Comment 0 for bug 2066902

Since installing Ubuntu 24.04, every now and then Night Light gets stuck when my screen is locked at night and I unlock it in the morning. The screen is then very orange (more so than normally is the case with Night Light), and disabling it with the button in in the top bar menu does nothing.

The only ways to restore the screen to normal are disabling and enabling the colour profile or running `gdbus call -e -o /org/gnome/SettingsDaemon/Color -d org.gnome.SettingsDaemon.Color -m org.gnome.SettingsDaemon.Color.NightLightPreview 1`

I have never been able to find anything remotely relevant in any system logs regarding this issue. It also does not happen every day, but probably once every seven to ten days or so.

My PC has an AMD RX550 GPU using the amdgpu driver. I'm not sure if it makes a difference, but so far I've not seen this problem on my other machines with Intel IGPs.
