Secondary monitor is blank screen on KDE

Hey guys, I have just installed KDE plasma.

When I have setted up my dual monitor, everytime I reboot the PC, when I log in the secondary monitor is blank. On top of that all the icons in hte main primary folder do not appear. I can move my mouse over to the secondary blank screen and can see it and I can move windows to it, but the wallpaper does not appear at all unless if I disable it and enable it again through the settings.

Any idea how to resolve this?

Are you using Wayland or xorg?

xorg mate

journalctl --user -b  -p4
grep -E "\(EE\)|\(WW\)|failed|error" /var/log/Xorg.0.log

Got the same problem before I switched to EndeavourOS from Manjaro and I found this:
