The Direct Rendering Infrastructure, also known as the DRI, is a framework for allowing direct access to graphics hardware under the X Window System in a safe and efficient manner. It includes changes to the X server, to several client libraries, and to the kernel (DRM, Direct Rendering Manager). The most important use for the DRI is to create fast OpenGL implementations providing hardware acceleration for Mesa. Several 3D accelerated drivers have been written to the DRI specification, including drivers for chipsets produced by 3DFX, AMD (formerly ATI), Intel and Matrox.

screen-message is a tool for displaying text on your screen. It will make the text as large as possible and display it with black color on a white background (colors are configurable on the commandline).

The xvkbd displays a drawing of a computer keyboard in a window on the screen. Clicking on its keys sends the corresponding keystroke(s) to other X clients, as if typed on a physical keyboard.

This is useful for systems without keyboard hardware but with a pointing device, such as kiosk terminals or handheld devices with touch screens.

A limited number of keyboard layouts are available, as is dictionary completion. You can also use xvkbd to send a series of predetermined keystrokes from the command line, without displaying a keyboard at all.

ARandR is designed to provide a simple visual front end for the X11 resize-and-rotate (RandR) extension. Relative monitor positions are shown graphically and can be changed in a drag-and-drop way. Configurations are saved as executable shell scripts which can be loaded without using this program.

Xdpyprobe is a tiny C program whose only purpose is to probe a connectivity of the X server running on a particular DISPLAY.

XSel is a command-line program for getting and setting the contents of the X selection and/or clipboard. Normally this is only accessible by manually highlighting information and pasting it with the middle mouse button.

XSel reads from standard input and writes to standard output by default, but can also follow a growing file, display contents, delete entries and more.

xiccd provides color profile support for desktop environments other than GNOME and KDE. It does the following tasks:

• Enumerates displays and register them in colord.

• Creates default ICC profiles based on EDID data.

• Applies ICC profiles provided by colord.

• Maintains user's private ICC storage directory.

Wob, or Wayland Overlay Bar, is a lightweight overlay volume, backlight, progress, or anything bar for Wayland.

xsettingsd is a lightweight daemon that provides settings to Xorg applications via the XSETTINGS specification. It is used for defining font and theme settings when a complete desktop environment (GNOME, KDE) is not running. With a simple .xsettingsd configuration file one can avoid configuring visual settings in different UI toolkits separately.

xwhite is a command line tool for adjusting the colour balance of screen. It is based on xrandr's gamma correction and brightness adjustment. As such, it can only be used for X displays and not Wayland displays. It is typically used for tuning the color balance and color temperature. It has a similar function as redshift -P -g R:G:B -O temperature, but xwhite is more flexible in that it does not keep the white color fixed, suitable for setting the white color to an arbitrary balanced color.

XForms is a graphical user interface toolkit for X based on the X11 Xlib library. It allows you to create windows, containing all kinds of widgets (buttons, sliders, browsers, menus etc.) with a few lines of code and then attach actions to the widgets, i.e., have some function called when a button is pressed. To make this even easier XForms comes with a program called fdesign that allows you to design a GUI for a program directly on the screen and which then writes out the necessary C code for it.

Rofi is a minimalist application launcher. It memorizes which applications you regularly use and also allows you to search for an application by name.

xcalib is a tiny tool to load the content of vcgt-Tags in ICC profiles to the video card's gamma ramp. It does work with most video card drivers except the generic VESA driver. Alter brightness, contrast, RGB, and invert colors on a specific display/screen.

Start clipmenud, then run clipmenu to select something to put on the clipboard.

When clipmenud detects changes to the clipboard contents, it writes them out to the cache directory. clipmenu reads the cache directory to find all available clips and launches dmenu (or rofi, depending on the value of CM_LAUNCHER) to let the user select a clip. After selection, the clip is put onto the PRIMARY and CLIPBOARD X selections.

ydotool is a Linux command-line tool that simulates keyboard input, mouse actions, etc. programmatically or manually.

xss-lock listens to X signals to fire up a user-defined screensaver. In effect this automatically locks the screen when closing a laptop lid or after a period of user inactivity (as set with xset s TIMEOUT). The notifier command, if specified, is executed first. Additionally, xss-lock uses the inhibition logic to lock the screen before the system goes to sleep.

Hyprpaper is a blazing fast wallpaper utility for Hyprland with the ability to dynamically change wallpapers through sockets. It will work on all wlroots-based compositors, though.

This package provides an accelerated X server library for i.MX6.

Xclip is a command line interface to the X11 clipboard. It can also be used for copying files, as an alternative to sftp/scp, thus avoiding password prompts when X11 forwarding has already been setup.

Wl-clipboard is a set of command-line copy/paste utilities for Wayland.

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.

XCB util-xrm module provides the following libraries:

- xrm: utility functions for the X resource manager.

maim (Make Image) is a tool that takes screenshots of your desktop and saves it in any format. Along with a full screen, it allows you to capture a predefined region or a particular window. Also, it makes it possible to include cursor in the resulting image.

Apply the given action to the given windows. If no window IDs and no options are given, the action applies to the focused window.

Provides bindings to libxdo for manipulating X11 via simulated input. (Note that this is mostly a legacy library; you may wish to look at python-xdo for newer bindings.)
