GNOME Bugzilla – Bug 778668
Night Light: Gradually transition on or off
Last modified: 2017-02-16 05:22:50 UTC
gnome-settings-daemon 3.23.90-0ubuntu1 Ubuntu GNOME 17.04 Alpha, running GNOME Shell 3.22.4-1ubuntu1 Please take several seconds to gradually change the color temperature when transitioning on or off. This is how f.lux works and it's how Night Light in the Windows 10 Creators Update (in Insider testing) works.
