Hi, I am trying to use PaperTTY with Pi Zero 2 with Waveshare IT8591 6"HD ePaper screen and get visual data from VNC. Overall it works correctly - but only if I connect to same VNC server with my PC.

The setup is:

  1. Windows PC with RealVNC Viewer
  2. VM on Windows PC with Debian running VNC server
  3. PiZero2 with epaper running PaperTTY

If I just run PaperTTY (3) to server (2) without ALSO connecting from PC (1) it just stands there. But if I connect with PC - it starts getting updates.

Just checked: When I run PaperTTY on VM (2) - with bitmap as driver - it works in the same way

Did anyone else also experience this issue?

Sorry for the late reply. That sounds odd, not sure off the top of my head why that would happen but possibly some authentication related thing with RealVNC? I recall some others have had difficulties with that, see https://github.com/joukos/PaperTTY/issues/80#issuecomment-883096518 and the linked issue #72 - it's a bit long thread but possibly something useful there.
