• Fluxbox is a lightweight window manager for the X Windowing System.
• Fluxbox provides configurable window decorations, a root menu to launch applications and a toolbar that shows the current workspace name, a set of application names and the current time. There is also a workspace menu which allows you to add or remove workspaces. The `slit' can be used to dock small applications, e.g. most of the bbtools can use slit.
• Fluxbox can iconify windows to the toolbar, in addition to adding the window to the Icons submenu of the workspace menu. One click and they reappear. A double-click on the titlebar of the window will shade it, i.e. the window will disappear leaving only the titlebar visible.
• Fluxbox is a stacking window manager for the X Window System, which started as a fork of Blackbox 0.61.1 in 2001, with the same aim to be lightweight. Its user interface has only a taskbar, a pop-up menu accessible by right-clicking on the desktop, and support for graphical icons. All basic configurations are controlled by text files, including the construction of menus and the mapping of key-bindings. Fluxbox has high compliance to the Extended Window Manager Hints specification.
• Fluxbox is basic in appearance, but it can show a few options for improved attractiveness: colors, gradients, borders, and several other basic appearance attributes can be specified. Recent versions support rounded corners and graphical elements. Effects managers such as xcompmgr, cairo-compmgr and transset-df (deprecated) can add true transparency to desktop elements and windows. Enhancements can also be provided by using iDesk or fbdesk, SpaceFM, PCMan File Manager or the ROX Desktop. Fluxbox also has several features Blackbox lacks, including tabbed windows and a configurable titlebar.
• Because of its small memory footprint and quick loading time, Fluxbox is popular in many Live CDs such as GParted. It was the default window manager of Damn Small Linux and antiX, but was replaced with JWM in 2007 and 2009, respectively. It is currently the default window manager of PCFluxboxOS, a remaster of PCLinuxOS, and of Linux Mint Fluxbox CE. Fluxbuntu, an Ubuntu derivative with lightweight applications, was released in October 2007; it is also a featured window manager on antiX. On December 12, 2019, MX Linux released MX-fluxbox as a fully integrated overlay.
• Fluxbox uses its own graphics class to render its images on the fly. By using style files, you can determine in great detail how your desktop looks. Fluxbox styles are compatible with those of Blackbox 0.65 or earlier versions, so users migrating can still use their favourite themes.
• Fluxbox supports the majority of the Extended Window Manager Hints (EWMH) specification, as well as numerous other Window Hinting standards. This allows all compliant window managers to provide a common interface to standard features used by applications and desktop utilities.

To get the fluxbox source you can visit the fluxbox home page. Make sure you are downloading the development version. If you are having trouble downloading the stable version, you can visit the troubleshoot page. Many people often want the 'stable' version but the fluxbox development version is very stable and is the only version which is being worked on so finding support for problems you run into with the 'stable' version, such as build problems, will not be supported ('stable' is over 3 years old..). If you do not want to build your version from source you need to download a package for your distro. Take a look at the packages page to find a package for your distro.
