Thanks. This means the kernel can't detect anything plugged into HDMI:

/sys/class/drm/card0-HDMI-A-1/enabled:disabled

So if not a kernel bug then most likely the cable isn't plugged in properly, or the cable needs replacing. Please try a different HDMI cable.

Hello!
Many thanks for your help. The cable I have changed and connected
another monitor. Always the same result.
Best regards

In that case this is either a problem with the HDMI socket on the computer or a kernel bug.
