I have to monitors, one attached to my Nvidia graphics card using HDMI, the other one using VGA (using a DVI-VGA adapter). Most fullscreen games (that even recognizes that there are two monitors) uses the secondary monitor. The primary monitor is correctly set when I check from nvidia-settings,
xrandr or KDE system settings.
My current workaround is to simply disable monitor 2 when playing a game but that's not satisfiying. How can I effectively set the primary screen?
