Xdotool lets you simulate keyboard input and mouse activity, move and resize windows, etc. It does this using X11's XTEST extension and other Xlib functions. Additionally, you can search for windows and move, resize, hide, and modify window properties like the title. If your window manager supports it, you can use xdotool to switch desktops, move windows between desktops, and change the number of desktops.

kbdd is a simple keyboard layout switching program, which is designed to run in an X11 session and remember keyboard layouts on a per-window basis. That can be very handy for a user of a non-US keyboard who does not want to jump through layouts back and forth while typing in terminals (mostly in a latin alphabet) and some kind of chat (in native language).

kbdd also supports D-Bus signals, which makes it possible to create layout indicator widgets.

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.

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

This package includes a variety of xkb keyboard options including ergonomic layouts and the 'extend' layer for easy access to modifiers and function keys.

Bemoji is an emoji picker for dmenu-like launchers (e.g. bemenu, wofi, rofi, fuzzel, etc.) It will remember your favorite emojis and give you quick access to them via a separately installed clipboard tool (e.g. wl-copy, xclip, etc.), or a typing tool (wtype, xdotool, etc.), or via standard output.

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.

wl-color-picker is a script that provides color picker for Wayland and wlroots by leveraging grim and slurp.

Wlsunset adjusts gamma based on day-night cycles on Wayland compositors that support wlr-gamma-control-unstable-v1. It is also known as a blue light filter or night light.

This is a small utility to provide a blue light filter for your system. This method is preferred to screen shaders as it will not be captured via recording / screenshots.

hyprsunset also provides a gamma filter, which can be used to adjust perceived display brightness on monitors that do not support software control, or to reduce percieved brightness below the monitor's minimum.

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.

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.

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.

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.

autocutsel tracks changes in the server's cutbuffer and clipboard selection. When the clipboard is changed, it updates the cutbuffer. When the cutbuffer is changed, it owns the clipboard selection. The cutbuffer and clipboard selection are always synchronized.

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).

dex, DesktopEntry Execution, is a program to generate and execute .desktop files of the Application type. It is also an autostarter compliant with the XDG autostart specification.

This package provides a wlroots-compatible Wayland color picker.

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

Pyperclip is a clipboard module for Python, handling copy/pasting from the X11 clipboard

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.

Redshift adjusts the color temperature according to the position of the sun. A different color temperature is set during night and daytime. During twilight and early morning, the color temperature transitions smoothly from night to daytime temperature to allow your eyes to slowly adapt. At night the color temperature should be set to match the lamps in your room.

This library implements cross-platform clipboard utilities supporting both binary and text data.

xkblayout is a CLI application to generate templates for a new XKB layout, either in the user's home directory or the system directory.
