To disable bluetooth service on startup

sudo nano /etc/rc.local

add this line before exit 0

rfkill block bluetooth

Unfortunately I don't know what to do after adding the last code, In other words how can I save changes? – Muhammed Feb 13 '14 at 10:35
    
Press ctrl+x and ctrl+s to save your change. This script is running each time you turn on the computer. So this line will turn off the bluetooth – jhilmer Feb 14 '14 at 15:58
    
To save is actually Ctrl+O (the letter, not zero) – Nathan J. Brauer Aug 21 '14 at 22:13
    
You can also use gedit to do this, if you are not comfortable with nano :) – Awal Garg Nov 27 '14 at 8:58

Following the answer here, what worked for me (in Ubuntu 14.04) was

sudo gedit /etc/bluetooth/main.conf
InitiallyPowered = true     # keep it that way
# add the following:
# start bluetooth on boot?
# compatibility note: if this variable is _not_ found bluetooth will start
BLUETOOTH_ENABLED=0

Save the file and reboot.
