Linux Graphical Environment on Termux

In this article, we are going to see how we can install Graphical Environment on termux. Then, you may ask yourself what is the graphical environment.

A graphics environment file contains commands that specify exactly how a graph is produced.

Termux provides support for programs that use X Window System. However, there is no hardware acceleration for rendering, and the user will have to install a third-party application to view the graphical output. Before we continue let us see some definitions of keywords that we are going to use in this article.

What is X Window System?

The X Window System is a network-transparent window system that runs on a wide range of computing and graphics machines. X Window System servers run on computers with bitmap displays. The X server distributes user input to and accepts output requests from several client programs through a variety of different inter-process communication channels. Also, the most common case is for the client on networking and remote applications.

Setting up VNC Viewer – Graphical Environment on Termux

Server

• Install tigervnc in termux.

pkg install tigervnc

• After, installation you can now execute tigervnc with this command :

vncserver -localhost

At the first time, you will be prompted for setting up passwords. Then, set your password must be 6 or 8 characters and passwords are not visible when you are typing them.

Then, after you finish setting up your password, if everything is okay you will see this:

It means that the X (vnc) server is available on display ‘localhost:2’. Finally, to make programs do graphical output to the display ‘localhost:1’, set environment variable like shown here (yes, without specifying ‘localhost’):

Check if the VncServer is running or not. if it’s not running go back to the previous step.

Client

Now it’s time to install VNC Viewer from the play store. Then, if you have finished installing VNC Viewer, open it and start the configuration.

Now in the Address field Type localhost:1, Remember next time you run the server you need to change the localhost to 2 or 3. or You can type vncserver -list and you can see your localhost number there.
