Utility to take screenshots on console while graphics is displayed
There are many ways I can take screenshot of my virtual console (tty1) - using cat /dev/vcs1 or setterm -dump and all.
However I need to take screenshot of my consoles when a graphics is displayed. For example, when a 'dialog' box is displayed on tty1.
I am not able to find such a utility so far. I don't have X windows installed. I just have a very basic console based Debian system and I intended to keep it like that.
