The GNOME Night Light feature is one of my favourite things in GNOME 3.24, but I’m not a fan of its default color temperature settings.
If you’d rather the feature was a little cooler or a little warmer too then keep reading, as we’ll show you how adjust color temperature settings for GNOME Night Light on Ubuntu 17.04
Tweak GNOME Night Light
GNOME Night Light is easy to enable and simple to schedule using your local timezone as a guide.
But you cannot tweak the temperature value through the System Menu option, or the System Settings > Display > Night Light panel.
You might have noticed in our post about new Budgie desktop features that their Night Light applet lets you adjust the color temperature from the applet.
A few readers commented that they’d opt to use GNOME Night Light feature in place of third-party apps like Red Shift as it lets them adjust color temperature, increase the warmness or coolness, and lower the intensity of the effect.
The good news is that it is possible to adjust color temperature for GNOME Night Light on Ubuntu (and other Linux desktops).
You just need to dive in to the desktop’s advanced settings to do it:
- Open
dconf-editor(install it if you don’t have it) - Navigate to
org/gnome/settings-daemon/plugins/color/night-light-temperature. - Enter a
customvalue
Here are some temperatures values to use as a guide:
- 1000 — Lowest value (super warm/red)
- 4000 — Default night light on temperature
- 5500 — Balanced night light temperature
- 6500 — Default night light off temperature
- 10000 — Highest value (super cool/blue)
You can readily undo any changes you make at any time by sliding the ‘use default value‘ switch to on.
