[Bug 207901] Nouveau: In a 4 monitor setup, 1-2 displays remains black after boot

--- Comment #31 from Maurice Gale (mauricegale1@gmail.com) --- Sorry for the late reply, I too was working a different project.

To answer the above questions:

1. Only the main screen is displayed during grub, the other are displayed once Ubuntu finish loading.

2. I have tried modesetting DDX, but got the same results.

3. I have also tried wayland, but got the same results.

I have also tried starting off with 1 display, then 2 and so on. I have noticed that it can consistently load 3 displays. The trouble seems to occur once the 4th display is introduced.

I also get the occasional all displays booting black when 4 displays are connected.
