The XCB util module 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 module provides the following libraries:

- aux: Convenient access to connection setup and some core requests.

- atom: Standard core X atom constants and atom caching.

- event: Some utilities that have little to do with events any more.

xf86-input-libinput is an input driver for the Xorg X server based on libinput. It is a thin wrapper around libinput, so while it does provide all features that libinput supports it does little beyond.

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

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.

xf86-video-geode is an Xorg X server video driver for the AMD Geode GX and LX processors. The GX component supports both XAA and EXA for graphics acceleration. The LX component supports EXA, including compositing. Both support Xv overlay and dynamic rotation with XRandR.

The xinit program is used to start the X Window System server and a first client program on systems that are not using a display manager such as xdm. This package also provides the startx command, which provides a user-friendly mechanism to start the X server.

xf86-video-ast is an ASpeed Technologies video driver for the Xorg X server.

The xkbprint utility visualises (``prints'') an XKB keyboard description as printable or encapsulated PostScript. It accepts any compiled keymap (.xkm) file that includes a geometry description, or can obtain one from a running X server.

libevdev is a wrapper library for evdev devices. it moves the common tasks when dealing with evdev devices into a library and provides a library interface to the callers, thus avoiding erroneous ioctls, etc.

The eventual goal is that libevdev wraps all ioctls available to evdev devices, thus making direct access unnecessary.

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 Display Manager Control Protocol library.

This package provides a Xlib-based library for the X Present Extension.

Direct Rendering Infrastructure 2 Extension defines a protocol to securely allow user applications to access the video hardware without requiring data to be passed through the X server.

Library for the XInput Extension to the X11 protocol.

XCB-Proto provides the XML-XCB protocol descriptions that libxcb uses to generate the majority of its code and API. XCB-Proto is separated from libxcb to allow reuse by other projects, such as additional language bindings, protocol dissectors, or documentation generators.

XCB-Proto also contains language-independent Python libraries that are used to parse an XML description and create objects used by Python code generators in individual language bindings.

XExtProto provides the following extensions: DOUBLE-BUFFER, DPMS, Extended-Visual-Information, Generic Event Extension, LBX, MIT-SHM, MIT-SUNDRY-NONSTANDARD, Multi-Buffering, SECURITY, SHAPE, SYNC, TOG-CUP, XC-APPGROUP, XTEST.

transset is a simple program for X servers supporting the XFIXES, DAMAGE, and COMPOSITE extensions. It lets the user set the transparency on a window.

xf86-input-synaptics is a touchpad driver for the Xorg X server.

xcompmgr is a sample compositing manager for X servers supporting the XFIXES, DAMAGE, RENDER, and COMPOSITE extensions. It enables basic eye-candy effects.

Hackneyed is a scalable cursor theme mildly resembling old Windows 3.x cursors. The cursors are available in white and black colors. A left-handed version of the cursors is also included.

xf86-video-SiS is a SiS video driver for the Xorg X server. This driver supports SiS chipsets of 300/315/330/340 series.

XKBUtils is a collection of small utilities for X Keyboard (XKB) extension to the X11 protocol. It includes:

- xkbbell: generate XKB bell events;

- xkbvleds: display the state of LEDs on an XKB keyboard in a window;

- xkbwatch: reports changes in the XKB keyboard state.
