Fonts Extension contains header files and documentation for the fonts protocol.

libxcb provides an interface to the X Window System protocol, which replaces the current Xlib interface. It has several advantages over Xlib, including:

- size: small, simple library, and lower memory footprint;

- latency hiding: batch several requests and wait for the replies later;

- direct protocol access: interface and protocol correspond exactly;

- proven thread support: transparently access XCB from multiple threads;

- easy extension implementation: interfaces auto-generated from XML-XCB.

Rendering Extension defines a protocol for a digital image composition as the foundation of a new rendering model within the X Window System.

Xorg screen-cyrillic fonts.

Setxkbmap is an X11 client to change the keymaps in the X server for a specified keyboard to use the layout determined by the options listed on the command line.

Xorg misc-ethiopic fonts.

Xwd is used to store window images in a specially formatted dump file. This file can then be read by various other X utilities for redisplay, printing, editing, formatting, archiving, image processing, etc. The target window is selected by clicking the pointer in the desired window. The keyboard bell is rung once at the beginning of the dump and twice when the dump is completed.

Xorg font encoding files.

Composite Extension contains header files and documentation for the damage protocol.

X11::Protocol is a client-side interface to the X11 Protocol, allowing perl programs to display windows and graphics on X11 servers.

libxcvt is a library providing a standalone version of the X server implementation of the VESA Coordinated Video Timings (CVT) standard timing modelines generator. libxcvt also provides a standalone version of the command line tool cvt copied from the Xorg implementation and is meant to be a direct replacement to the version provided by the Xorg server.

libXtst provides the Xlib-based client API for the XTEST & RECORD extensions.

The XTEST extension is a minimal set of client and server extensions required to completely test the X11 server with no user intervention. This extension is not intended to support general journaling and playback of user actions.

The RECORD extension supports the recording and reporting of all core X protocol and arbitrary X extension protocol.

Xaw is the X 3D Athena Widget Set based on the X Toolkit Intrinsics (Xt) Library.

XRDB is used to get or set the contents of the RESOURCE_MANAGER property on the root window of screen 0, or the SCREEN_RESOURCES property on the root window of any or all screens, or everything combined. You would normally run this program from your X startup file.

Xorg font package creation/installation utilities.

BDFtoPCF is a font compiler for the X server and font server. It converts X font from Bitmap Distribution Format to Portable Compiled Format which can be read by any architecture.

This package provides a default set of cursor themes for the Xorg X server: handhelds, redglass and whiteglass.

xkbcomp keymap compiler converts a description of an XKB keymap into one of several output formats. The most common use for xkbcomp is to create a compiled keymap file (.xkm extension) which can be read directly by XKB- capable X servers or utilities.

X Keyboard (XKB) Extension essentially replaces the core protocol definition of keyboard. The extension makes possible to clearly and explicitly specify most aspects of keyboard behaviour on per-key basis and to more closely track the logical and physical state of the keyboard. It also includes a number of keyboard controls designed to make keyboards more accessible to people with physical impairments.

EGLExternalPlatform is an specification of the EGL External Platform interface for writing EGL platforms and their interactions with modern window systems on top of existing low-level EGL platform implementations. This keeps window system implementation specifics out of EGL drivers by using application-facing EGL functions.

This package provides the Xorg X server itself. The X server accepts requests from client programs to create windows, which are (normally rectangular) 'virtual screens' that the client program can draw into.

Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.

The XCB util modules provides a number of libraries which sit on top of libxcb, the core X protocol library, and some of the extension libraries. These experimental libraries provide convenience functions and interfaces which make the raw X protocol more usable. Some of the libraries also provide client-side code which is not strictly part of the X protocol but which has traditionally been provided by Xlib.

The XCB util-wm module provides the following libraries:

- ewmh: Both client and window-manager helpers for EWMH.

- icccm: Both client and window-manager helpers for ICCCM.

SMProxy allows X applications that do not support X11R6 session management to participate in an X11R6 session.

Library for the XFixes Extension to the X11 protocol.

Video Extension provides a protocol for a video output mechanism, mainly to rescale video playback in the video controller hardware.
