GNOME Night Light Broken on Fedora 41 (Disappears After a Few Seconds)

Hi Fedora Friends,

I’m having trouble with Night Light on Gnome in Fedora 41. It keeps disappearing after a few seconds no matter what I do. I’ve seen similar reports across other distros (Arch, Ubuntu), so it seems like a somewhat widespread issue.

Here’s what I’ve tried so far with no success:

  • Switching to a manual schedule instead of sunset to sunrise
  • Creating a custom colour profile (same result with every profile I add)
  • Booting into different versions of the kernel
  • Setting up a different power profile (the result is the same regardless of the profile)

I’ve attached a screenshot of the information on my system from Gnome’s “About” settings.

Has anyone else experienced this and found a solution?

I noticed this issue isn’t listed under “common issues” on the Fedora Discussion forum. Since it seems to be affecting multiple users, might it be worth adding it there?

Any help would be greatly appreciated!

Cheers,
Igor

UPDATE: Never mind, I figured it out! Turns out it was a weird interaction with the power settings.

For anyone else experiencing this, here’s what I did to fix it:

  • Set up a manual schedule from 16:00 to 9:00 (it’s winter now in the UK)
  • Added a manual colour profile: sRGB
  • Switched off all power savers in the power menu (power mode: performance, switched off dim screen, screen blank, power saver, automatic suspend, power button behaviour: nothing)

Here’s my gnome-control-center debug output, in case it helps anyone diagnose the issue further:

I’m still seeing those “Clipping is broken” warnings, which might be related to GTK or my graphics drivers. But at least Night Light is working correctly now! Hopefully, this helps someone else.

Cheers,
Igor
