I have disabled the bluetooth service using "systemctl disable bluetooth.service", and also using systemd-manager, but it still starts at boot-time. I'm using Ubuntu 18.04 amd64.
I suppose it is being activated by another service, but how can I find and stop it?
I would like to stop it from loading in the first place, rather than stop it afterwards by for example putting a line in /etc/rc.local. I also want to activate it when needed, and so not make bluetooth.service unexectuable or use similar hacks.
Thanks very much.
