+	  This variant of the X.org server is the full-blown variant,
+	  as used by desktop GNU/Linux distributions. The drivers (for
+	  input and graphics) are built separately from the X.org

+	help
+	  This variant of the X.org server is a lightweight version
+	  intended for embedded systems. The drivers (for input and
+	  graphics) are built into the server. It is generally used
+	  directly on top of the Linux framebuffer without DRM or
+	  video card specific drivers.
