Question 120

On a production Linux workstation or server, a technician observes: An engineer applies Xorg-specific configuration while the user's actual graphical session is running under Wayland and no change takes effect. Which TWO complementary steps provide the best corrective action and its most direct diagnostic verification? Select TWO answers.

  1. Assume every Linux GUI is an Xorg server and that an Xorg configuration fragment necessarily controls a Wayland compositor.
  2. Identify the active graphical protocol and configure supported Xorg input overrides in the appropriate X configuration location or use the Wayland compositor's supported setting path.
  3. Distinguish the display manager that provides graphical login, the window manager that arranges application windows and the desktop environment supplying session tools; repair the failing layer.
  4. Check the session type, Xorg log or configuration fragments, effective keyboard layout and results after restarting an appropriate test session.
  5. Inspect DISPLAY and xauth entries, identify server hostname or SSH forwarding endpoint, and test authorized versus denied clients.

Explanation

Correct Answers

B:

Recommended administrative action: Identify the active graphical protocol and configure supported Xorg input overrides in the appropriate X configuration location or use the Wayland compositor's supported setting path. Linux principle: Xorg provides an X11 server with file-based configuration overrides; Wayland sessions use a different display architecture and may not honor Xorg driver configuration.

D:

Most direct verification evidence: Check the session type, Xorg log or configuration fragments, effective keyboard layout and results after restarting an appropriate test session. Linux principle: Xorg provides an X11 server with file-based configuration overrides; Wayland sessions use a different display architecture and may not honor Xorg driver configuration.

Incorrect Answers

A:

This shortcut is unsafe for the present Linux issue: Assume every Linux GUI is an Xorg server and that an Xorg configuration fragment necessarily controls a Wayland compositor. Xorg provides an X11 server with file-based configuration overrides; Wayland sessions use a different display architecture and may not honor Xorg driver configuration.

C:

This alternative addresses Display managers, window managers and desktop sessions, not the specific issue of Xorg configuration overrides and Wayland awareness: Distinguish the display manager that provides graphical login, the window manager that arranges application windows and the desktop environment supplying session tools; repair the failing layer. Linux principle: Xorg provides an X11 server with file-based configuration overrides; Wayland sessions use a different display architecture and may not honor Xorg driver configuration. Appropriate response: Identify the active graphical protocol and configure supported Xorg input overrides in the appropriate X configuration location or use the Wayland compositor's supported setting path. Root-cause evidence: Check the session type, Xorg log or configuration fragments, effective keyboard layout and results after restarting an appropriate test session. Independent acceptance: The configured keyboard behavior takes effect in the actual session type without overriding unrelated display or login components.

E:

This alternative addresses X11 display authorization and remote applications, not the specific issue of Xorg configuration overrides and Wayland awareness: Inspect DISPLAY and xauth entries, identify server hostname or SSH forwarding endpoint, and test authorized versus denied clients. Linux principle: Xorg provides an X11 server with file-based configuration overrides; Wayland sessions use a different display architecture and may not honor Xorg driver configuration.

Question 121

During an LPIC-1 practice lab, the operator encounters this condition: The GUI login screen fails to appear even though desktop applications start when a user manually runs a graphical session from the console. Which administrative step is the MOST appropriate way to resolve this issue? Select ONE best answer.

  1. Use a deliberate DISPLAY target and suitable X11 cookie-based authorization with xauth or properly restricted SSH X11 forwarding instead of unrestricted xhost access.
  2. Select an appropriate desktop family such as GNOME, KDE Plasma or Xfce, and choose a supported remote desktop protocol like VNC, RDP or SPICE according to session requirements.
  3. Treat the window manager as the same program as the graphical login manager and expect installing a desktop theme to repair a failed login service.
  4. Distinguish the display manager that provides graphical login, the window manager that arranges application windows and the desktop environment supplying session tools; repair the failing layer.

Explanation

Correct Answer

D:

Recommended administrative action: Distinguish the display manager that provides graphical login, the window manager that arranges application windows and the desktop environment supplying session tools; repair the failing layer. Linux graphical stacks separate X11 or Wayland display service, session selection, display manager login and window management responsibilities.

Incorrect Answers

A:

That option would use a deliberate DISPLAY target and suitable X11 cookie-based authorization with xauth or properly restricted SSH X11 forwarding instead of unrestricted xhost access, but it addresses a different concern. Linux graphical stacks separate X11 or Wayland display service, session selection, display manager login and window management responsibilities.

B:

Linux principle: Linux graphical stacks separate X11 or Wayland display service, session selection, display manager login and window management responsibilities. Appropriate response: Distinguish the display manager that provides graphical login, the window manager that arranges application windows and the desktop environment supplying session tools; repair the failing layer. Root-cause evidence: Inspect the enabled graphical login service, session files, login logs and active window manager, and attempt both local login and manual session startup. Independent acceptance: The login greeter starts reliably and the chosen session manages windows correctly without conflating the two roles.

C:

That option would treat the window manager as the same program as the graphical login manager and expect installing a desktop theme to repair a failed login service, but it addresses a different concern. Linux graphical stacks separate X11 or Wayland display service, session selection, display manager login and window management responsibilities.

Question 122

A helpdesk escalation describes this Linux behavior: The GUI login screen fails to appear even though desktop applications start when a user manually runs a graphical session from the console. Which Linux behavior or technical principle BEST explains why the issue occurs? Select ONE best answer.

  1. An X server accepts graphical client connections subject to transport reachability and authorization; DISPLAY alone does not grant permission and xhost + weakens access control.
  2. Desktop environments are replaceable collections of applications and session components; X11 forwarding and remote desktop protocols serve different access models.
  3. Treat the window manager as the same program as the graphical login manager and expect installing a desktop theme to repair a failed login service.
  4. Linux graphical stacks separate X11 or Wayland display service, session selection, display manager login and window management responsibilities.
