[Bug 913736] Re: Thinkpad 410s -- Cannot re-enable Bluetooth after it's been disabled

 

apport information

** Tags added: apport-collected oneiric running-unity

** Description changed:

  During UDS-P I was experimenting with various settings to reduce power
  consumption on my Lenonvo Thinkpad 410s.
  
  I turned Bluetooth off via the System Settings - Bluetooth panel.  I
  also removed the icon from the panel by turning visibility to Off.
  This all works great except for the simple fact that I cannot re-enable
  my Bluetooth anymore.
  
  When I re-launch System Settings - Bluetooth, both toggle switches are
  "Off", and the left hand column below includes the text "No Bluetooth
  Adapters found".   There seems to be no way to re-enable my Bluetooth
  now as both switches are disabled and grayed out.
  
  I believe this is due to the fact that when BT is disabled, the device
  disappears from the bus, which leaves nothing for the code to grab in
  order to re-enable the device.  This is a guess on my part, as I haven't
  yet taken a look at the code...
  
  My machine is running 11.10 with all of the latest updates.
  
  The version of gnome-control-center on my machine is:
