When I press printscreen (same with gnome-screenshot --interactive) all I get saved into my Pictures folder is the desktop background image. If I use shift printscreen to capture just a rectangle then I get the background part that is under the rectange I specify. The windows on my desktop do not appear in the screenshots.
I don't know much about X and root windows but I know there are ways to specify different displays, is there a way to tell the screenshot program what X window display screen to use? Or any other ideas? Where is the screenshot program, and how is it tied to the printscreen key? I found in system settings how to change the key assignments to the screengrab program, how can I assign what screengrab program is used and it's parameters?
