That observation checks A Linux graphical login policy needs the component responsible for accepting credentials and launching desktop sessions. In this scenario it does not demonstrate Provision the appropriate MIT-MAGIC-COOKIE authentication data using xauth.; the relevant evidence must establish The approved client's connection works with its cookie and an untrusted client remains denied.

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 Provision the appropriate MIT-MAGIC-COOKIE authentication data using xauth.; the relevant evidence must establish The approved client's connection works with its cookie and an untrusted client remains denied.

That observation checks An administrator must identify whether the desktop session uses X11 or Wayland before applying X11-specific controls. In this scenario it does not demonstrate Provision the appropriate MIT-MAGIC-COOKIE authentication data using xauth.; the relevant evidence must establish The approved client's connection works with its cookie and an untrusted client remains denied.

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 The admin ran xhost + and any unauthenticated network client can connect. and needs Replace broad host-based access with the intended xauth cookie distribution.

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 The admin ran xhost + and any unauthenticated network client can connect. and needs Replace broad host-based access with the intended xauth cookie distribution.

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 The admin ran xhost + and any unauthenticated network client can connect. and needs Replace broad host-based access with the intended xauth cookie distribution.

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: Place a small keyboard InputClass configuration under /etc/X11/xorg.conf.d/ where supported.

Configure the active display manager, such as GDM, rather than a window manager alone. That operation is designed for the different case: A Linux graphical login policy needs the component responsible for accepting credentials and launching desktop sessions. It does not perform the specific action required here: Place a small keyboard InputClass configuration under /etc/X11/xorg.conf.d/ where supported.

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: Place a small keyboard InputClass configuration under /etc/X11/xorg.conf.d/ where supported.

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 Place a small keyboard InputClass configuration under /etc/X11/xorg.conf.d/ where supported. satisfies the stated condition.

This explains another Linux operation, namely Configure the active display manager, such as GDM, rather than a window manager alone., where A display manager controls the graphical login and session start, while a window manager mainly arranges application windows. It does not explain why Place a small keyboard InputClass configuration under /etc/X11/xorg.conf.d/ where supported. 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 Place a small keyboard InputClass configuration under /etc/X11/xorg.conf.d/ where supported. satisfies the stated condition.

That observation checks An administrator must identify whether the desktop session uses X11 or Wayland before applying X11-specific controls. In this scenario it does not demonstrate Place a small keyboard InputClass configuration under /etc/X11/xorg.conf.d/ where supported.; the relevant evidence must establish Restarting Xorg uses the desired layout while unrelated graphics settings remain intact.

That observation checks A Linux graphical login policy needs the component responsible for accepting credentials and launching desktop sessions. In this scenario it does not demonstrate Place a small keyboard InputClass configuration under /etc/X11/xorg.conf.d/ where supported.; the relevant evidence must establish Restarting Xorg uses the desired layout while unrelated graphics settings remain intact.

That observation checks An X11 administrator must authorize an individual client using a cookie rather than globally disabling access control. In this scenario it does not demonstrate Place a small keyboard InputClass configuration under /etc/X11/xorg.conf.d/ where supported.; the relevant evidence must establish Restarting Xorg uses the desired layout while unrelated graphics settings remain intact.

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 The admin edited a fragment in an ignored directory, so the layout does not change. The current requirement calls for a different check.

The incident instead states The admin edited a fragment in an ignored directory, so the layout does not change. and needs Place the correct InputClass fragment in the active Xorg configuration directory.

Provision the appropriate MIT-MAGIC-COOKIE authentication data using xauth. That operation is designed for the different case: An X11 administrator must authorize an individual client using a cookie rather than globally disabling access control.

It does not perform the specific action required here: Check the session type, for example echo "$XDG_SESSION_TYPE", and use tools appropriate to that server.

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 Check the session type, for example echo "$XDG_SESSION_TYPE", and use tools appropriate to that server. satisfies the stated condition.

That observation checks An Xorg keyboard layout override should apply through a maintainable configuration fragment. In this scenario it does not demonstrate Check the session type, for example echo "$XDG_SESSION_TYPE", and use tools appropriate to that server.; the relevant evidence must establish The diagnostic reports the expected session type and the selected tool affects that session.
