New build with 2 Geforce 710 cards and 3 monitors. Loaded Ubuntu 16.04. and with the standard driver all 3 monitors showed in system settings => display. But, experienced problems such as screen flicker, occasional system freezing and could not get i1Display to perform calibration. I downloaded/installed 364.19 using system settings => software & hardware but now only one display is active. Followed the steps Install Nvidia driver instead nouveau but still not working.
Interestingly, the mouse shows as an X on the other two monitors when I scroll to the left from primary monitor. However, system settings => display only shows one monitor. The monitor that display is the only monitor plugged into one of the cards. The other two monitors are both plugged into the second card.
Does anyone know how to resolve?
