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.


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.
