So far, when I try to make a video call with Skype, it works fine for a few minutes, then freezes, then my whole system crashes. I've got Ubuntu 10.10 (and also Windoze 7) on a Gateway NV53 laptop, AMD 64-bit, built-in webcam (Cheese works fine), USB mic (Audacity works fine), and Skype version 2.1.0.81 (Beta) (skype works fine under windows). Any tips will be appreciated; I need to get this up and running in order to set up online (math) tutoring. Thanks.
