The Nvidia driver didn’t support some protocol that AMD/Intel did that was used by desktops for the night light.
Yes, they could have made the night light work. But why would they when Nvidia said the feature was coming soon? Well it turned out that soon was taking a very long time and eventually KDE actually did create a special night light implementation just for Nvidia. The problem was that it was a hack that had extra overhead. And in the end the hack didn’t get shipped because Nvidia finally starting supporting the protocol.
Not AI.
My bad on the Apple part.
