Enable Remote Desktop on Ubuntu Linux

This post explains how to manage remote desktop sharing in Ubuntu Linux.

Why use this? Sometimes you need a friend or coworker to fix a computer problem while they are away. Remote desktop tools let them see your screen and control your mouse as if they were sitting right in front of your PC.

What happens when done? You will be able to securely share your desktop session with a trusted person, or keep it turned off to ensure your privacy.

There are many tools available, such as TeamViewer. However, Ubuntu Linux includes a built-in tool that works great for most users. It is part of the GNOME desktop environment.

On a Windows machine, open the Remote Desktop Connection app. Enter the hostname or IP address of your Ubuntu computer.

Ensure your Windows client supports modern RDP authentication methods. Note that if your Ubuntu session is running on Wayland, some older remote desktop clients may experience compatibility issues compared to a traditional X11 session.

Enter the username and password you set in the Ubuntu Remote Desktop menu to log in.

Once you enter the correct details, you will be connected to your Ubuntu desktop.

Conclusion

Ubuntu Linux has a powerful built-in tool for remote support. By using the GNOME settings, you can easily turn remote access on or off. Always remember to use a VPN for security, and ensure your Windows client is up to date to handle modern authentication requirements.
