Setroot is a lightweight X background setter with feh's syntax without its image viewing capabilities. It supports multiple monitors and can restore previously set wallpapers and options.

This package provides the headers and specification documents defining the core protocol and (many) extensions for the X Window System.

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

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.

Xdpyinfo is used to display information about an X server: the capabilities of a server, the predefined values for various parameters used in communicating between clients and the server, and the different types of screens, visuals, and X11 protocol extensions that are available.

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

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.

MkFontDir creates the fonts.dir files needed by the legacy X server core font system. The current implementation is a simple wrapper script around the mkfontscale program.

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

xf86-video-fbdev is a video driver for the Xorg X server for framebuffer device.

X11Perf is a simple performance benchmarker for the Xorg X server.

This package provides a set of autoconf macros used by the configure.ac scripts in other Xorg modular packages, and is needed to generate new versions of their configure scripts with autoconf.

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.

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.

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.

The xterm program is a terminal emulator for the X Window System. It provides DEC VT102/VT220 (VTxxx) and Tektronix 4014 compatible terminals for programs that cannot use the window system directly.

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-input-void is a null input driver for the Xorg X server.

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.

Print Extension defines a protocol for a portable, network-transparent printing system.

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

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

XLsAtoms is used to list the interned atoms defined on X server.

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