Title:
Bluetooth is disabled in gui, but audio reciever's action button still
controls Ubuntu
Status in bluez package in Ubuntu:
New
Status in linux package in Ubuntu:
Confirmed
Bug description:
Current behavior:
In gnome-control-center I see the Bluetooth slider is set to Off and the
status shows "Bluetooth Turned Off".
My Bluetooth audio receiver which had previously been paired can still
control VLC, or any other compatible media player with a Pause/Play
button. If no compatible app is running then an error icon
appears.[0]
Expected behavior: when gnome-control-center Bluetooth shows Disabled,
then no bluetooth device should be able to communicate with the
computer.
Security: This is way out of my wheelhouse, but if this goes beyond my
use case, could this have security implications? Just the fact that
the bluetooth subsystem is functional when the UI says it is not,
seems like a bad sign, correct?
EDIT: as a next step, when I enabled Bluetooth in gnome-control-
center I see the device's status as "Disconnected" and the device does
not appear as a possible sound output device in Sound settings. In
this Bluetooth enabled state, the pause/play button still works. When
I disable all Bluetooth, the pause/play button still works.
EDIT2:
I'm not sure what the gnome-control-center Bluetooth On/Off slider is
supposed to do, but while gnome-control-center Bluetooth shows disabled the
service is still running.
