How to make screenshots silently.

1. Install imagemagick package: sudo aptitude install imagemagick
2. Save this script somewhere:
   #!/bin/sh
   
   file=~/Desktop/Screenshot.png
   if [ -f "$file" ]; then
   i=1
   file=~/Desktop/Screenshot-${i}.png
   while [ -f "$file" ]; do
   i=$(($i+1))
   file=~/Desktop/Screenshot-${i}.png
   done
   fi
   
   import -window root -display :0 +repage "$file"
   
3. Now make this script executable: chmod +x
4. Use Super+Print to launch this script - launch gconf-editor, go /apps/metacity. In global_keybindings choose free run_command_X (should be disabled), and set it to <Super>Print. Then go to keybinding_commands and set command_X (X should be the same as X in global_keybindings) to full path to the saved script
