How to Use an Android Tablet as a Monitor for a Linux Computer with USB

For those looking to extend their computing experience by leveraging an Android tablet, there are various methods to achieve this, especially when working with a Linux computer. Whether you are a beginner or an experienced user, this guide will help you set up an Android tablet as an extended monitor or a secondary display for your Linux computer. This article discusses several methods, including using SSH, remote desktop software, and Chromecast integrations, all while ensuring optimal performance and user-friendliness.

Method 1: Setting Up SSH for Remote Access

For remote access and SSH functionality, you can use your Android tablet to securely connect to a Linux computer. This method requires the tablet to have an SSH client installed and the Linux computer to have an SSH server enabled. The setup is particularly handy for sysadmins who need to manage servers remotely.

Steps:

Install an SSH client on your Android tablet (e.g., ). Ensure that your Linux computer has an SSH server running (typically avahi-daemon for networking). Use WPS (Wi-Fi Protected Setup) or another method to connect both devices to the same network. Configure the SSH client to connect to your Linux computer using the appropriate IP address and credentials.

My sysadmin prefers this method because it provides a secure and reliable way to manage his Linux computer, even when he's working remotely from his mobile phone. Using a dedicated SSH terminal also allows him to execute commands and manage the system without sacrificing security.

Method 2: Remote Desktop via USB Connection

For more interactive and visual tasks, setting up remote desktop on your Android tablet connected to a Linux computer via USB can be a game changer. This method is useful for situations where you need a full graphical user interface.

Steps:

Install a remote desktop software on both the Linux computer and the Android tablet. Popular options include TeamViewer and AnyDesk. Connect the Android tablet to the Linux computer with a USB cable. Both devices should be on the same network or the USB connection should be stable enough for secure communication. Run the remote desktop client on both devices and pair them via the software.

TeamViewer, for instance, is free for personal use and widely regarded as one of the best remote desktop solutions. It acts as a client on the Android tablet and a server on the target PC, enabling you to control the Linux computer as if you were sitting in front of it.

Method 3: Chromecast for Display Sharing

If you are using Ubuntu, you can leverage the Chromecast functionality to stream your Ubuntu interface to your Android tablet. This method is particularly useful for presenting content or mirroring your desktop. While not as powerful as a full remote desktop, it is simpler to set up and still offers a useful visual extension.

Steps:

Ensure that the Chromecast functionality is enabled on both your Linux computer and your Android tablet. Install the necessary software on both devices. On the Linux computer, install the ChromeCast Media Extensions. On the Android tablet, ensure you have the latest version of the Chromecast app installed. Pair the devices through the Chromecast app. Start the Chromecast stream from your Linux computer, and your tablet should display the Ubuntu interface.

Chromecast is a particularly useful tool for presentations, education, or streaming media directly to the Android tablet without the need for complex configuration.

Conclusion

By using these methods, you can harness the power of your Android tablet as an extended monitor for your Linux computer. Whether you need secure access via SSH, a full-featured remote desktop environment, or simple display sharing, the options are vast and cater to a variety of use cases. Experiment with these methods to find the one that best suits your needs. Happy computing!
