I've seen this question all around, but with no proper answer.
I have a Dell Inspiron N5110 and I'm using Ubuntu 11.10.
My Bluetooth is not working. I try to enable it, but but nothing happens. The icon of it on the top right corner seems on but when right-click and open preferences, and try to slide the bar to turn it on it's just not working.
P.S. It's very important because I have a Bluetooth Wacom pen tablet which I cannot use until this is fixed.
