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 /usr/share/gnome-shell/extensions.

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.

  • regarding the "Night Light", Can you check with dconf tool? or command line gsettings set org.gnome.settings-daemon.plugins.color night-light-enabled false i.stack.imgur.com/k3jCC.png

  • The thing is that Night light might be on depending on the current time. For example right now, the schedule is set from 5:00 to 17:00 (it is 11:40 here). Disabling it keeps it off until I restart.

  • have you tried above command? ok just to manipulate can you adjust your night light to "manual" and set only 1minute. i.stack.imgur.com/lJjRW.png

  • Yes I did, but what should I see? It was already off. I did what you want, what should I look after now?

  • I set it to 12:00-12:01, now at 12:03 it resetted to 6:00-18:00

I got it working by removing some settings folders and just configuring everything from scratch. I found some valuable information in this answer: https://askubuntu.com/a/558450/548635

What I finally did is:

mv ~/.config/dconf ~/.config/dconf.old
mv ~/.gnome ~/.gnome.old
mv ~/.gconf ~/.gconf.old
