Relative novice, sorry if I get some details/terms wrong. Been running a KDE Plasma install for about 9 months and it’s awesome. Since I did a last update from the desktop, the nighttime color temp settings don’t change. It’s always warm unless I manually suspend it. I tried undoing and redoing the setting. The clock is correct and settings all seem correct, but it won’t cycle. Any help you have is appreciated in advance.
What distro and Plasma version are you using? Additionally, do you have it set for a specific time or based on location? If it’s the latter, then you need to check if geoclue2 installed.
Hey! Thanks for stepping in. This is what Uname -A gets me:
Linux winux 6.14.0-33-generic #33~24.04.1-Ubuntu SMP PREEMPT_DYNAMIC Fri Sep 19 17:02:30 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
And my Info Center says this:
Operating System: KDE neon User Edition KDE Plasma Version: 6.5.0 KDE Frameworks Version: 6.19.0 Qt Version: 6.9.2 Kernel Version: 6.14.0-33-generic (64-bit) Graphics Platform: Wayland Processors: 8 × 13th Gen Intel® Core™ i3-1315U Memory: 8 GiB of RAM (7.5 GiB usable) Graphics Processor: Intel® Graphics Manufacturer: LENOVO Product Name: 82X7 System Version: IdeaPad Slim 3 15IRU8
And this is my configuration page for the night light setting, which appears to be set for specific times:


I did some research and couldn’t find anything recent that fits your issue. However, using your time settings gave me a tinted screen even though it should still be considered day time. Changing the sunset time to 11:59 PM made it work correctly, but setting it to 12:00 AM or later made it change early. I think this is probably a bug.
Woah! This is the second best tech support I’ve had this year. Thank you for 1. Identifying a bug, and 2. Offering a workaround same day!
You have my gratitude.
