How to View the Remote Desktop of a Headless Server
This is applicable to those people who do most of their works on CLI. But how about if a certain task requires that your server has a running X windows which is frequently not available on most linux-based servers? The answer is a virtual X server together with VNC.
We'll not tackle what is X server nor what is VNC, instead you may use the power of Google or just visit Wikipedia.
Requirements
Procedures
Before anything else, have a copy of an ssh client like PuTTY.
1. Install Xvnc
Using your ssh client, log in to the remote server and execute this command:
Or use this if you're using Ubuntu:
2. Start Xvnc
Once Xvnc is installed, start vncserver using the default display which is :0
Please note that Xvnc will ask for password on its first run. Better memorize it or write it down.
3. Start VNC Viewer
- On your local PC, lauch your VNC Viewer (which is portable TightVNC in my case)
- Enter the address of the remote server that you want to access
- Enter the passsword we used on step 2
- Then wait for VNC viewer to connect
You would see a gray background environment and that's it, you're now viewing your remote server's desktop.
To do a further test you may want to launch Firefox by issuing a command on your ssh client.

1. Install Xvnc
Using your ssh client, log in to the remote server and execute this command:
$ sudo yum install vnc-server
Or use this if you're using Ubuntu:
$ sudo apt-get install vnc4server
2. Start Xvnc
Once Xvnc is installed, start vncserver using the default display which is :0
$ sudo vncserver :0

$ sudo export DISPLAY=:0
$ sudo firefox google.com
