That symptom concerns A Linux graphical login policy needs the component responsible for accepting credentials and launching desktop sessions. This concerns a separate requirement, not the one being tested. The relevant failure is Changing xhost permissions does not change behavior of a native Wayland application. The current requirement calls for a different check.

That symptom concerns An X11 administrator must authorize an individual client using a cookie rather than globally disabling access control. This concerns a separate requirement, not the one being tested. The relevant failure is Changing xhost permissions does not change behavior of a native Wayland application. The current requirement calls for a different check.

That symptom concerns A remote X11 client must display on the intended workstation X server rather than the local default. This concerns a separate requirement, not the one being tested. The relevant failure is Changing xhost permissions does not change behavior of a native Wayland application. The current requirement calls for a different check.

This fix is aimed at Changing window-decoration settings has no effect on the graphical login prompt. and would be relevant if A Linux graphical login policy needs the component responsible for accepting credentials and launching desktop sessions. The incident instead states Changing xhost permissions does not change behavior of a native Wayland application. and needs Identify the display protocol first and use compositor-appropriate configuration.

This fix is aimed at The application connects to the wrong X server because DISPLAY points to an unrelated session. and would be relevant if A remote X11 client must display on the intended workstation X server rather than the local default. The incident instead states Changing xhost permissions does not change behavior of a native Wayland application. and needs Identify the display protocol first and use compositor-appropriate configuration.

This fix is aimed at The admin edited a fragment in an ignored directory, so the layout does not change. and would be relevant if An Xorg keyboard layout override should apply through a maintainable configuration fragment. The incident instead states Changing xhost permissions does not change behavior of a native Wayland application. and needs Identify the display protocol first and use compositor-appropriate configuration.

Place a small keyboard InputClass configuration under /etc/X11/xorg.conf.d/ where supported. That operation is designed for the different case: An Xorg keyboard layout override should apply through a maintainable configuration fragment. It does not perform the specific action required here: Configure the active display manager, such as GDM, rather than a window manager alone.

Set DISPLAY to the target X server address/display using the environment approved by administrators. That operation is designed for the different case: A remote X11 client must display on the intended workstation X server rather than the local default. It does not perform the specific action required here: Configure the active display manager, such as GDM, rather than a window manager alone.

Check the session type, for example echo "$XDG_SESSION_TYPE", and use tools appropriate to that server. That operation is designed for the different case: An administrator must identify whether the desktop session uses X11 or Wayland before applying X11-specific controls. It does not perform the specific action required here: Configure the active display manager, such as GDM, rather than a window manager alone.

This explains another Linux operation, namely Set DISPLAY to the target X server address/display using the environment approved by administrators., where The X11 DISPLAY variable selects the X server where the client's graphics are rendered. It does not explain why Configure the active display manager, such as GDM, rather than a window manager alone. satisfies the stated condition.

This explains another Linux operation, namely Check the session type, for example echo "$XDG_SESSION_TYPE", and use tools appropriate to that server., where Wayland and X11 have different security and display architectures; X11-only settings may not control a native Wayland compositor. It does not explain why Configure the active display manager, such as GDM, rather than a window manager alone. satisfies the stated condition.

This explains another Linux operation, namely Provision the appropriate MIT-MAGIC-COOKIE authentication data using xauth., where xauth manages X authorization records, while an unrestricted xhost setting can broaden server access. It does not explain why Configure the active display manager, such as GDM, rather than a window manager alone. satisfies the stated condition.

That observation checks A remote X11 client must display on the intended workstation X server rather than the local default. In this scenario it does not demonstrate Configure the active display manager, such as GDM, rather than a window manager alone.; the relevant evidence must establish The configured graphical login screen appears and launches the chosen desktop after authentication.

That observation checks An Xorg keyboard layout override should apply through a maintainable configuration fragment. In this scenario it does not demonstrate Configure the active display manager, such as GDM, rather than a window manager alone.; the relevant evidence must establish The configured graphical login screen appears and launches the chosen desktop after authentication.

That observation checks An administrator must identify whether the desktop session uses X11 or Wayland before applying X11-specific controls.

