Turn Off Bluetooth By Default in Ubuntu [Quick Tip]

I recently bought a new Dell Inspiron 7437 and one of the first few things I did was to dual boot the pre-installed Windows with Ubuntu. My older laptop did not have Bluetooth, strange but true. This is why I never noticed that bluetooth is always on at each boot in Ubuntu.

Since, I hardly use Bluetooth, so why should I have Bluetooth enabled by default? It impacts the battery life a little after all.

While you can turn off Bluetooth in one click in Ubuntu, doing it in each session is a repetitive and frustrating task.

A simpler solution is to deactivate Bluetooth at start up in Ubuntu.

In this quick post, I’ll share with you how to disable Bluetooth by default at each start up.

The new method is using systemd to disable any service including Bluetooth. All you have to do is to run this command in the terminal:

sudo systemctl disable bluetooth.service

I hope you find this quick little tip helpful.

  • Why is “turn off bluetooth by default” considered the “old” way of doing things?

    It’s certainly the most secure way to handle that functionality. If you’re in a public space, allowing your computer to communicate to any bluetooth device by default is a security fail.

  • i tried the systemd command suggested on ubuntu 20.04 and found that the icon disappeared from notification area, requiring to manually start the service every time bluetooth is needed
    for me a better solution was to edit the file /etc/bluetooth/main.conf changing the line AutoEnable=true to AutoEnable=false, so the service is started but the adapter is off and can be turned on when needed from the notification icon
