Hi all
I read in a forum that modern versions of KDE/Kwin do not support more than one xscreen and I want to know if it is true.
I need two xscreen, one for the desktop via DVI and the other for Kodi via HDMI.

Equipment summary:
Host CPU: AMD Ryzen 5 3400G with Radeon Vega Graphics, 8 cores available
Running on KDE neon User Edition 5.19 18.04, kernel: Linux x86 64-bit version 5.6.12-20.05.10.amdgpu.ubuntu

The configuration is with xorg.conf and will be similar to this:
