freezing when an external display is connected

I'm using ubuntu(16.04) in my macbook(cpu:core 2 duo, graphic:NVIDIA GeForce 9400M). When I connected an external display via hdmi-minidisplay cable, my macbook built-in display began to flash and freeze(no response for click). Why this happens? How can I fix this ?

1 Answer

I fixed this promblem by myself. I changed GeForce 9400M driver to Nvidia binary driver from x server by GUI(Additional Drivers). It worked.
