Remote Access and X11 Forwarding with Audio on Windows SSH to Ubuntu Server

Abstract: Learn how to remotely access a Ubuntu server via SSH and forward X11 graphics and audio from the Windows client.

Created: 2025-03-31 by UserComp.com Editors

To remotely connect to a Windows computer with a server running Ubuntu and display a GUI application using X11 while also forwarding audio, follow the steps below:

Install X11 on your Windows machine. You can download and install Xming or Cygwin.

On the Ubuntu server, install the x11-xserver-utils package:

sudo apt-get update
sudo apt-get install x11-xserver-utils

On the Windows machine, start the Xming/Cygwin X server.
On the Ubuntu server, obtain the X11 display number:
```
echo $DISPLAY
```
This will return a value like :0.0.
On the Windows machine, use the -X flag with the ssh command to forward the X11 connection:
```
ssh -X username@ip_address
```
Replace username with your username on the Ubuntu server and ip_address with the IP address of the server.
On the Ubuntu server, start the desired GUI application. The application should now be displayed on your Windows machine.
To forward audio, add the -Y flag to the ssh command:
```
ssh -Y username@ip_address
```

Now, you should be able to hear audio from the remote Ubuntu server on your Windows machine.
