The ability to take screenshots in Linux is something that I find really useful when composing how-tos and training materials for students or readers. But there are many different ways to do this.
My own personal favorite is Gnome Screenshot. Typically I use Linux on a desktop or laptop and the training materials even those on those that feature the command line can be easily captured by Gnome Screenshot. I like it because it provides some options that make later use of those screen grabs easy to use. The need for additional editing of the screen grabs is precluded when you can easily tailor each screen grab to exactly what you are trying to capture. Your options include grabbing the whole screen, grabbing just the current window, or selecting an area to grab. Screenshot also provides an option to time the delay of the screen grab.
But my favorite isn't necessarily the same as yours, and you may not even use Gnome at all. What is your favorite Linux screen capture tool, and why do you like it?
