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
Software consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications.
The history of software is closely tied to the development of digital computers in the mid-20th cen ...
