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 is a fork with added support for Wayland using the wlr-gamma-control protocol.

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.

Rxvt-unicode (urxvt) is a colour vt102 terminal emulator intended as an xterm replacement for users who do not require features such as Tektronix 4014 emulation and toolkit-style configurability. It supports unicode, XFT and may be extended with Perl plugins. It also comes with a client/daemon pair that lets you open any number of terminal windows from within a single process.

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.

Darkman is a framework for dark-mode and light-mode transitions on Unix-like desktops.

This package provides a wlroots-compatible Wayland color picker.

xkb-switch is a C++ program that queries and changes the XKB layout state.

Gammastep automatically adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working in front of the screen at night.

Tofi is a Dmenu and Rofi replacement for wlroots-based Wayland compositors such as Sway.

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.

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.

nxbelld is a tiny utility to aid people who either don't like the default PC speaker beep, or use a sound driver that doesn't have support for the PC speaker. The utility performs a given action every time the X bell is rung. The actions nxbelld can currently perform include running a specified program, emulating the PC speaker beep using the sound card (default), or playing a PCM encoded WAVE file.

Dzen is a general purpose messaging, notification and menuing program for X11. It was designed to be fast, tiny and scriptable in any language.

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.

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.

This package provides a wrapper script around x11-clipboard to use it as a clipboard on X11 also. It also contains helper scripts for xclip and xsel to assist with the transition.

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.

This package provides a library for programmatically controlling Xorg windows using Python. The library relies on the wmctrl to do so.

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.

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.

Xautomation can control X from the command line for scripts, and do visual scraping to find things on the screen. The control interface allows mouse movement, clicking, button up/down, key up/down, etc, and uses the XTest extension so you don't have the annoying problems that xse has when apps ignore sent events. The visgrep program can find images inside of images and reports the coordinates, allowing programs to find buttons, etc, on the screen to click on.

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.

xssproxy implements the org.freedesktop.ScreenSaver D-Bus interface described in the Idle Inhibition Service Draft by the freedesktop.org developers. The inhibition of the screensaver is then controlled using the XScreenSaverSuspend function from the Xss (X11 Screen Saver extension) library.

Xeyes is a demo program for x.org. It shows eyes following the mouse.
