Connect a Windows Laptop as a Second Monitor to an Ubuntu-Driven System: A Comprehensive Guide

Are you looking for a solution to extend your productivity by connecting a Windows laptop as a second monitor to an Ubuntu-driven system? There are several applications and methods available that can help you achieve this. This guide provides a detailed overview of the options available, including how to use each one effectively.

Understanding the Problem and Solutions

Connecting a Windows laptop as a second monitor to an Ubuntu system can enhance your multitasking capabilities, especially if you need to run Linux-specific applications alongside Windows programs. However, achieving this requires the right tools and methods. In this guide, we will explore various applications and methods, including open-source solutions and commercial software, to help you extend or mirror your desktop experience.

Popular Methods for Connecting Windows as a Second Monitor

Deskreen

Description: Deskreen is an open-source application that allows you to use any device with a web browser as a second screen. It works over Wi-Fi, making it a versatile choice for remote collaboration or personal use.

How to Use:

Install Deskreen on your Ubuntu machine. Open Deskreen and choose the screen you want to share. Deskreen will generate a QR code or a URL. Open the URL in a web browser on your Windows laptop.

SpaceDesk

Description: SpaceDesk is a software solution that extends or mirrors your desktop across multiple devices. It primarily works over a local network, ensuring a seamless experience even with limited internet connectivity.

How to Use:

Install SpaceDesk on your Ubuntu machine using Wine, as it is primarily designed for Windows. Install the SpaceDesk Viewer on your Windows laptop. Connect both devices to the same network and run the applications.

Input Director

Description: While primarily designed for controlling multiple computers with one keyboard and mouse, Input Director can also be used to share a display with a Windows laptop.

How to Use:

Install Input Director on both the Ubuntu and Windows machines. Configure the Ubuntu machine as a master and the Windows laptop as a slave.

Synergy

Description: Synergy is similar to Input Director and allows you to share a keyboard and mouse between devices, providing a seamless experience across both screens.

How to Use:

Install Synergy on both the Ubuntu and Windows machines. Set up the Ubuntu machine as the server and the Windows machine as the client.

VNC

Description: Using VNC (Virtual Network Computing), you can set up a VNC server on Ubuntu and connect to it from a VNC viewer on Windows. This method allows you to access your Ubuntu desktop from the Windows machine but does not create a true second monitor experience.

How to Use:

Install a VNC server on Ubuntu like TightVNC or TigerVNC. Install a VNC viewer on your Windows laptop. Connect to the VNC server using the viewer.

Conclusion

Each of these methods has its own advantages and limitations, so the best choice will depend on your specific needs. If you are looking to extend your desktop, SpaceDesk, Deskreen, and Synergy are excellent options. For seamless keyboard and mouse control, Input Director and Synergy are the preferred choices. If you only need access to your Ubuntu desktop, VNC is a reliable solution.

Remember, the setup process can vary depending on your operating systems and network configuration. Always ensure that both devices are connected to the same network for optimal performance. By choosing the right method, you can unlock the full potential of your dual-monitor setup and enhance your productivity.
