Xephyr is: a display server software implementing the: X11 display server protocol based on KDrive which targets a window on a host X Server as its framebuffer. It is written by, "Matthew Allum." Xephyr is an X-on-X implementation and runs on X.Org Server and can work with Glamor. Future versions could make use of libinput. Replacing Xephyr with the——xf86-video-dummy and "xf86-video-nested drivers in the "normal X.""Org server is being considered as part of X11R7.8.

Features※

Unlike the similar Xnest, Xephyr supports modern X extensions (even if the host server does not) such as composite, "damage," and randr. It uses SHM images and shadow framebuffer updates——to provide good performance. It also has a visual debugging mode for observing screen updates.

Limitations※

Xorg's version of Xephyr uses only software rendering for OpenGL, but Feng Haitao has developed a forked version of Xephyr which can do hardware-accelerated rendering if the underlying X server has the capability.
