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

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.

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.

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

Xorg Session Management library.

WindowsWM Extension defines a protocol, used for coordination between an X11 server and the Microsoft Windows native window manager. WindowsWM is only intended to be used on Cygwin when running a rootless XWin server.

Luit is a filter that can be run between an arbitrary application and a UTF-8 terminal emulator such as xterm. It will convert application output from the locale's encoding into UTF-8, and convert terminal input from UTF-8 into the locale's encoding.

Xorg cronyx-cyrillic font.

xrandr - primitive command line interface to X11 Resize, Rotate, and Reflect (RandR) extension.

Xorg XKB file handling library.

Xorg library for the XDamage extension.

This package provides the Xorg X server itself. The X server accepts requests from client programs to create windows, which are (normally rectangular) 'virtual screens' that the client program can draw into.

Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.

xf86-video-vmware is a VMware SVGA video driver for the Xorg X server.

XFree86 Bigfont Extension contains header files and documentation for the XF86BigFontProto protocol.

XProto provides the headers and specification documents defining the X Window System Core Protocol, Version 11.

It also includes a number of headers that aren't purely protocol related, but are depended upon by many other X Window System packages to provide common definitions and porting layer.

X11::Protocol::Other contains window manager related functions for use by client programs, as per the ICCCM (Inter-Client Communication Conventions Manual) and some of the EWMH (Extended Window Manager Hints).

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

libevdev is a wrapper library for evdev devices. it moves the common tasks when dealing with evdev devices into a library and provides a library interface to the callers, thus avoiding erroneous ioctls, etc.

The eventual goal is that libevdev wraps all ioctls available to evdev devices, thus making direct access unnecessary.

Xwd is used to store window images in a specially formatted dump file. This file can then be read by various other X utilities for redisplay, printing, editing, formatting, archiving, image processing, etc. The target window is selected by clicking the pointer in the desired window. The keyboard bell is rung once at the beginning of the dump and twice when the dump is completed.

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 only the VNC client (vncviewer), the application used to connect to VNC servers such as the tigervnc-server package.

This library provides an interface to shared-memory fences for synchronization between the X server and direct-rendering clients.

xf86-video-mga is a Matrox video driver for the Xorg X server.

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.

Xorg Display Manager Control Protocol library.
