I just installed standard Ubuntu. I see Settings > Night Light. I see I can set 1 schedule. I'd like to set a more complex schedule with different Color Temperatures at different times of day. Effectively customizing the "Day Light" in addition to the "Night Light". That is, I want to run a weaker Night Light at day and a stronger Night Light at night.
gsettings get
command).org.gnome.settings-daemon.plugins.color night-light-temperature
or similar are used? I want to find the interface for Settings>Night Light and tweak it. So more generally: how do I browse the OS source code? It should be directly on my system, right?
