How do I take a screenshot on a Raspberry Pi running Debian Squeeze and LXDE?
Noob question...
But shutter not installed, print screen doesn't appear to work, screen grab not installed etc.
Answer
This can be achieved with ImageMagick. Install by running the command
sudo apt-get install imagemagick
To grab all desktop just type
import -window root screen.png
Or you can do it with a delay of 5 seconds
sleep 5; import -window root screen.png
