Black screen when connecting to Raspberry Pi boards

When connecting to Raspberry devices which use Wayland, a black screen can show.

The workaround is to disable Wayland compositor.

RaspberryPi OS:
sudo raspi-config
Advanced Options -> Wayland -> X11 -> OK -> Finish -> Yes (to reboot)
 
Ubuntu 22.04 and newer:
edit /etc/gdm3/custom.conf as administrator and uncomment and set:
WaylandEnable=false
