[Pkg-bluetooth-maintainers] Bug#471148: bluez-gnome: bluetooth-applet should allow to disable bluetooth

[Florian Lohoff]

Package: bluez-gnome
Version: 0.22-1

Hi,
in the are of extended mobility life it would be nice if the
bluetooth-applet would enable the user to switch off bluetooth
alltogether. Another nice thing would be to be able to configure an
idle timeout of the bluetooth e.g. after 10 Minuten of not discovering
new devices or without connection disable bluetooth until user requests
enabling. As interface configuration is a root only thing one would need
to utilize dbus for this ...

Bluetooth is currently the source of the most wakeups on my notebook
(Fujitsu Siemens Lifebook E8110) and i can only disable it by opening
a terminal and issueing a "sudo hciconfig hci0 down" which is not really
a solution for Aunt Tilly ...

Top causes for wakeups:
  85.7% (953.0)   /sys/bus/usb/devices/4-2 
   9.0% (100.0)       <interrupt> : uhci_hcd:usb4, ohci1394, yenta, yenta, sdhci:

   0.1% (  1.0)    cpufreq-applet : schedule_timeout (process_timeout)

Issueing a hciconfig hci0 down shows this in powertop:
