ETS2/ATS both not running on openSSUSE Leap 42.2

Hi,
I installed Linux versions of Steam and ETS2/ATS games in it, but none of them are running. I have shortcuts on my desktop and when I click them it happens… nothing. Nothing happenes also when I try to start either of the games from Steam. I checked the command under the shortcut and pasted it in terminal to see what’s going on. Here’s the output:

What the hell is going on and how can I fix it and run the game

Could you tell how your drives/partitions formatted and mounted?

The game should generate some kind of error message, I think it’s in the Steam directory, or somewhere in /usr. I can’t check it atm.
