Alright, Lets's get this straight, these are just some dotfiles, which will help you to setup a graphical environment in termux. It's kind of a backup for me as well.

This repo contains config files, some useful & important scripts. I'm trying to make it a step by step guide to setup a beautiful linux desktop in your android device with termux, So follow the steps and you'll end up making it look like this -

Lets's start with the beginning...

What is termux?

Termux is an Android terminal emulator and Linux environment app that works directly with no rooting or setup required. A minimal base system is installed automatically - additional packages are available using the APT package manager. More Here...

How To install termux?

At first start a small base system is downloaded, And brings you to a minimal bash shell.

Configuration

Now all the necessary programs are installed, it's time to configure the system.
So, first clone this repo by,

cd $HOME && git clone https://github.com/adi1090x/termux-desktop

Now go to the cloned directory termux-desktop and copy or move 'home' & 'usr' directories to /data/data/com.termux/files. you can do it by,

cp -rf ./home /data/data/com.termux/files && cp -rf ./usr /data/data/com.termux/files

or

mv -f ./home /data/data/com.termux/files && mv -f ./home /data/data/com.termux/files

Warning : I'm assuming you're doing this on a fresh termux install. If not so, please backup your files before running these command above. These commands will forcefully copy or move files in home & usr directory. So, before doing that, take a look inside the repo directories, and backup your existing config files (like .vimrc, .zshrc, .gitconfig, etc).

VNC Server Now, Let's configure the vnc server for graphical output. Run -

vncserver -localhost

At first time, you will be prompted for setting up passwords -

You will require a password to access your desktops.

Password:
Verify:
Would you like to enter a view-only password (y/n)? n

Note that passwords are not visible when you are typing them and maximal password length is 8 characters.
If everything is okay, you will see this message -

New 'localhost:1 ()' desktop is localhost:1

Creating default startup script /data/data/com.termux/files/home/.vnc/xstartup
Creating default config /data/data/com.termux/files/home/.vnc/config
Starting applications specified in /data/data/com.termux/files/home/.vnc/xstartup
Log file is /data/data/com.termux/files/home/.vnc/localhost:1.log

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

export DISPLAY=":1"

You may even put this variable to your bashrc or profile so you don't have to always set it manually unless display address will be changed.

Now You can start the vnc server by,

vncserver

And to stop the server, run -

vncserver -kill :1

VNC Client Now you need a vnc client app to connect to server. I'm using this Android VNC client: VNC Viewer (developed by RealVNC Limited). You can use TigerVNC if you're trying to connect to server by a computer (Windows or Linux).

Determine port number on which VNC server listens. It can be calculated like this: 5900 + {display number}. So for display 'localhost:1' the port will be 5901.

Now open the VNC Viewer application and create a new connection with the following information (assuming that VNC port is 5901) -

Address:
127.0.0.1:5901

Name:
Termux

Now launch it. You will be prompted for password that you entered on first launch of 'vncserver'. And because you've copy pasted everthing, you'll be headed to this desktop -

Well, That's it. You've successfully installed a beautiful graphical desktop on termux. Hurray!!!

Screenshots

Well, Here are some ideas or things you can do with termux and how you can make doing these stuff easy with a graphical desktop. And FYI, I'm not doing anything illegal or sponsoring any kind of Hacking and Cracking. Termux is a powerful tool, use it with responsibilities.
