Hi,

The night light feature isn’t working in Fedora 39.

Below is the output when I try to switch color profiles for my two monitors. When turning night light on/off, there’s no output.

$ gnome-control-center --verbose

An easy fix:

With gnome-control-center, I used “Color” to select a Profile for each monitor, e.g., “Standard Space - sRGB” and then used “Displays” to switch “Night Light” Off to On .

/usr/libexec/gdm-wayland-session /usr/bin/gnome-session
Linux localhost 6.6.13-200.fc39.x86_64
