Install Blackbox Window Manager on Ubuntu Linux

Installing Blackbox Window Manager on Ubuntu
The standard Ubuntu desktop environment utilizes the Gnome window manager. However, a variety of alternative window managers are available for installation, such as KDE, Xfce, and Fluxbox. The installation of Blackbox is a straightforward procedure.
Prior to beginning, ensure that you have enabled the necessary alternate installation repositories. A terminal window should then be opened to execute the following command:
sudo apt-get install blackbox
Accessing Blackbox After Installation
Upon completion of the installation process, log out of your current session. Then, locate and click the 'Options' button situated in the bottom-left corner of the login screen.
A menu will appear, displaying all window managers currently installed on the system. From this menu, select Blackbox to proceed with logging in.
Blackbox Desktop Overview
The Blackbox desktop environment is characterized by its simplicity, bearing a strong resemblance to Fluxbox in its appearance and functionality.
A right-click on the desktop background will reveal the main menu, providing access to various system functions and settings.

The interface is intentionally minimalistic, offering a streamlined user experience.
