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.

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

Xorg misc-ethiopic fonts.

Library for the XFree86 Video Mode Extension Extension to the X11 protocol.

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

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

Xorg font encoding library.

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

XGamma is used to query and alter the gamma correction of a monitor via the X video mode extension.

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.

Xorg xfree86-type1 font.

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.

xf86-video-vesa is a generic VESA video driver for the Xorg X server.

xf86-video-mach64 is a video driver for the Xorg X server. This driver is intended for all ATI video adapters based on the Mach64 series or older chipsets, providing maximum video function within hardware limitations. The driver is also intended to optionally provide the same level of support for generic VGA or 8514/A adapters.

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.

Xorg Display Manager Control Protocol library.

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

libxcvt is a library providing a standalone version of the X server implementation of the VESA Coordinated Video Timings (CVT) standard timing modelines generator. libxcvt also provides a standalone version of the command line tool cvt copied from the Xorg implementation and is meant to be a direct replacement to the version provided by the Xorg server.

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.

Client library for the Composite extension to the X11 protocol.

Xorg font package creation/installation utilities.

XEv creates a window and then asks the X server to send it X11 events whenever anything happens to the window (such as it being moved, resized, typed in, clicked in, etc.). You can also attach it to an existing window. It is useful for seeing what causes events to occur and to display the information that they contain; it is essentially a debugging and development tool, and should not be needed in normal usage.

Editres is a tool that allows users and application developers to view the full widget hierarchy of any X Toolkit application that speaks the Editres protocol. In addition, editres will help the user construct resource specifications, allow the user to apply the resource to the application and view the results dynamically. Once the user is happy with a resource specification editres will append the resource string to the user's X Resources file.
