I can do many things with the greatest of ease on the Linux desktop. But, as I discovered while doing my community Linux overview, recording a Linux desktop video isn't one of them. Oh, boy, is it ever not one of them.
My first problem was that I'd never done screen video recording before on any platform. I'd heard about Windows screen recorders such as TechSmith's Camtasia Studio and Blueberry Software's BB FlashBack, but I hadn't heard of an equivalent program for Linux.
