How can I use Bluetooth in Ubuntu 11.04?
When I opened Bluetooth preferences ,I get a message like"No Bluetooth adapters present" and also It gives me
Your computer does not have any Bluetooth adapters plugged in
If I click "Receive files" option, I get "Personal File Sharing Preferences" dialog box. In that I get the following...
This feature cannot be enabled because the required packages are not installed on your system
Also I have "Share files over the Network" option locked.
Can anyone suggest a way to get the required packages?

lspciorlsusband look for relevant bluetooth adapters in your system. If possible copy and paste the lines in to your question. – Bruno Pereira♦ Jul 4 '12 at 13:46
