Specialised types of window managers

Specialised types of window managers
Several specialised types of window manager exist.

Virtual window managers
A virtual window manager is a window manager that uses virtual screens, whose resolution can be higher than the resolution of one's monitor/display adaptor. This environment is very useful when one wishes to have a large number of windows open at the same time. A number of virtual window managers have been made, including FVWM, Tvtwm, HaZe and others.

Tiling window managers
A tiling window manager is a window manager with an organization of the screen into mutually non-overlapping frames (hence the name tiling), as opposed to the traditional approach of coordinate-based stacking of objects (windows) that tries to emulate the desk paradigm.

The first approach to this new window manager model was larswm followed later by Ion; other window managers soon followed.
