Is there a way to do a screenshot of the rotating cube? I can't get it to work while I am rotating the cube.
Applications > Accessories > Take Screenshot
Where it says "Grab after a delay of [0 ] seconds" Change the delay to say 5 seconds, then go into the cube mode. Ctrl + Alt + Left Mouse Button, then hold it for 5 seconds.
When you return to a workspace you will see the screenshot window offering to save.
From the terminal drop:
Where: 10 is the amount of seconds you wish the screenshot to wait before be taken. You can change this value to any amount of time as you wish.
After hitting [Enter], do whatever you wish and wait for the screenshot to be taken.
