I tried to use GNOME Nightlight in Ubuntu 17.04. The settings only allow me to turn it on and adjust the time. Is it possible to adjust the intensity or temperature of the hue? Currently, it's a bit too much.

gsettings set org.gnome.settings-daemon.plugins.color night-light-temperature <temperature>

Here are some temperatures values I determined myself (probably not correct):

  • 1000 Lowest value (really red)
  • 4000 Default night light temperature
  • 5500 More pleasant and less intense night light temperature
  • 6500 Default temperature (night light off)
  • 10000 Highest value (really blue)

    Also confirming this has worked on Ubuntu 18.04. I found 5000 to be the sweet spot for me. – The Gripmaster Jul 21 '19 at 14:46
  • It would be great if we could adjust the brightness – Pithikos Nov 7 '19 at 18:30
  • I'm also using Ubuntu 18.04 but for me the above command doesn't have any effect, also not after switching the nightlight off and on again. Any idea what's going wrong for me? – Alfe Mar 24 at 23:47

There's now a GNOME shell extension called "Night Light Slider" that works quite nicely:

In case you don't already have shell extensions running, here's a good overview of what to do: How do I install and manage GNOME Shell extensions?

    Great extension, the little slider is just what I wanted. Works out of the box on Ubuntu 18.04.3 – m.raynal Nov 26 '19 at 13:38

Install dconf editor for ubuntu. You can do that using the software installer that comes with ubuntu. Then search for "night" Choose the tab for night light temperature. Choose custome mode and set the value. I prefer already mentioned 5500. 4000 is too much for eye.
