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.

xcur2png is a program decomposes an X cursor into a set of PNG images and a configuration file reusable by xcursorgen.

xf86-video-voodoo is a Voodoo video driver for the Xorg X server.

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

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.

gccmakedep is a deprecated program which calls gcc -M to output Makefile rules describing the dependencies of each source file, so that Make knows which object files must be recompiled when a dependency has changed.

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

Xorg font encoding library.

xf86-video-vesa is a generic VESA video 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-errors module provides a utility library that gives human readable names to error codes, event codes, and also to major and minor numbers.

Xorg xfree86-type1 font.

Library for the X Video Extension to the X11 protocol.

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

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

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

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.

XFree86 Video Mode Extension defines a protocol for dynamically configuring modelines and gamma.

Xpra is a persistent remote display server and client for forwarding applications and desktop screens. It gives you remote access to individual applications or full desktops. On X11, it is also known as ``screen for X11'': it allows you to run programs, usually on a remote host, direct their display to your local machine, and then to disconnect from these programs and reconnect from the same or another machine, without losing any state. It can also be used to forward full desktops from X11 servers, Windows, or macOS.

X11::Protocol is a client-side interface to the X11 Protocol, allowing perl programs to display windows and graphics on X11 servers.

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

Present Extension provides a way for applications to update their window contents from a pixmap in a well defined fashion, synchronizing with the display refresh and potentially using a more efficient mechanism than copying the contents of the source pixmap.

xf86-video-i128 is an I128 (Imagine 128) video driver for the Xorg X server.

XKB event daemon listens for the specified XKB events and executes requested commands if they occur.

xf86-video-savage is an S3 Savage video driver for the Xorg X server.
