x11-utils binary package in Ubuntu Noble amd64

 An X client is a program that interfaces with an X server (almost always via
 the X libraries), and thus with some input and output hardware like a
 graphics card, monitor, keyboard, and pointing device (such as a mouse).

 that ship with the X Window System, including:

  - xdpyinfo, a display information utility for X;
  - xdriinfo, query configuration information of DRI drivers;
  - xev, an X event displayer;
  - xfd, a tool that displays all the glyphs in a given X font;
  - xfontsel, a tool for browsing and selecting X fonts;
  - xkill, a tool for terminating misbehaving X clients;
  - xlsatoms, which lists interned atoms defined on an X server;
  - xlsclients, which lists client applications running on an X display;
  - xlsfonts, a server font list displayer;
  - xmessage, a tool to display message or dialog boxes;
  - xprop, a property displayer for X;
