Window Managers

Window managers (WMs) are X clients that provide the border around a window. The window manager controls the appearance of an application and how it is managed: typically the border, titlebar, size, and ability to resize a window are handled by a wm. Many window managers provide other functionality such as places to stick dockapps, menus to configure the WM and other useful things.

Window managers generally do not provide extras like desktop icons, which are commonly seen in desktop environments (though it is possible to add icons in a WM with another program).

Because of the lack of extras, WMs are much lighter on system resources.

Types

1. Stacking (aka floating)

Provides the traditional desktop metaphor used in commercial operating systems like Windows and OS X. Windows act like pieces of paper on a desk, and can be stacked on top of each other.

2. Tiling

These "tile" the windows side-by-side so that none are overlapping. They usually make very extensive use of key-bindings and have less (or no) reliance on the mouse. Tiling window managers may be manual, offer predefined layouts, or both.

3. Dynamic

A type that can dynamically switch between tiling or floating window layout.
