Hi Guix,
After the recent core-updates merge which included GNOME 3.30, it appears
the the night light feature, which makes the screen colors warmer, doesn't
seem to work. It appears to activate fine via the setting and via the
timer, but the screen colors don't change. It also appears that colord
isn't running, which I suspect is related.

Commit 33f9778bc83086837b99e5c5e99cd514cb0d154e fixes this and colord
now starts correctly again.
I believe that should also fix the “night light” feature in GNOME. I
tested it in a VM but it was hard to tell if it was working.
Could you confirm, Jack?
Thanks,
Ludo’.

I can confirm it's working for me on GNOME on my thinkpad! I can use the
night light settings and the laptop screen was detected in the "Color"
section of the settings. And I can see the colord daemon is running.
This is awesome, thank you!
Marking 37911 as done, I'll let Jack close 37843 if he's happy with it.
Pierre
