Question
When you start XWindows, which series of programs and/or scripts would most closely describe the start-up process?
Options
- Axdm -> xinit -> xinitrC.> Xclients
- BkdE.> xinitrC.> xinit -> Xclients
- Cstartx -> xinitrC.> Xclients -> kde
- Dstartx -> xinit -> xinitrC.> Xclients
- Estartx -> xinit -> Xclients -> xinitrc
Explanation
The X Window System startup sequence proceeds from the user-facing startx script through xinit, then xinitrc, which finally launches Xclients.
Common mistakes.
- A. 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.
- B. This sequence incorrectly places a desktop environment (kde) at the start and misorders xinit before xinitrc, which reverses the actual call chain.
- C. 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.
- E. This sequence incorrectly places Xclients before xinitrc, reversing their relationship - xinitrc is the script that starts Xclients, so Xclients cannot appear before it.
