Openbox works with your applications, and makes your desktop easier to manage. This is because the approach to its development was the opposite of what seems to be the general case for window managers. Openbox was written first to comply with standards and to work properly. Only when that was in place did the team turn to the visual interface.

Openbox is fully functional as a stand-alone working environment, or can be used as a drop-in replacement for the default window manager in the GNOME or KDE desktop environments.

Openbox 3 is a completely new breed of window manager. It is not based upon any existing code base, although the visual appearance has been based upon that of Blackbox. Openbox 2 was based on the Blackbox 0.65.0 codebase.

Some of the things to look for in Openbox are:

ICCCM and EWMH compliance!
Very fast
Chainable key bindings
Customizable mouse actions
Window resistance
Multi-head Xinerama support!
Pipe menus

To fix this problem, we can install more using the command below.

This command might take some time to finish depending on your machine internet connection.

sudo apt -y install openbox
