Tried with Lightdm and 435 driver. Tried with Nvidia only and setting as "maximum performance".
Nothing.
Also I tried with only Intel and Wayland and it doesn't work neither. Seems a problem with Intel, I'm not sure. Nvidia detects the second monitor, it's just in blank screen.
I reinstalled from zero Ubuntu 20.04 and the second monitor is blank screen, tried with 3 monitors. Same result.
I'll back to 18.04 atm, over that version's working perfectly (except on-demand, because there's no option for that 'cause the version of Xorg on 18.04).
I hope find a workaround or at least a fix to this.
