I wanted to connect to Rock 3c, Debian Bullseye from a Windows 10 PC using Windows 10 standard remote desktop software, so I executed the following command.
1) Tightvncserver installation command: “sudo apt install tinyvncserver”
2) xrdp installation command: “sudo apt install xrdp”
After running each, I entered the Rock 3c's IP address from my Windows PC to establish a connection, but the Rock 3c's desktop does not appear even after entering the ID and password.
However, you can connect using another character terminal software (CUI).
You can connect to Raspberry-pi (stretch) using remote desktop on Windows-PC.
Thank you for your advice.
I followed the remote login procedure, but unfortunately I cannot log in using the GUI from a Windows-10 PC.
I am attaching a copy of some of the screens below.
— Start ----------------------------------------------------------------------------
rock@rock-3c:~$ vncserver
New Xtigervnc server ‘rock-3c:1 (rock)’ on port 5901 for display :1.
Use xtigervncviewer -SecurityTypes VncAuth -passwd /home/rock/.vnc/passwd :1 to connect to the VNC server.
rock@rock-3c:~$ vncserver -kill :1
Killing Xtigervnc process ID 1063… success!
rock@rock-3c:~$ vncserver -localhost no
New Xtigervnc server ‘rock-3c:1 (rock)’ on port 5901 for display :1.
Use xtigervncviewer -SecurityTypes VncAuth,TLSVnc -passwd /home/rock/.vnc/passwd rock-3c:1 to connect to the VNC server.
New Xtigervnc server ‘rock-3c:1 (rock)’ on port 5901 for display :1.
Use xtigervncviewer -SecurityTypes VncAuth -passwd /home/rock/.vnc/passwd :1 to connect to the VNC server.
Next, I tried connecting to Rock-3c with “RealVNC Viewer 7.8.0 (r51458) x64 (Nov 2 2023 16:07:13)” on Windows 10.
At the same time, I monitored the protocol using Windows 10’s “WireShark”, but data was sent to Rock-3c’s 5901 port using UDP, but Rock-3c disconnected at RST-ack.
Next, attach the “~/.vnc/rock-3c:5901.log” file.
An error or warning has occurred.
I’m thinking that there’s probably something wrong with the settings.

My alternative to TigerVNC is x11vnc. It is useful if you need to see existing physical display (e.g. for headless login without keyboard) or just use it without physical display. Though, the output of x11vnc is slow (probably due to my poor WiFi connection to Radxa Zero 3W).
