Bluetooth is always turned on when on startup. How do I fix this problem?

  • 772

A few days ago I turned on Bluetooth on my laptop and then turned it off.

Now I see every time I start the laptop, I see the Bluetooth is turned on and I should turn it off manually and sometimes I forget.

How should I fix this problem? (I'm using Ubuntu 18.04)

startup bluetooth automount 18.04

  1. There are more technical solutions - none of which worked for me, at least, not without killing the manager or the adapter - so, after a couple of hours going around in circles, I gave in and made a simple "fix" - I wanted to keep the icon, essentially, but have bluetooth switched off at start up.

    1. Create a file, call it sbo.sh, the contents of which should be:
      #!/bin/bash
      sleep 1
      rfkill block bluetooth

    2. I saved this in /opt (any user space would do), then made sure I was owner:
      sudo chown myname:myname /opt/sbo.sh
      ...and that it was executable:
      sudo chmod u+x /opt/sbo.sh

    3. Then I opened "Startup Applications Preferences" Clicked on "Add" then entered the following details:
      Name: Switch Bluetooth Off
      Command: /opt/sbo.sh
      Comment: Switch off bluetooth but keep icon at start

    Seems to work. The one second pause ("sleep 1" in step 1) is important... it's enough of a lag for the device to become enabled. Doubtless not the most elegant work around, but after a couple of hours twiddling with things (like /etc/rc.local, systemd, etc.) to no avail... it's something that works.
