I have no idea how to make it work? Any help for a linux newbie?

T61 14'' wide
Ubuntu 11.10

Welcome to the forum! If I remember well, you can install Skype, which supports the camera. I think I made it work when I had an Ubuntu Distro in my T61

Hi!

Unfortunately it doesn't help, 'no devices found' in skype cam options.

Could you post the model number of your T61? It's a 7 digit number that can be found in the bottom of the notebook, something like 6938-A31 (random example)

It's 7661-CT0

Those CTO models don't give us the info we're looking for. Check on the first page of the BIOS and give us the first 7 characters of the serial number.
