Cursor hangs in Ubuntu 11.04 - ( Tested Samsung Netbook N series)

Sometimes while you are working on your Ubuntu 11.04 the cursor might hang and there is no way to move it. Only restart might help.

Open Terminal: ALT+CTR+T

Type:
sudo synclient touchpadoff=0 (Enter)
type your password on prompt.

That's it your cursor is alive again!
(Note: 0 is to switch on and 1 is for switch off touch pad)
