В итоге при старте иксов, запускаются все 3 монитора, но показывают только 2. Т.е. 2 монитора подключенные к nvidia показывают отлично, и в kde, в настройках они норамально определяются. А вот монитор подключенный к intel - просто черный экран. При том что индикатор питания горит, так как будто монитор показывает, и если к примеру выгрузить i915 (rmmod -f i915), пишет что пропал сигнал и гаснет.
и вот xrandr вот что кажет
