I am using Ubuntu 17.04 (budgie desktop), and I disabled the bluetooth service to prevent the bluetooth from being enabled with the computer startup. I used this command to disable it :
sudo systemctl disable bluetooth.service
And I used this command to confirm that it is disabled :
systemctl is-enabled bluetooth.service > disabled
But sometimes, the bluetooth (and some other services) are starting with the computer even if they are disabled. Is it a bug ? or am I missing something here ?
