This library provides an interface to shared-memory fences for synchronization between the X server and direct-rendering clients.

Resize and Rotate Extension defines a protocol for clients to dynamically change X screens, so as to resize, rotate and reflect the root window of a screen.

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.

console-setup provides the console with the same keyboard configuration scheme that the X Window System has. In particular, the ckbcomp program compiles an XKB keyboard description to a keymap suitable for loadkeys or kbdcontrol. As a result, there is no need to duplicate or change the console keyboard files just to make simple customizations.

Besides the keyboard, the package also configures the font on the console. It includes a rich collection of fonts and supports several languages that would otherwise be unsupported on the console (such as Armenian, Georgian, Lao, and Thai).

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.

libXau provides an authorization library for individual access to an X Window System display.

Xorg XKB file handling library.

XFontSel provides a simple way to display the X11 core protocol fonts known to your X server, examine samples of each, and retrieve the X Logical Font Description (XLFD) full name for a font.

Uim is a multilingual input method library and environment. It provides a simple, easily extensible and high code-quality input method development platform, and useful input method environment for users of desktop and embedded platforms.

The xvfb-run wrapper simplifies running commands and scripts within a virtual X server environment. It sets up an X authority file or uses an existing user-specified one, writes a cookie to it, and then starts the Xvfb X server as a background process. It also takes care of killing the server and cleaning up before returning the exit status of the command.

MkFontScale creates the fonts.scale and fonts.dir index files used by the legacy X11 font system.

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

XLsClients is used to list information about the client programs running on X server.

X Resource extension library.

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.

XFree86 Direct Graphic Access Extension defines a protocol for direct linear framebuffer access.

Xorg font encoding library.

Present Extension provides a way for applications to update their window contents from a pixmap in a well defined fashion, synchronizing with the display refresh and potentially using a more efficient mechanism than copying the contents of the source pixmap.

Xbacklight is used to adjust the backlight brightness where supported. It uses the RandR extension to find all outputs on the X server supporting backlight brightness control and changes them all in the same way.

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-keysyms module provides the following library:

- keysyms: Standard X key constants and conversion to/from keycodes.

Library for the XInput Extension to the X11 protocol.

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.

Xorg Generic PCI access library.

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