I'm running Lubuntu 13.04 on an Acer netbook A105. I have installed Skype 4.2 on it. Though I can see my webcam working in my video settings, but I can't initiate or join a video call with my video on. I can see the other person's video, but I'm unable to turn on my webcam. If I do install other applications that use my webcam like Google Hangouts it works. It doesn't work only in Skype. I want to fix that.
