If you have issues with fullscreen FSO running on the wrong monitor or running across both monitors, try setting this in the script/terminal/etc that you use to run FSO:
export SDL_VIDEO_FULLSCREEN_HEAD=0
where 0 is the number (as reported by xrandr) of the monitor that you want FSO to run fullscreen on.
