I used TightVNC on the PC side and x11vnc on the Arduino side.
The issue is that many users don’t even realize SBC mode exists simply because they rushed to buy the board thinking it was “just a more powerful Arduino”, without watching the presentation or reading the documentation.
That’s why I think this feature could be highlighted more clearly — for example by adding a native remote desktop function directly inside AppLab.
It would make the SBC capabilities much more visible and accessible for new users.
P.S. I’m not sure why, but for some reason I thought the UNO Q’s Linux distribution was called “Arduino OS”. In my head, the board was running a proprietary Debian‑based system rather than Debian itself.
