This script changes the cursor in ubuntu 10.04, there is a problem because if you change the cursor only with gconf-editor, you will have double-cursor.
Download a cursor, extract and paste the carpet in /home/user/.icons.
First, open the script with gedit and where it says "new_cursor" we replace with the name of the new cursor with quotes, where says old_cursor, 2 options, if you never have changed you replace with DMZ-White, if you have changed the cursor you must put the name of this cursor, and where it say new_cursor, replace without quotes.
Second, we give execution permission and execute, run in terminal, when it need your password, you type it.
Next, restart or restart desktop.
Example in screenshot 2.
