I am using a Logitech Webcam Pro 9000 and Skype 18.104.22.168 and Ubuntu 11.04. I can not figure out how to zoom in and out during a video chat, although it is possible under windows using Logitech's software. Is this function supported under Skype and Ubuntu 11.04?
The old keyboard shortcut works for many programs; give it a try while you have Skype open:
From terminal you can try the video adjustment package that's listed as supported for your model:
sudo apt-get install guvcview
