Disable Blueooth Gigabyte Ryzen Linux

For optimal security we will disable Bluetooth when Linux is starting up. We will add the following command in /etc/rc.local

rfkill block bluetooth

  Since as of Ubuntu 18.04 there is no longer a default /etc/rc.local file we must create one manually using the following command.

sudo nano /etc/rc.local

Now paste the following into the rc.local file which includes the rfkill block bluetooth command.

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

rfkill block bluetooth

exit 0

  Finally let's make it executable so it will run on system startup.

sudo nano /etc/rc.local

  That's it!  To test your configuration you can restart your system to ensure that bluetooh is no longer enabled by default by your system.     References: https://etechshout.com/disable-bluetooth-at-startup-on-linux/ https://forum.gigabyte.us/thread/6424/bluetooth-wifi-disabled-bios https://vpsfix.com/community/server-administration/no-etc-rc-local-file-on-ubuntu-18-04-heres-what-to-do/
