Twm is a window manager for the X Window System. It provides titlebars, shaped windows, several forms of icon management, user-defined macro functions, click-to-type and pointer-driven keyboard focus, and user-specified key and pointer button bindings.

XFontSel provides a simple way to display the X11 core protocol fonts known to your X server, examine samples of each, and retrieve the X Logical Font Description (XLFD) full name for a font.

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.

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.

This package provides types which mirror the structures used in the XCB code generation XML files and parses these XML files into Haskell data structures.

transset is a simple program for X servers supporting the XFIXES, DAMAGE, and COMPOSITE extensions. It lets the user set the transparency on a window.

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.

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

XPr takes as input a window dump file produced by xwd and formats it for output on various types of printers.

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.

TigerVNC implements a VNC client and server. VNC is a remote display system that lets you view and interact with a virtual desktop environment running on another computer on the network. Client and server may be running on different operating systems and architectures.

TigerVNC uses a variant of Tight encoding that is greatly accelerated by the use of the libjpeg-turbo JPEG codec and performs fast enough to run even 3D or video applications. It also provides extensions for advanced authentication methods and TLS encryption.

This package installs the VNC server. Permitted users can log into a graphical session on the machine where the server is running, using a VNC client such as the tigervnc-client package.

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

SessReg is a simple program for managing utmp/wtmp entries for X sessions. It was originally written for use with xdm, but may also be used with other display managers such as gdm or kdm.

ICEAuth program is used to edit and display the authorization information used in connecting with ICE (Inter-Client Exchange). It operates very much like the xauth program for X11 connection authentication records.

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.

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

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

xkeyboard-config provides a database for X Keyboard (XKB) Extension. There are five components that define a complete keyboard mapping: symbols, geometry, keycodes, compat, and types; these five components can be combined together using the rules component of this database.

Xorg XKB file handling library.

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.

This package provides a default set of cursor themes for the Xorg X server: handhelds, redglass and whiteglass.

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

libxcb provides an interface to the X Window System protocol, which replaces the current Xlib interface. It has several advantages over Xlib, including:

- size: small, simple library, and lower memory footprint;

- latency hiding: batch several requests and wait for the replies later;

- direct protocol access: interface and protocol correspond exactly;

- proven thread support: transparently access XCB from multiple threads;

- easy extension implementation: interfaces auto-generated from XML-XCB.
