Norns on vnc viewer

Appreciate some help in connecting to Norns with VNC. I’ve enabled RealVNC via raspi-config and can connect using VNC Viewer on my iPad but it just displays and black screen with the message ‘Cannot currently show the desktop’. Any advice?

The standard norns software image does not include a desktop environment which could well be the reason for the black screen. Using an ssh client on the iPad is probably an easier and less resource intensive solution assuming shell level access is the goal.
