Public bug reported: Night light turns on and off correctly (manually and automatically at sunset/sunrise), but it has no effect on screen colour temperature. Altering the colour temperature slider makes no difference. Changing display temperature in dconf-editor didn't have any effect either. Behaviour is the same in Wayland and Xorg sessions.
(Note that 22.10 is the first ubuntu release where graphics have worked at all with this machine (Intel® Core™ i3-10100 CPU Intel CometLake-S GT2 [UHD Graphics 630]) With kernels before 5.19 the i915 driver module wouldn't load.) I have raised the issue on ubuntu forums, https://ubuntuforums.org/showthread.php?t=2481261 with no indication of it being a problem also reported by other 22.10 users, so it may be specific to this CPU. It also appears to be specific to gnome desktop. I have tried a Kubuntu liveUSB and night light worked correctly.
