About remote desktop connection to ROCK 3c

#1

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.

Port opened on ROCK 3C.

P.S.: Does anyone know why the ROCK 3c GUI desktop screen cannot be displayed from the Windows remote desktop?
thank you

#3

@s_ikeda can you have a try on this guide https://docs.radxa.com/en/radxa-os/config/remote-login

#4

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.

After that, I was curious about the following screen being displayed when the system starts up, is there something to do with it?

#5

please have a try again

1、sudo apt install xfce4 xfce4-goodies xorg dbus-x11 x11-xserver-utils -y
2、sudo apt install tigervnc-standalone-server tigervnc-common -y
3、vncserver – create password
4、vncserver -kill :1
5、sudo touch ~/.vnc/xstartup — Add these content below
#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
exec startxfce4
6、chmod 777 ~/.vnc/xstartup

#6

Yep. I remember it took me a lot of time finding the solution for setting remote desktop, and it was installing tigervnc.

Also, you should log out from the active desktop session before accessing it remotely.

#7

Thank you for your advice.

I executed the following command:
— cmd 1 --------------------------------------------

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.
