I wasn't able to run the game on an Ubuntu PC. Most of the time it just shows me an endless gray screen after the unity logo. One time I was able to see the main menu, but when I clicked the start button, I saw the black screen. I've made like 10 tries to run the game, but none was successful. The console output is non-informative, also I could not see any log files to provide. My config is: PopOS, i5 2400, r9 280x, ssd
