xmonad is a tiling window manager for X. Windows are arranged automatically to tile the screen without gaps or overlap, maximising screen use. All features of the window manager are accessible from the keyboard: a mouse is strictly optional. xmonad is written and extensible in Haskell. Custom layout algorithms, and other extensions, may be written by the user in config files. Layouts are applied dynamically, and different layouts may be used on each workspace. Xinerama is fully supported, allowing windows to be tiled on several screens. This is a meta-package that installs xmonad-basic and ghc-xmonad-contrib-devel, allowing xmonad to be customized with "~/.xmonad/xmonad.hs". To use xmonad with GNOME/MATE, please install xmonad-mate.
