This worked for me while Chocolate Doom and Crispy Doom both refused to run. You can drop your WADs in /usr/share/games/doom and create a launcher with the execuatable name, path and map, e.g. "dsda-doom /usr/share/games/doom/nuts.wad" (No qoutes unless you have a space in there.) Make sure you have Doom1.wad and Doom2.wad in there for custom maps to run properly.This is on Mint Cinnamon 22.3. Happy DOOMing!
