade all the system packages to ensure compatibility
  5. Execute proton run to update your ~/.proton directory (if needed)
  6. Done!
