Public bug reported:
The Display settings have a "Night Light" option which allows reducing blue
light at night.
In Ubuntu 17.10, this worked great, and the setting took effect on all 3 of my
monitors.
In Bionic, only the 1st monitor is affected; the other 2 remain at the default
color temperature.
