The error occurs due to a timeout while configuring the HDMI output. In some display configurations, it waits for user input or an interrupt while the DRM/KMS operation is active.
Execute the output command and provide an interrupt (press the Enter key) after approximately 10–14 seconds. Then check whether the output is configured successfully.
If the output is set correctly, the console log will appear as shown below.
