This tutorial shows how to remote access Ubuntu desktop from Windows 7 using x11vnc server.

In Ubuntu install and setup x11vnc server:

Open up a terminal from the dash or press Ctrl+Alt+T.

  • 1. Install x11vnc in ubuntu via command:
    sudo apt-get install x11vnc
  • 2. Set vnc password and it’ll be encrypted and saved in ~/.vnc/passwd:
    x11vnc -storepasswd
  • 3. Start vnc server:
    x11vnc -forever -shared -rfbauth ~/.vnc/passwd

NOTE: If you connect from outside local network, get the Ubuntu’s global ip, and on your router, setup your connection via DMZ. Once you are able to establish a connection, put on all the security like firewalls.

If you want this VNC Server auto-start at login, do following steps:

  • 1. Copy and paste password file to /etc/ directory:
    sudo cp ~/.vnc/passwd /etc/x11vnc.pass
  • 2. create and edit file /etc/init/x11vnc.conf via
    sudo gedit /etc/init/x11vnc.conf

    copy and paste following and save the file.

    start on login-session-start
    x11vnc -display :0 -auth /var/run/lightdm/root/:0 -forever -bg -o /var/log/x11vnc.log -rfbauth /etc/x11vnc.pass -rfbport 5900 
    end script
  • 3. reboot.
