Blackbox is an open source and freely distributed software project that has been designed from the ground up to act as a standalone or integrated window manager in the style of the more popular Openbox and Fluxbox projects. It is a lightweight and low on resources WM (Window Manager) that has no annoying library dependencies.
It’s similar to Fluxbox and Openbox
As mentioned, Blackbox is similar to Fluxbox and Openbox, in both functionality and appearance. This means that it can be used on top of an a desktop environment or as a standalone window manager on top of X11. It comprises of a single panel that can be placed either on top or on the bottom edge of the screen, allowing users to cycle between virtual workspaces, interact with running programs, as well as to access essential system functions. It features a right-click context menu that acts as a Main Menu.
Desktop environment compatibility
The Blackbox window manager is fully compatible with your current desktop environment, as it can be easily used as a drop-in replacement for any other open-source window manager. While it has been successfully tested with GNOME and KDE desktops, it should also work well with Xfce, LXDE, Cinnamon, MATE, and other DEs.
Supported operating systems
Officially supported GNU/Linux operating systems include Debian, Fedora, Arch Linux, Gentoo and Slackware. However, Blackbox is also known to work well on the Mac OS X operating system. Both 64-bit and 32-bit architectures are supported at this time.
Under the hood and availability
A quick look under the hood will show us that Blackbox is written entirely in the C++ programming language and requires only a functional X Window System (X11). It is available for download only as a universal source tarball, but it can be easily installed from the default software repositories of many GNU/Linux distributions.
