I have dual Geforce GT1030's, with 4 monitors. I'm attempting to enable all 4 such that I can use each of them in an extended monitor display.

I've run sudo add-apt-repository ppa:graphics-drivers/ppa, and selected nvidia-384.111, 390.25, and 387.34, in either event the very moment that I change: Option "Xinerama" "0" from 0 to 1 and reboot, the screen boots, I get the purple screen, and then it goes black. Black like the monitors are life (I can see the cursor) but no ubuntu session or login screen.

On 384.111, I disabled Wayland entirely under the gdm3 config to see if somehow that was an issue, but it didn't seem to change anything (The nvidia driver seems it might do this by default?).

Below is my xorg.conf for possible reference:
