Night light not working

[librem5]

Is night light working on Librem 5 (PureOS) ?
I don’t see it taking it effect so wanted to check.

Yes it does:

@patch

Without wishing to blind anyone by making them stare at their own Librem 5 LEDs.

Settings -> Display -> Night Light.
It’s basically screen filter. It makes display yellow-ish

[Quarnero]

Settings/Displays/Night Light: I do not notice any change. And, I recall now:

@reC

don’t use that if you can afford not to …

@reC

that is only a color filter meant as a last resort for people who don’t know or don’t care about a proper hardware calibration in regards to the ambient light.

That feature it not yet available to L5, it need work on kernel. I waiting this feature too to mitigate invisible blue light.

In this post, @dos said:

BTW. That’s actually lack of support for adjusting gamma ramps in kernel’s display stack.

What does this mean? Does this prevent the gammastep package from working too?

Is it still a work in progress? Thanks in advance

It is not yet implemented, but i am 102% confident that @dos & @cat will perform this feature soon to L5.
As far i know the regular pinephone is the only device that already has enabled this feature.

They are probably busy with something more important I’ll wait
Thanks

I just noticed yesterday that pinephone-pro already support linux-gamma-ramps, it is a shame that the librem 5 still not.
