how to disable bluetooth on startup?

[loewenblum]

hello community

When I start my lubuntu (ubuntu 18.04.1 lts) I always have to manually turn off the bluetooth connection.
Is there a way to turn it off completely, so that it doesn't start again?

I couldn't find a working solution in the internet.
Maybe you could help.

best regards,

sudo systemctl disable bluetooth --now

To go along with aromo2's suggestion: to deactivate bluetooth on startup run this

sudo systemctl disable bluetooth.service

then on next reboot bluetooth will not be active ... to view status issue

sudo systemctl status bluetooth.service

to activate bluetooth on startup run this

sudo systemctl enable bluetooth.service

thank you, it works!

Hi there,

For me it didn't work just to disable bluetooth with the following code:

sudo systemctl disable bluetooth.service

, because after a restart, bluetooth was enabled again.

I found and alternative solution, and that would be the following (I use nano, feel free to use any other text editor):

Step 1:
Navigate to the folder:

/etc/systemd/system/

Step 2:
First create a script that will kill the bluetooth service once run:

nano bluetoothkill.sh

Step 3:
Instert the following script:

#!/bin/bash
rfkill block bluetooth
exit 0

Step 4:
Create a foo.service file in the same folder

/etc/systemd/system/

:

nano foo.service

Step 5:
Insert the following script:

[Unit]Details=Additional startup scripts
After=network.target


[Service]
ExecStart=/etc/systemd/system/bluetoothkill.sh


[Install]
WantedBy=default.target

Step 6:
Run the following command in the terminal:

sudo systemctl start foo.service

Step 7:
Restart the machine and on the next boot you will notice that the Bluetooth service is no longer enabled by default on startup. You can still enable it when ever you like in the settings, or the terminal it is behaving without any errors.

If you like to add more scripts on startup, you can always edit the

foo.service

file and add additional lines under the [Service] bracket to run additional scripts on startup, for example:

ExecStart=/full-script-filepath/newscript.sh

Thanks, works great

Why not simply blacklisting the BT driver instead of deeply manipulating the system?!

This is like laslozr's suggestion, but with less steps.

Using sudo, open this file in your favourite text editor: /etc/rc.local

Below the commented out text (lines starting with #) and above the line that has "exit 0", add the following:

rfkill block bluetooth

If you haven't edited this file before, then it should look like this after your change:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
rfkill block bluetooth
exit 0

Save and then reboot.

To re-enable Bluetooth, you just flip the switch in Settings or in the Status Area dropdown. This way there's no need for sudo commands in the terminal to use Bluetooth when you need it. The above just turns off Bluetooth's state on start-up, but allows you to re-enable it. This has worked for me in 16.04 and 18.04.

Your solution worked with me, with a tweak. I have Ubuntu 18.04 LTS and there is no etc/rc.local file or folder. However, there is a Bluetooth folder in etc. Inside there is input.conf file. I wrote there the code at the end, like this:

# Configuration file for the input service

# This section contains options which are not specific to any
# particular interface
[General]


# Set idle timeout (in minutes) before the connection will
# be disconnect (defaults to 0 for no timeout)
#IdleTimeout=30


# Enable HID protocol handling in userspace input profile
# Defaults to false (HIDP handled in HIDP kernel module)
#UserspaceHID=true


rfkill block bluetooth
exit 0

And bluetooth is turned off at start-up and can be turned on from settings.

Good that you got it working. Mind you, I'm not sure you need the "exit 0" at the end, as that file isn't a script, it's just a conf file.

Also, I learnt that 18.04 LTS doesn't come with /etc/rc.local now, but I also learnt that if you add /etc/rc.local, make it executable, and add "#!/bin/sh -e" on the first line and "exit 0" on the last, then it'll work as I mentioned above. It came with 16.04, which I upgraded from to 18.04, hence why I've still got it and it works for me. I didn't know that rc.local isn't in use by default in 18.04, so good to learn something new. Cheers!
