If I only have twinview enabled with two monitors, KDE can distinguish between the monitors (fullscreen only goes to one monitor).
But if I enable the third monitor to be on a separate X, KDE only sees one monitor and fullscreens into both of them.
How can I enable my third monitor but still have nvidia report the monitor info to my DE?
xorg.conf with third screen disabled:
