How to Use a Tablet as a Monitor for a Computer in Linux

Using a tablet as a monitor for a Linux computer can be a practical solution for remote work, multimedia streaming, or simply extending your display. This guide will walk you through several methods to achieve this, including leveraging SSH, remote desktop software, and Chromecast.

Setting Up SSH Access for Your Linux Computer

One of the most flexible ways to control your Linux computer from a tablet is by using SSH (Secure SHell) to access the computer's terminal as if it were a remote terminal session. This method is ideal for sysadmins or power users who require a secure and efficient access method outside the local network.

Prerequisites

Your Linux system must have an SSH server daemon (like OpenSSH) running. Your tablet should be able to connect to your network over WiFi or data. An SSH client app on your tablet for connecting to the Linux machine.

Steps to Set Up SSH Access

Enable SSH on the Linux machine: You can enable the SSH service by editing the /etc/ssh/sshd_config file or using the package manager. Install an SSH client on the tablet: Popular choices include Termius, PuTTY, or any other SSH client with a user-friendly interface for the tablet's operating system. Connect via SSH: Use the tablet's SSH client to connect to the IP address or hostname of your Linux machine using appropriate credentials.

Many sysadmins, like the one mentioned in the article, use this method when they need to manage their Linux systems remotely using their mobile phones tethered to a data connection. This setup ensures secure and efficient remote management.

Streaming Media with Chromecast from Ubuntu

For users of Ubuntu, integrating a tablet as a monitor for a computer can also be done through the Chromecast feature. This provides a high-quality multimedia streaming experience that is both user-friendly and scalable.

Prerequisites

Ubuntu Linux as the operating system on your computer. A compatible Android tablet. Chromecast app on the Android tablet.

Steps to Set Up Chromecast

Install the Chromecast app on the tablet: The Chromecast app is available on the Google Play Store. Pair your tablet with the Chromecast device: Follow the on-screen instructions to complete the pairing process. Start streaming: Use any media player on Ubuntu to cast the content to your tablet via the Chromecast app.

Users can enjoy multimedia content from Ubuntu on their tablets, making it ideal for entertainment, presentations, or educational purposes.

Using Remote Desktop Software

Another effective method is to use remote desktop software, such as TeamViewer. This option allows you to remotely control a Linux machine from a tablet, offering a desktop view of the computer's screen and full interaction capabilities.

Prerequisites

TeamViewer installed on the Linux computer (free for personal use and business applications). TeamViewer client app installed on the tablet.

Steps to Set Up Remote Desktop with TeamViewer

Install TeamViewer on the Linux computer: Visit the official website to download and install the software. Install the TeamViewer app on the tablet: TeamViewer app is available on Google Play Store. Connect using TeamViewer: Share the remote session ID or create a new session to allow the tablet to connect to the Linux machine.

With the tablet functioning as a desktop client for the remote system, you can work on your Linux projects or manage your system from the comfort of your tablet. This method is particularly useful for cross-platform development or when working in environments where a full keyboard and monitor setup might be unavailable.

Conclusion

Using a tablet as a monitor for a Linux computer can greatly enhance productivity and accessibility. Whether you choose to use SSH for secure terminal access, Chromecast for media streaming, or remote desktop software for full control, these methods offer a versatile and technologically robust solution. Experiment with these different methods to find the one that best suits your needs.
