awesome

highly configurable X window manager

awesome manages windows dynamically in floating or tiled layouts. It is primarily targeted at power users, developers, and all those dealing with everyday computing tasks and looking for fine-grained control over their graphical environment. It is highly extensible and scriptable via the Lua programming language, providing an easy-to-use and very well documented API to configure its behavior. awesome uses tags instead of workspaces, which gives better flexibility in displaying windows, and can be entirely keyboard-driven, not needing a mouse. It also supports multi-headed configurations; uses XCB instead of Xlib for better performance; implements many freedesktop standards; and can be controlled over D-Bus from awesome-client.
