Black second screen but detected in Ubuntu 18.04












0















I have two GTX 1080 GPUs on my machine each connected with a DVI cable to a screen and the second screen is black but I still see my cursor on it so it is detected. The cursor turns into an X when I move it to the second screen.



I have installed nvidia-390 on my Ubuntu 18.04 64bits
