Open Termux and ensure your repositories are up to date before beginning the installation process.
Execute the command to install Ubuntu 24.04 in Termux. Use the command 'pkg install proot-distro' followed by 'proot-distro install ubuntu'.
After installation, log into the Ubuntu environment to proceed with desktop environment setup.
For a lightweight desktop environment, install LXQT. Update repositories first, then install LXQT and VNC server to access the desktop remotely.
Start the VNC server, create a password, and note the port number. Use a VNC viewer to connect to localhost with the specified port.
To enable sound, install X11 repository and PulseAudio. Edit configuration files and restart the environment.
For a more customizable desktop, install XFCE. Choose LightDM as the display manager and set up VNC for remote access.
Install the default GNOME desktop environment. Configure X startup and VNC server to access the desktop.
For users with more powerful devices, install the KDE desktop environment. Note that it is resource-intensive and may run slowly on low-spec devices.
