Please how to make ets2 don’t run in full screen.

Because I can’t open the map editor.

Can someone help me please

When you are in the game (not the map editor), you can uncheck the box next to "Fullscreen mode" in the Options->Graphics screen. Or when your game is not running you can edit your "config.cfg" file in your home directory to change this line: to this:

I made the config.cfg step and didn’t open in full screen mode. But the problem is when I write edit Europe ets2 turns to black screen and it crashes.

So remove all mods from your mod folder and try again.
We won't be able to help you without your game.log.
