Well, for disabling the kernel module, you can blacklist it to not
load at boot time.

lsmod | grep bluetooth - This will give you the bluetooth module and the
other modules that require it. For me the output is:
bluetooth             179900  23 rfcomm,bnep,btusb

You will have to blacklist these modules in /etc/modprobe.d/blacklist
So add the following lines to /etc/modprobe.d/blacklist file:

blacklist rfcomm
blacklist bnep
blacklist btusb
blacklist bluetooth

And reboot. After the reboot you can check lsmod | grep bluetooth to
see if it is loaded or not, if it returns empty then it's not loaded.

As for the bluetooth related packages, I'm not sure maybe someone else
can point out the relevant packages specific to Lubuntu as I have a
lot of other packages installed as well, I believe removing bluez and
bluetooth should do it.

Hope this helps, cheers :)
