Description Guilherme Salazar 2024-04-21 14:12:43 UTC

SUMMARY

Night colors does not revert back to day color settings.
It only does so if one opens the settings page and interacts with it - for example, by clicking the color temperature slider. It does not even need to be applied; once the preview ends, the correct color is applied.


STEPS TO REPRODUCE
1. Set color temperature and day/night times


OBSERVED RESULT

Day settings are not applied when day time starts

EXPECTED RESULT

Day time settings are applied automatically when day time starts

ADDITIONAL INFORMATION

I thought this was the same as https://bugs.kde.org/show_bug.cgi?id=461657; however, I verified the proposed fix _is_ in my current kwin version.

This also looks similar to https://bugs.kde.org/show_bug.cgi?id=413406, but in my case night colors are correctly applied.

Comment 1 Guilherme Salazar 2024-04-22 10:47:05 UTC

Just opened up my laptop for the day - before I fix the color temp, I ran the following command to get some more data:

```
$ qdbus org.kde.KWin /ColorCorrect GetAll org.kde.kwin.ColorCorrect
available: true
currentTemperature: 6500
enabled: true
inhibited: false
mode: 2
previousTransitionDateTime: 1713776400
previousTransitionDuration: 1800000
running: true
scheduledTransitionDateTime: 1713819600
scheduledTransitionDuration: 1800000
targetTemperature: 6500
```

You can see it reports the correct temperature for the day time (6500), even though it's still in 2100 (which is my setting for night time).

Comment 2 Guilherme Salazar 2024-04-24 10:26:50 UTC

I believe this is only happening when I close the laptop's lid after night mode is on; then, when I open, it fails to set day temp. I will verify tonight.

Comment 4 Nate Graham 2025-08-01 22:35:37 UTC

This has been working for me for quite some time now. Is anyone still able to reproduce it in Plasma 6.4 or later?
