X11VNC is the popular VNC server for creating remote desktop connection and access remote desktop. It works will almost all the desktop environment available for Ubuntu and Debian based systems. Using remote desktop connection we can connect any remote system and access graphical user interface and work. We can use any available vnc viewer like the tight vnc viewer, real vnc viewer or ultra vnc viewer.
X11VNC can be a better remote support software for you. This tutorial will help you to setup x11vnc server on your Ubuntu, LinuxMint & Debian system and connect using vnc viewer from the client system.
Step 1 – Install X11VNC
X11vnc packages are available under default repositories, So just update default repositories and install.
sudo apt-get update sudo apt-get install x11vnc
Step 2 – Create Password
Now create a password to connect using vnc viewer from client system.
x11vnc -storepasswdEnter VNC password: *********Verify password: *********Write password to /home/rahul/.vnc/passwd? [y]/n yPassword written to: /home/rahul/.vnc/passwd
Step 3 – Start X11VNC Server
After successful installation of x11vnc server on your system. Let’s start it using the following command. Change the parameters as per your setup.
sudo x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth /home/rahul/.vnc/passwd -rfbport 5900 -shared
The VNC server will start on default port 5900. In case the port 5900 is busy with some other service, it will automatically select the next available port like 5901.
Step 4 – Connect from VNC Clinet
To connect to the server using VNC, you need a VNC client on your system. For this tutorial, I am using RealVNC viewer on our system. You can use any other client of your choice.
Step 5 – Setup AutoStart on Boot
Finally setup the auto start of x11vnc server on system boot. Create a x11vnc.conf file under /etc/init/ directory using following content.
sudo vi /etc/init/x11vnc.conf
# description "Start x11vnc on system boot" description "x11vnc" start on runlevel  stop on runlevel [^2345] console log respawn respawn limit 20 5 exec /usr/bin/x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth /home/rahul/.vnc/passwd -rfbport 5900 -shared
