How to restore the top panel to initial state in Ubuntu

Sometimes, we may accidentally put all of the top panel to delete all the stuff, but also found that the tool added to the panel can not be added, this time, we can actually restore the upper panel to the original value:

1, press the ALT+F2, enter the following content and press ENTER

Gconftool--recursive-unset/apps/panel

2, press the ALT+F2 again, enter the following content and press ENTER

RM-RF ~/.gconf/apps/panel

3, you have to do another alt+f2, and then enter the following and press ENTER

Pkill Gnome-panel

OK, finish the work ~

Look, the panel has been restored to its original state.
