    "xrandr" utility should help you with diagnostics and setup:
        $ xrandr -q
    
    Additional info:
        $ xrandr --listproviders
        $ glxinfo | grep -e 'glx' -e 'OpenGL' -e
      'display'
    
    Perhaps "nvidia-settings" utility could be a fastest way to
    configure dual-monitor setup and generate config file for Xorg to
    make settings permanent.
    I don't use dual-monitor setup myself, so I can't get you a clean
    example of how to configure it.
