Dungeons 2 doesn't start

Hi everybody,
I’m having an issue with Gog Dungeons 2 on linux.
I have installed the game but it doesn’t start. My laptop is an Acer aspire 5755G, intel i5 2450M with an Nvidia 540M; I’m using Ubuntu gnome 18.04. Running the game from the terminal results in an error concerning the controller configs. Any ideas?
