Bluetooth is disabled in 11.04

Try to do this:

1. Remove the bluetooth from the computer if it is an usb device
2. Open a terminal by hitting CTRL + ALT + T
3. Enter this commands:
sudo /etc/init.d/bluetooth stop
sudo /etc/init.d/bluetooth start

4. Then try to use bluetooth

If this not work try to do this:
1. In terminal run this:
sudo /etc/init.d/bluetooth stop

2. Start the bluetooth with the graphical way.

Issue solved by running "bluetooth-wizard" in Terminal, Bluetooth immediately changed from greyed out to active and options appeared in the menu that were not there before.

Thank you so much for your help.

I'm also having the same problem but is not resolved by the bluetooth-wizard (the wizrd keep searching forever).
I'm running Ubuntu 11.04 (kernel 2.6.38-11-generic) 64 bit on a Dell XPS l502x.
When I try to start the bluetoothd with parameters -nd I receive the following error:

i have the same issue on a sony vaio vpceh with a builtin foxconn hai bluetooth adapter.

Is bluetooth working for somebody using foxconn adapter?

Sony VAIO VPCEH with ubuntu 11.10 64bit also has this bug :(
