Xorg Core X11 protocol client library.

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-errors module provides a utility library that gives human readable names to error codes, event codes, and also to major and minor numbers.

Xpra is a persistent remote display server and client for forwarding applications and desktop screens. It gives you remote access to individual applications or full desktops. On X11, it is also known as ``screen for X11'': it allows you to run programs, usually on a remote host, direct their display to your local machine, and then to disconnect from these programs and reconnect from the same or another machine, without losing any state. It can also be used to forward full desktops from X11 servers, Windows, or macOS.

The XCB util-renderutil module provides the following library:

- renderutil: Convenience functions for the Render extension.

ICEAuth program is used to edit and display the authorization information used in connecting with ICE (Inter-Client Exchange). It operates very much like the xauth program for X11 connection authentication records.

XInput is used to configure and test XInput devices.

xwayland-run contains a set of small utilities revolving around running Xwayland and various Wayland compositor headless, namely:

• xwayland-run: Spawn X11 client within its own dedicated Xwayland rootful instance.

• wlheadless-run: Run Wayland client on a set of supported Wayland headless compositors.

• xwfb-run: Combination of above two tools to be used as a direct replacement for xvfb-run specifically.

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

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.

Resource Extension defines a protocol that allows a client to query the X server about its usage of various resources.

xf86-video-r128 is a video driver for the Xorg X server. This driver is intended for ATI Rage 128 based cards.

XFD (X Font Display) package provides an utility that displays a window containing the name of the font being displayed, a row of command buttons, several lines of text for displaying character metrics, and a grid containing one glyph per cell.

Xorg adobe-75dpi fonts.

Library for the Resize and Rotate Extension to the X11 protocol.

xf86-input-mouse is a mouse input driver for the Xorg X server. This driver supports four classes of mice: serial, bus and PS/2 mice, and additional mouse types supported by specific operating systems, such as USB mice.

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.

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

xf86-video-freedreno is a 2D graphics driver for the Xorg X server. It supports a variety of Adreno graphics chipsets.

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

Imake is a deprecated source code configuration and build system which has traditionally been supplied by and used to build the X Window System in X11R6 and previous releases. As of the X Window System X11R7 release, the X Window system has switched to using GNU autotools as the primary build system, and the Imake system is now deprecated, and should not be used by new software projects. Software developers are encouraged to migrate software to the GNU autotools system.

Xmu library contains miscellaneous utilities and is not part of the Xlib standard. It is intended to support clients in the Xorg distribution; vendors may choose not to distribute this library if they wish. Therefore, applications developers who depend on this library should be prepared to treat it as part of their software base when porting.

xf86-input-joystick is a joystick input driver for the Xorg X server. It is used to control the pointer with a joystick device.

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.
