Library for the Resize and Rotate Extension to the X11 protocol.

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.

This library provides weak aliases for pthread functions not provided in libc or otherwise available by default. Libraries like libxcb rely on pthread stubs to use pthreads optionally, becoming thread-safe when linked to libpthread, while avoiding any performance hit when running single-threaded.

Xorg XToolkit Intrinsics library.

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.

Xorg misc-cyrillic fonts.

xf86-video-r128 is a video driver for the Xorg X server. This driver is intended for ATI Rage 128 based cards.

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

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.

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.

SMProxy allows X applications that do not support X11R6 session management to participate in an X11R6 session.

Library for common extensions to the X11 protocol.

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.

Xtrans is a library of code that is shared among various X packages to handle network protocol transport in a modular fashion, allowing a single place to add new transport types. It is used by the X server, libX11, libICE, the X font server, and related components.

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.

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

Xorg sun-misc fonts.

Xorg adobe-100dpi fonts.

xlsfonts lists fonts available from an X server via the X11 core protocol.

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

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

X Keyboard (XKB) Extension defines a protocol to provide a number of new capabilities and controls for text keyboards.

Xorg Generic PCI access library.

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.
