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

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.

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.

This package provides a Xlib-based library for the X Present Extension.

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.

Xorg Display Manager Control Protocol library.

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

Font Service client library is used by clients of X Font Servers (xfs), such as xfsinfo, fslsfonts, and the X servers themselves.

xbitmaps provides basic bitmaps (little pictures) used by some legacy X clients.

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.

Xbacklight is used to adjust the backlight brightness where supported. It uses the RandR extension to find all outputs on the X server supporting backlight brightness control and changes them all in the same way.

Xorg Session Management library.

Uim is a multilingual input method library and environment. It provides a simple, easily extensible and high code-quality input method development platform, and useful input method environment for users of desktop and embedded platforms.

Rendering Extension defines a protocol for a digital image composition as the foundation of a new rendering model within the X Window System.

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

xf86-input-libinput is an input driver for the Xorg X server based on libinput. It is a thin wrapper around libinput, so while it does provide all features that libinput supports it does little beyond.

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.

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.

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-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 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.

xf86-input-mouse is a mouse input driver for the Xorg X server. This driver supports four classes of mice: serial, bus and PS/2 mice, and additional mouse types supported by specific operating systems, such as USB mice.

Direct Rendering Infrastructure 3 Extension provides mechanisms to translate between direct rendered buffers and X pixmaps. When combined with the Present extension, a complete direct rendering solution for OpenGL is provided.

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