hey guys i have the latest ubuntu OS on my Acer 6920, which has built in bluetooth, but when i go to the System>preferences>bluetooth, it tells me that no bluetooth adapter is plugged in. (the bluetooth is internal and works in vista, so no, it is not a wiring problem.) what kind of software or firmware do i need to update my ubuntu into realizing that bluetooth is there? other people say it works on their laptops (same kind as mine) so i dont know what i need.
