Under System/Preferences/Startup Applications, is the Bluetooth Manager checked off?
Do you see the bluetooth symbol in the task bar?

Bluetooth manager is checked on,but I can't see bluetooth symbol in the task bar.

Start a terminal
control alt t
and type:
dmesg |fgrep -i blue

You should see about a dozen lines of bluetooth initialization. paste what you see into your next message

You should have the bluetoothd daemon running, and the bluetooth-applet
ps auxww | fgrep blue
If they are not running, try starting them directly
sudo /usr/sbin/bluetoothd
sudo /usr/bin/bluetooth-applet

If that fixes things, you may be missing the /etc/init/bluetooth and the /etc/rc2.d/S25bluetooth link to the init.d file

Maybe the bluez package did not get installed?
Getting late here, signing off for tonight.
Good luck

Dear Ubfan,
I can use my bluetooth mouse by using external bluetooth dongle.But while using Windows 7,no need of that.


What windows does or doesn't do is of no value at all, its a differentOS with different support, so replying with what windows does doesn't help your issue.

If you install bluez then reboot it may help, you will need to press ALT+F2 then type:


then WAIT, suggestions for apps will appear, run which sounds most intelligent (or you can give us the list and we can choose for you).

biji (bijimathew007) said : #8

Dear actionparsnip
I got apps 1)BlueWho and 2) Cube
so I think bluez not get installed properly.
what 2 do next and how?



Install bluez using software-centre or apt-get would be a good guess, thought that one would be obvious. Install it. Then try ALT+F2 again. You should now have new options.

I have installed Bluez and Blueman manager again,but still i could not find anything significant when I try Alt + F2
The following message I got when I clicked bluetooth icon in the panel
"Connection to BlueZ failed
Bluez daemon is not running, blueman-manager cannot continue".
what 2 do next?


Ubfan (ubfan1) said : #11

You can run the bluetoothd yourself, see above post.
  You apparently have multiple bluetooth managing packages installed and they are interferring with each other. bluez and gnome-bluetooth might be all you need -- they should pull in the rest at install time. blueman, BlueWho, ... ??? try getting rid of these extra ones with
sudo apt-get purge blueman
The /etc/init.d/bluetooth should start the bluetoothd, but after installing blueman, I don't know what it does now.
The system/administration/synaptic package manager tags the Ubuntu approved packages with the ubuntu symbol, start with those packages unless you have a specific reason for using another.

Can you help with this problem?
