Will AutoEnable=false stop Bluetooth from automatically coming on during start-up in Ubuntu 24.04?

Are you tired of Bluetooth automatically turning on every time you start up your Ubuntu 24.04 machine? Do you want to take control of your Bluetooth settings and decide when you want to use it? You’re in the right place! In this article, we’ll dive into the world of Linux and explore if setting AutoEnable=false will indeed stop Bluetooth from automatically coming on during start-up in Ubuntu 24.04, specifically on a Lenovo ThinkPad AMD Ryzen7 laptop.

What is AutoEnable=false, and how does it work?

Before we dive into the solution, let’s take a step back and understand what AutoEnable=false is and how it works. AutoEnable is a parameter in the Bluetooth configuration file that determines whether Bluetooth should be enabled automatically during start-up. By default, AutoEnable is set to true, which means Bluetooth will turn on automatically when you boot up your system.

<code>/etc/bluetooth/main.conf</code>

In this file, you’ll find the following line:

<code>AutoEnable=true</code>

By setting AutoEnable=false, you’re essentially telling the system not to enable Bluetooth automatically during start-up. But will it really stop Bluetooth from coming on?

Setting AutoEnable=false in Ubuntu 24.04

To set AutoEnable=false, you’ll need to edit the main.conf file using a text editor with root privileges. Here’s how:

<code>sudo gedit /etc/bluetooth/main.conf</code>

Or, if you prefer the terminal:

<code>sudo nano /etc/bluetooth/main.conf</code>

Once you’ve opened the file, locate the line that starts with AutoEnable= and change the value to false:

<code>AutoEnable=false</code>

Save the changes and exit the text editor.

Will AutoEnable=false stop Bluetooth from automatically coming on during start-up?

Now that you’ve set AutoEnable=false, the question is, will it actually stop Bluetooth from coming on during start-up? The answer is… it depends.

Scenario	Result
Default Ubuntu 24.04 installation	Bluetooth will still turn on automatically during start-up.
Lenovo ThinkPad AMD Ryzen7 with Bluetooth enabled in BIOS	Bluetooth will still turn on automatically during start-up.
Custom installation with Bluetooth drivers manually installed	Bluetooth will not turn on automatically during start-up.

As you can see, the result varies depending on the specific scenario. If you’ve installed Ubuntu 24.04 with the default settings or have Bluetooth enabled in your BIOS, setting AutoEnable=false might not be enough to stop Bluetooth from coming on during start-up.

What else can I do to disable Bluetooth during start-up?

If setting AutoEnable=false doesn’t work for you, here are some additional steps you can take to disable Bluetooth during start-up:

1. Disable Bluetooth in your BIOS settings. This will vary depending on your laptop model, so refer to your user manual or online documentation for instructions.

2. Use a systemd service to disable Bluetooth during start-up. You can do this by creating a new file in the /etc/systemd/system directory:

   <code>sudo nano /etc/systemd/system/disable-bluetooth.service</code>
   

   And adding the following content:

   <code>
   [Unit]
   Description=Disable Bluetooth
   Before=bluetooth.service
   
   [Service]
   Type=oneshot
   Exec=/usr/bin RFKILL block bluetooth
   
   [Install]
   WantedBy=multi-user.target
   </code>
   

   Save the changes, then reload the systemd daemon and enable the service:

   <code>sudo systemctl daemon-reload</code>
   <code>sudo systemctl enable disable-bluetooth.service</code>
   

3. Use a script to disable Bluetooth during start-up. You can add a script to your /etc/rc.local file to disable Bluetooth:

   <code>sudo nano /etc/rc.local</code>
   

   And adding the following line before the exit 0 statement:

   <code>/usr/bin/rfkill block bluetooth</code>
   

   Save the changes and make the file executable:

   <code>sudo chmod +x /etc/rc.local</code>
   

Conclusion

Setting AutoEnable=false can be a useful step in disabling Bluetooth during start-up in Ubuntu 24.04, but it’s not a guarantee that it will work in every scenario. By combining this with other methods, such as disabling Bluetooth in your BIOS settings or using systemd services and scripts, you can take control of your Bluetooth settings and decide when you want to use it. Remember to test your changes thoroughly to ensure they work as intended.

• Q: Can I set AutoEnable=false for specific Bluetooth devices?

  A: No, the AutoEnable parameter is a global setting that applies to all Bluetooth devices. If you want to disable specific devices, you’ll need to use other methods, such as blacklisting the device or using udev rules.

• Q: Will setting AutoEnable=false affect my Ubuntu 24.04 system performance?

  A: No, setting AutoEnable=false has no significant impact on system performance. Bluetooth is a relatively lightweight service, and disabling it during start-up will not noticeably affect your system’s performance.
