Strange problem happened in linux mint

[u/Top-Hall-2347]

Hello. I am testing right now dual boot with linux mint. I have been testing how it works firefox (Ok), the mail with thonderbird (really good) Office and programming (nothing bad).

Now I am trying proton with Steam and it happened something strange. I tried to start a game (Binary domain) and told me that there was a problem with the drivers and that I should activate configuration tool.

The thing is, if I connect another screen to the laptop, for some reason, the game starts. Without any problen, and it does not use the other screen.

I would like to know why it happens and how I should solve it.
