I have openSUSE 12.3 running on a Lenovo X220 tablet and bluetooth is always on and will not turn off. Using the bluetooth tray icon in KDE to turn it off does nothing, however if i make bluetooth discoverable and then turn it off it says it is off but the status light on my laptop says it is still on. How can i get bluetooth to stay off?
You should be able to disable it with
sudo /usr/sbin/rfkill block bluetooth
Re-enable it with
sudo /usr/sbin/rfkill unblock bluetooth
I guess if you would like to make sure it stays off, you could add it to a startup script if desired.
