Just before typing the shell command line you posted above, try this:

Code:

export DISPLAY=:0.0

Hope this helps.

This is how I have done it.

Code:

xwd -display :0 -root >image.xwd
convert image.xwd image.png

Perhaps you are trying from a console ( very black ) and not a terminal in kde as I was.
In that case, this works on my system...

Code:

setterm -dump 2-NR-CONSOLES 
cat screen.dump

You could also have a look at the command: script
The ouput is saved in a file called typescript
Use ctrl d to end the capture
