How to Remove Bluetooth Manager in Xubuntu
Solution 1:
The following shell command will remove bluetooth and all its dependencies:
sudo apt-get purge "bluez*"
If this prompts you to remove the xubuntu-desktop meta-package, do not be alarmed. This is acceptable.
If installed, also remove the obex-data-server and the libopenobex package. The libbluetooth* package(s) must remain since too many stuff depends on it.
Afterwards, you should also run:
sudo apt-get autoremove
