Xinput GUI, or xinput-gui, is a simple GUI for Xorg's Xinput tool.
xinput is a command-line utility for managing, testing, and configuring X11 display server input devices. This includes mice, keyboards, and touchpads.
xinput-gui is a wrapper around the xinput command. It aims to simplify the configuration of X input devices for users who aren't as familiar with the terminal, while being more flexible than other tools provided by various desktop environments.
For installation instructions, see the project README.
