Screen is off

Could you try running in single monitor mode and see what happens?
You should not edit the default_settings.cfg file, that is the file the game uses to create the user settings.cfg file. I can't recall exactly where but in your home folder you should find a settings.cfg file in a Frictional or Penumbra .folder

It works fine when I disable twinview and go back to 1 monitor.

I looked around the Overture folder and couldn't find the user settings.cfg. I wanted to edit it manually to try the game not fullscreen to see if that would work with dual monitors. Or do I have to copy the default settings file and rename it to settings.cfg?
