Turn off bluetooth at boot

Postby Idefix87 on Sat Feb 09, 2013 7:44 am

Hi all,

I do not see an option to turn off the bluetooth at boot. After searching I found a solution, but I that is a workaround and I'm not sure if it is the right solution.
The solution I found was to make a cron that kills the bluetooth at every boot. But there has to be a command first that starts the bluetooth right? What is that command and can I change that one?
I also tried the BUM manager, but that did not work out for me.

Thanks in advance!

Don't have a BT adaptor so I'm not sure. I assume you've tried preferences>startup applications? I'd guess that is a BT adaptor was found the system would start the daemon automatically. Perhaps you can deselect it here?

Hi,
Indeed I looked at preferences>startup applications, but the bluetooth was not there. I think it is some kind of hidden process that is started automatically. For now I solved this problem by adding the command 'rfkill block bluetooth' in that window. Only Iḿ not sure if this is the proper way to do it.

I am running KDE. I don't use bluetooth. I went to system settings, startup and shutdown, service manager and unchecked the box labled BlueDevil. That's what KDE calls it. I used to run Mint 13 Cinnamon and I think I found something there also.

Sorry for the late reply. I do'nt have a service manager or at least I couldn't find it ;)
The only thing I found was the start up applications and there the BT was not mentioned. Therefore I added the commando to kill the app at boot, because I can't find where it is started.
Maybe in a next edition it will be easier to find it :roll:

If your want to disable BT at boot-time, you only have to blacklist the bluetooth module (=driver) in order to prevent the kernel from loading it on reboot.
Code: Select all
sudo echo "blacklist bluetooth" > /etc/modprobe.d/blacklist-BT.conf

Then you can purge most of the Bluetooth-oriented packages (a few libs cannot be removed since it would completely uninstall some essential parts of your DE and/or destroy it).

Edit: on a working bluetooth-enabled system you should have something like these results
Code: Select all
$ lsmod|grep blu
bluetooth             147960  24 bnep,btusb,rfcomm
rfkill                 13361  2 bluetooth
crc16                   1288  2 ext4,bluetooth

and if BT is disabled, "lsmod|grep blu" will return no result.
