yes i put WaylandEnable=false in sddm.conf file under the [wayland] section.  
I’m struggling on it, on startup no errors are shown during boot but at the end of the boot my screen is totally turned off and it activates only if i switch terminal.

Try this: sudo nano /etc/gdm/custom.conf  
then, uncomment WaylandEnable=false. That worked for me, I hope it would be useful!
