Why keeping BT apps and daemon on a device not having any BT extension board?useless.
so here is what i found about :
If you want to disable BT at boot-time, you only have to blacklist the bluetooth module (=driver) in order to prevent the kernel from loading it on reboot.
sudo echo "blacklist bluetooth" > /etc/modprobe.d/blacklist-BT.conf
Then you can purge most of the Bluetooth-oriented packages (a few libs cannot be removed since it would completely uninstall some essential parts of your DE and/or destroy it).
On a working bluetooth-enabled system you should have something like these results
$ lsmod|grep blu
bluetooth 147960 24 bnep,btusb,rfcomm
rfkill 13361 2 bluetooth
crc16 1288 2 ext4,bluetooth
and if BT is disabled, "lsmod|grep blu" will return no result.
that is exactly what i did, then i removed the following packages :
- gnome-bluetooth (that removed gnome-user-share due to dependency)
Seems everything ok now
