Troubleshoot

• mss.exception.ScreenShotError: XGetImage() failed

  Gnome using Wayland instead of Xorg as the default video output and Wayland doesn't support screenshot (python-pillow/Pillow#6312). Change the Wayland to Xorg will solve this problem. Follow the following steps:

  1. Modifying /etc/gdm3/custom.conf to uncomment #WaylandEnable=false
  2. Ran sudo systemctl restart gdm3 to restart it so Ubuntu is using X instead of Wayland. python-pillow/Pillow#5130
