Xmessage displays a message or query in a window. The user can click on a button to dismiss it or can select one of several buttons to answer a question. Xmessage can also exit after a specified time.

Virtual/offscreen frame buffer driver for the Xorg X server.

Xorg Generic PCI access library.

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

Xmodmap is used to display and edit the keyboard modifier map and keymap table that are used by client programs running on X server to convert event keycodes into keysyms. It is usually run from the user's session startup script to configure the keyboard according to personal tastes.

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.

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.

XSetRoot allows you to tailor the appearance of the root window on a display running X server.

Xorg XToolkit Intrinsics library.

Xorg winitzki-cyrillic font.

The xclock program displays the time in analog or digital form.

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.

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.

The XCB util modules 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-wm module provides the following libraries:

- ewmh: Both client and window-manager helpers for EWMH.

- icccm: Both client and window-manager helpers for ICCCM.

XWinInfo is used to print out information about windows on an X server. Various information is displayed depending on which options are selected.

Makedepend is an utility for creating dependencies in makefiles.

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.

xf86-video-qxl is a video driver for the Xorg X server. This driver is intended for the spice qxl virtio device.

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

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.

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.

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.

v86d provides a backend for kernel drivers that need to execute x86 BIOS code. The code is executed in a controlled environment and the results are passed back to the kernel via the netlink interface. v86d is required by the uvesafb Linux kernel module that provides an fbdev framebuffer when Kernel Mode Setting is unavailable. It can be a last resort when no other Xorg X server driver works.

Xorg screen-cyrillic fonts.
