Using Ubuntu 18.04 and GNOME Shell 3.28.1.
Every time I start my computer, I have to
- enable a certain non-system extension I'd like to use, and
- I have to disable Night Light.
Some system extensions have always been reactivated after a reboot, despite the fact I disabled them. I had to remove them from
Night Light is always set up with some really strange schedulde. If I correct it, it will be resetted after an undefined amount of time.
I'm guessing some configuration file is broken or has the wrong access rights. But I can't figure out which one.
