I have an Acer Aspire 4810T with ubuntu 10.04 installed on it.
Fn+F3 should turn on/off the internal bluetooth receiver. But it does nothing. The "bluetooth" menu in System > Preferences says "your computer does not have any bluetooth adapters plugged in". I have
bluez-utils installed. Other people have reported that bluetooth works out of the box on the timeline series of laptops with ubuntu. (Although others say that upgrading to a newer version of ubuntu rather than doing a fresh install can break things...)
Various things I've read on forums that it is suggested I try have failed.
hcitool dev gave an empty output (Just a line that said "Devices" and nothing else.)
hciconfig finished with no output.
lshw | grep Bluetooth -A15 also finished with no output.
I'm not sure what the next step is in diagnosing what the problem is. What can I do now to figure out where the problem is?
