Hi,
from a Raspi 2 and 3 I make a ThinClient with this project
Raspberry Pi Thin Client project
When I start Pi Desktop, the OS starts clean.
When I shut down the OS, the Raspi goes out.
The Pi Desktop board stays on, so I can't switch on the Raspi anymore.
I would have to unplug the circuit board, but that doesn't make any sense anymore.
bye
Markus
