Usually your window manager or compositor decides that...
@d3rrial Although my window manager is not very sophiscated, I tried setting initial position and ignoring initial settings. Nothing changes as if the window doesn't care about the settings.
Do you have a similar setup and can confirm you can configure the screen?
@ml- Sorry, no, I use Gnome right now, stuff just works for me.
@d3rrial So what is it. You don't have a external monitor to test it. Or do you have one and it works?
I have 2 monitors, games always start on the primary monitor, but I can just grab it with the mouse and drag it to the other screen and then it's rendered there
Are there parameters I can pass to Proton to force a screen?
$ DISPLAY=:0.1 someapp ?
format: "hostname:D.S", commonly used value :0
@pchome Right now it can't find a display under :0.1. But thanks for that information, now I know where to start looking.
Check this SO answer on the XOrg DISPLAY environment variable. Unless you're not using XOrg (which is uncommon for Linux), this is how you would adjust the monitor selection. It's not a given than :0.1 will work - it depends on how XOrg is configured.
@Qix- Yes, that's the problem. Also, my Window manager doesn't seem to handle such a thing (JWM).

My screen setup:
Problem:
Game (e.g. GTA:SA) always starts on primary screen (1).
I couldn't find a way to change the screen used by the game.
Which component decides what screen to use for the game? Proton/Wine or the game itself?
