How to have KDE night color on start up

Hi there,

I should start by saying I am not so experienced at linux. So, I decided to give KDE a first try, it takes some getting used to coming from Gnome. I notice that this feature “Night Color” is similar to “Nightlight”, but I can’t manage to make it work at system start, I have to activate manually. It is set to “constant” but still won’t work at start.

it did not came out of the box with first install, I installed after I looked for it and did not find it, I do not know if that is normal or not.

I used [Fedora-KDE-Live-x86_64-31.torrent] 2019-10-28
cheksums were fine.

Operating System: Fedora 31
KDE Plasma Version: 5.17.4
KDE Frameworks Version: 5.64.0
Qt Version: 5.12.5
Kernel Version: 5.3.16-300.fc31.x86_64
OS Type: 64-bit
Processors: 8 × Intel® Core™ i5-8250U CPU @ 1.60GHz
Memory: 7.7 GiB of RAM

ok, thx.

Are your pressed the button “Apply”? Just no other guesses so far…

ha!, yeah, I did apply, I am using Redshift for the time being. I 'll figure it out , it is probably one of those obvious things.

(edit, Redshift actually works as intended, but not nightcolor).
