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. [1] Future versions could make use of libinput.[ citation needed ] 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.
