I tried adding rfkill block bluetooth to /etc/rc.local. This did not work.

I tried adding both blacklist bluetooth and blacklist btusb to etc/modprobe.d/blacklist.conf. This did not work.

So I went to Synaptic to remove it altogether, but when I marked bluez for removal it said it was going to also remove gnome-shell as well! So naturally I didn't do that.

(Is it sane to run a potential security problem like bluetooth by default? And why is something like that so tightly integrated into Gnome shell?)

Can anyone tell me how to get rid of this annoying and unnecessary process?
