X11

X11 is an Open Source version of the X Window System that supports many UNIX® and UNIX-like operating systems on a variety of platforms. X11 is similar to general desktop platforms, with weak GPU performance problems. To run it, simply by typing Xorg.

Xorg is a full featured X server and supports several mechanisms for supplying/obtaining configuration and run-time parameters: command line options, environment variables, the xorg.conf configuration files, auto-detection, and fallback defaults. Typically we uses a configuration file called xorg.conf and configuration files with the suffix .conf in a directory called xorg.conf.d for its initial setup.
