XC-MISC Extension defines a protocol that provides Xlib two ways to query the server for available resource IDs.

Record Extension defines a protocol for the recording and playback of user actions in the X Window System.

Makedepend is an utility for creating dependencies in makefiles.

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

xf86-video-amdgpu is an AMD Radeon video driver for the Xorg X server.

Xorg misc-cyrillic fonts.

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

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-image module provides the following library:

- image: Port of Xlib's XImage and XShmImage functions.

Xorg sun-misc fonts.

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.

Xwayland is an X server for running X clients under Wayland.

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.

XAuth program is used to edit and display the authorization information used in connecting to the X server.

libXfont provides the core of the legacy X11 font system, handling the index files (fonts.dir, fonts.alias, fonts.scale), the various font file formats, and rasterizing them. It is used by the X servers, the X Font Server (xfs), and some font utilities (bdftopcf for instance), but should not be used by normal X11 clients. X11 clients access fonts via either the new API's in libXft, or the legacy API's in libX11.

Xorg adobe-100dpi fonts.

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

xprop is used to display and/or set window and font properties of an X server.

xf86-input-evdev is a generic input driver for the Xorg X server. This driver supports all input devices that the kernel knows about, including most mice, keyboards, tablets and touchscreens.

xwayland-satellite grants rootless Xwayland integration to any Wayland compositor implementing the xdg_wm_base interface. This is particularly useful for compositors that (understandably) do not want to go through implementing support for rootless Xwayland themselves.

This package provides the X color name database.

Xorg FreeType library connects X applications with the FreeType font rasterization library. Xft uses fontconfig to locate fonts so it has no configuration files.

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.

XKill is used to force the X server to close connections to clients. This program is very dangerous, but is useful for aborting programs that have displayed undesired windows on a user's screen.

DMX (Distributed Multihead X) extension library.
