I don't know why I've got what looks like two different bluetooth managers running. From the details, it appears that both blueman and bluez are active.

Are both of these necessary, or can I remove one of them?

Here are the running processes:

$ pgrep -fl blue
1155 /usr/sbin/bluetoothd
3624 /usr/bin/python /usr/bin/blueman-applet

And the packages they apparently derive from:

$ dpkg -S  blueman-applet
blueman: /usr/share/dbus-1/services/blueman-applet.service
blueman: /usr/share/man/man1/blueman-applet.1.gz
blueman: /usr/bin/blueman-applet
$ dpkg -S  bluetoothd
bluez: /usr/sbin/bluetoothd
bluez: /usr/share/man/man8/bluetoothd.8.gz

I believe that blueman was installed (redundantly) when I added one of the several alternate desktop managers or environments (Kubuntu, Xubuntu, Lubuntu, etc.).

More importantly, I was able to remove all of the blueman packages, and everything still functions. On the upgrade to 12.10, I didn't have any issues with it re-appearing.
