XFCE4 on Termux

In this short guide I will explain how to run Ubuntu with Xfce4 desktop environment on your Android smartphone by using Termux-X11 in an isolated environment without root privileges. With minor adjustments this guide should work for Debian too (just replace ubuntu by debian).

Note: Neither of options won't support systemd. Moreover, Firefox on Ubuntu is distributed as a snap package, which in turn does not work without systemd.

Host system

I am a user of an arm64 based Android smartphone. First of all let's install Termux application from Play Market.
