After reading this post:
https://community.victronenergy.com/questions/93218/generic-touchscreen-on-cerbo.html
I bought the 7" WaveShare touchscreen linked in the post. I have a Cerbo-S, not the full model. The touchscreen is just blank, the backlight will come on for a few seconds but I never get any display at all. Some folks have said this screen is plug and play and it works out of the box,
I am connecting the display via USB, plugged into the middle USB port on the Cerbo-S and the Touch port on the screen.
I have tried plugging in the HDMI cable just to see what happens, the backlight comes on but still no display.
I tried running the commands in that doc via SSH but I get a file not found or something error at this stage:
