What is Xephyr?

Xephyr is a kdrive based X Server which targets a window on a host X Server as its framebuffer. Unlike Xnest it supports modern X extensions ( even if host server doesn't ) such as Composite, Damage, randr etc (no GLX support now). It uses SHM Images and shadow framebuffer updates to provide good performance. It also has a visual debugging mode for observing screen updates.

Possible uses include;

Xnest replacement - Window manager, Composite 'gadget', etc development tool. Toolkit debugging - rendundant toolkit paints can be observered easily via the debugging mode. X Server internals development - develop without the need for an extra machine / display. Multiterminal with Xephyr - configuration is a single computer which supports multiple users at the same time
