## Describe the bug

killall gsd-color is currently the only way for me to get the night light mode up and running. Unfortunately, that's not permanent either.

There are some open issues with problems with the night light mode. Also in the indicator repository.

Do you see a solution?

### To Reproduce
Steps to reproduce the behavior:
If that were that easy to figure out, I'd definitely do it! ;)

### Expected behavior
My simple expectation as a user is that I don't have to bother with the terminal to be able to visibly start the nightlight mode that is already activated and defined in the switchboard settings.
