Since I got my X40 back in April, I have always wondered if it had Bluetooth. On the underside it has a label for the bluetooth device, but I couldn't find it. I would run a lspci and I just couldn't identify it.
So the other day I was searching the net and ran across thinkwiki which has alsorts of interesting information. One piece of information was how to activate the bluetooth. Just press fn F5 and this enables the bluetooth under ubuntu linux.
It works really great, and I just need to make some changes to the ubuntu acpi network scripts so that I can cycle through the wire-less networks so I can have 1 turned on and the other not.
Thinkwiki is a great resource, Thanks.
