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.

If arguments are given, xtitle outputs the title of each specified window, otherwise it outputs the title of the active window. With snoop mode on, it continuously monitors the specified windows and outputs when titles change.

This is a program to help manage many of the XKB features of the X Window System. This includes such features as MouseKeys, AccessX, StickyKeys, BounceKeys, and SlowKeys. It includes a graphical program to help with MouseKeys-acceleration management.

clipnotify is a simple program that, using the XFIXES extension to X11, waits until a new selection is available and then exits.

It was primarily designed for clipmenu, to avoid polling for new selections.

clipnotify doesn't try to print anything about the contents of the selection, it just exits when it changes. This is intentional -- X11's selection API is verging on the insane, and there are plenty of others who have already lost their sanity to bring us xclip/xsel/etc. Use one of those tools to complement clipnotify.

Unclutter is a program which runs permanently in the background of an X11 session. It checks on the X11 pointer (cursor) position every few seconds, and when it finds it has not moved (and no buttons are pressed on the mouse, and the cursor is not in the root window) it creates a small sub-window as a child of the window the cursor is in. The new window installs a cursor of size 1x1 but a mask of all 0, i.e. an invisible cursor. This allows you to see all the text in an xterm or xedit, for example. The human factors crowd would agree it should make things less distracting.

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.

The xwallpaper utility allows you to set image files as your X wallpaper. JPEG, PNG, and XPM file formats are supported.

The wallpaper is also advertised to programs which support semi-transparent backgrounds.

The x-resize command detects physical display resolution changes via udev and invokes the xrandr command to reconfigure the active display resolution accordingly. It can be used to implement dynamic resize support for desktop environments that lack native support such as Xfce.

Scrot saves a screenshot of a full screen, a window or a part of the screen selected by mouse.

Xkeysnail is an X environment keyboard remapping tool, featuring high-level and flexible remapping mechanisms. It affects the low-level layers (evdev and uinput), making remapping work in almost all the places.

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

This utility for X.org uses a modifier key as another key when pressed and released on its own. The default behaviour is to generate the Escape key when Left Control is pressed and released on its own.

xftwidth is a small C program for calculating the pixel widths of displayed text using Xft fonts. It is especially useful in scripts for displaying text in graphical panels, menus, popups, and notification windows generated using dzen. These scripts are often used in conjunction with minimalistic tiling window managers such as herbstluftwm and bspwm.

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

Tint2 is a simple task bar made for modern X window managers. It was specifically made for Openbox but it should also work with other window managers (GNOME, KDE, XFCE etc.).

The taskbar includes transparency and color settings for the font, icons, border, and background. It also supports multihead setups, customized mouse actions, a built-in clock, a battery monitor and a system tray.

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

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

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.

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.

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.

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.

This package provides a wlroots-compatible Wayland color picker.

xscreensaver is a popular screen saver collection with many entertaining demos. It also acts as a nice screen locker.

xbanish hides the mouse cursor when you start typing, and shows it again when the mouse cursor moves or a mouse button is pressed.
