Remote Desktop X11VNC

x11vnc is a tool that allows administrators to connect to the server's
real X desktop directly through the VNC Viewer.

Debian

EC-A1684JD4 FD has installed the xfce4 desktop and configured the
x11vnc related environment by default. The user directly executes the
following command to wait for the connection:

   sudo x11vnc -display :0 -auth /var/lib/lightdm/.Xauthority &

Then you can use "$bm1684_ip:0" address to VNC remote connection on
the PC.

The following is the specific operation process of VNC Viewer:

(1) The user first downloads

VNC Viewer

 from the official website, and selects the corresponding installation
package according to the PC system to download and install.

(2) After the installation is complete, open VNC Viewer and skip
login:


(3) Enter "$bm1684_ip:0" address of EC-A1684JD4 FD:


(4) Enter the user and password, both "linaro":


(5) Successfully entered the xfce4 desktop:
