How to remove top panel Ubuntu

I have got this problem when I tried to put one more panel on the top panel and set it to auto hide, it went into infinite loop and thus my top panel also stopped working.

This is the bug of Ubuntu and if you have the same problem then do the following steps:

1. Go to terminal, I know your ALT+F2 is not working, try using CTRL+ALT+F3
2. Find the toplevel directory where all the panel information stores
   Code: locate toplevels
3. Go to toplevel directory
   Code: cd /home/username/.gconf/apps/panel/toplevels
4. Go back one step
   Code: cd ..
5. Rename the toplevel directory
   Code: mv toplevels toplevels_old
6. Log Off the panel and login again
   Code: sudo service gdm restart
7. Now all your panel comes, remove/change the extra panel from top or bottom
8. Restore the toplevel directory (Go to the directory again)
   Code: mv toplevels_old toplevels
9. Problem is Solved :) :)

 Hope this wont take much time to resolve the problem. Let me know in case of any confusion :)