This fix is aimed at Changing xhost permissions does not change behavior of a native Wayland application. and would be relevant if An administrator must identify whether the desktop session uses X11 or Wayland before applying X11-specific controls. The incident instead states Changing window-decoration settings has no effect on the graphical login prompt. and needs Modify the active display manager's login configuration instead of window-manager appearance settings.

This fix is aimed at The admin edited a fragment in an ignored directory, so the layout does not change. and would be relevant if An Xorg keyboard layout override should apply through a maintainable configuration fragment. The incident instead states Changing window-decoration settings has no effect on the graphical login prompt. and needs Modify the active display manager's login configuration instead of window-manager appearance settings.

This fix is aimed at The admin ran xhost + and any unauthenticated network client can connect. and would be relevant if An X11 administrator must authorize an individual client using a cookie rather than globally disabling access control. The incident instead states Changing window-decoration settings has no effect on the graphical login prompt. and needs Modify the active display manager's login configuration instead of window-manager appearance settings.

Configure a VNC-capable remote desktop service with controlled authentication and transport security. That operation is designed for the different case: An admin must give remote operators visibility into a graphical session without logging directly into the physical console. It does not perform the specific action required here: Evaluate Xfce as the desktop environment rather than installing only a window manager.

Identify GNOME and KDE Plasma as full desktop environments, rather than remote display protocols. That operation is designed for the different case: An administrator needs to recognize the difference between GNOME and KDE Plasma on managed Linux desktops. It does not perform the specific action required here: Evaluate Xfce as the desktop environment rather than installing only a window manager.

Check the session type, for example echo "$XDG_SESSION_TYPE", and use tools appropriate to that server. That operation is designed for the different case: An administrator must identify whether the desktop session uses X11 or Wayland before applying X11-specific controls. It does not perform the specific action required here: Evaluate Xfce as the desktop environment rather than installing only a window manager.

This explains another Linux operation, namely Configure a VNC-capable remote desktop service with controlled authentication and transport security., where VNC transmits desktop framebuffer updates and inputs, unlike SSH text shells; exposed VNC should be protected appropriately. It does not explain why Evaluate Xfce as the desktop environment rather than installing only a window manager. satisfies the stated condition.

This explains another Linux operation, namely Identify GNOME and KDE Plasma as full desktop environments, rather than remote display protocols., where These suites provide session integration and desktop applications; protocols such as RDP describe remote access instead. It does not explain why Evaluate Xfce as the desktop environment rather than installing only a window manager. satisfies the stated condition.

This explains another Linux operation, namely Set DISPLAY to the target X server address/display using the environment approved by administrators., where The X11 DISPLAY variable selects the X server where the client's graphics are rendered. It does not explain why Evaluate Xfce as the desktop environment rather than installing only a window manager. satisfies the stated condition.

That observation checks An administrator needs to recognize the difference between GNOME and KDE Plasma on managed Linux desktops. In this scenario it does not demonstrate Evaluate Xfce as the desktop environment rather than installing only a window manager.; the relevant evidence must establish The session launches with its panel, settings tools and file manager at the desired resource footprint.

That observation checks An admin must give remote operators visibility into a graphical session without logging directly into the physical console. In this scenario it does not demonstrate Evaluate Xfce as the desktop environment rather than installing only a window manager.; the relevant evidence must establish The session launches with its panel, settings tools and file manager at the desired resource footprint.

That observation checks A visually impaired user needs the graphical interface read aloud while navigating dialogs. In this scenario it does not demonstrate Evaluate Xfce as the desktop environment rather than installing only a window manager.; the relevant evidence must establish The session launches with its panel, settings tools and file manager at the desired resource footprint.

This fix is aimed at The inventory labels RDP as the installed graphical desktop environment. and would be relevant if An administrator needs to recognize the difference between GNOME and KDE Plasma on managed Linux desktops. The incident instead states A standalone window manager opens windows but provides no desired integrated desktop workflow. and needs Install and select the intended Xfce desktop session, not just a window manager.

This fix is aimed at An SSH-only shell is reachable but no graphical desktop is available to remote operators. and would be relevant if An admin must give remote operators visibility into a graphical session without logging directly into the physical console. The incident instead states A standalone window manager opens windows but provides no desired integrated desktop workflow. and needs Install and select the intended Xfce desktop session, not just a window manager.
