When you start XWindows, which series of programs and/or scripts would most closely describe the start-up process?

This sequence begins with xdm, which is the X Display Manager used for graphical login screens, not the standard startx path a user invokes from a console.

This sequence incorrectly places a desktop environment (kde) at the start and misorders xinit before xinitrc, which reverses the actual call chain.

This sequence places kde after Xclients, implying kde is a post-client process, and omits xinit entirely, skipping a required stage in the startup chain.

startx is the high-level shell wrapper a user runs to initiate an X session. It invokes xinit, the lower-level X initializer that starts the X server and client processes. xinit then executes the xinitrc configuration script, which defines the client environment and launches Xclients such as window managers and desktop applications. This layered chain - startx -> xinit -> xinitrc -> Xclients - accurately reflects the standard X startup architecture on Linux.

This sequence incorrectly places Xclients before xinitrc, reversing their relationship - xinitrc is the script that starts Xclients, so Xclients cannot appear before it.
