Xorg

Xorg is an open source implementation of the X Window System.

Installation
There are many ways to get the X server in Gentoo, however a common method is to emerge one of the two packages:


 * - Installs the necessary components for a minimally operational X server.
 * - Installs a large Xorg software suite.

As seen from the descriptions above, those who desire a more minimal X server implementation should choose the first package.

The X USE flag
Many packages can be built with optional x11 support by activating the global X USE flag (if not already activated by profile selection).
