3. I expect when the Night Light settings are set, then it should be
working as specified.
4. Instead the Night Light settings only work for a few seconds, and
then it went back to the original display state as if Night Light is not
enabled.
This only happens when I'm booting with kernel 5.4.0-66-generic, and
everything works like a charm when booting with kernel 5.4.0-65-generic.
Please help looking into this.
