A1: evtest is a command-line utility in Linux used to capture detailed information about input devices, including keyboards. It allows users to monitor raw input devices beyond the graphical environments like X11 or Wayland. Q2: Why use evtest instead of other input capturers? A2: Unlike other tools that depend on graphical interface configurations, evtest operates directly with device files in the /dev/input directory. This allows it to capture inputs even in environments without a graphical user interface (GUI). A3: evtest can be installed from the package repositories of most Linux distributions.
