How to restore panels in Ubuntu to their default settings after maybe deleting the Panels or accidentally removed an icon or something? You could always add the Panels/Icons one by one, but that’s time consuming. The quickest answer is below.
Start a Terminal session. To do this press ALT+F2 together. The Run Applicationwindow should appear.Type in “gnome-terminal” click on Show list of known applications and select Terminal and click on run.
The Terminal window should be open now.
Enter the following command “gconftool –recursive-unset /apps/panel” and hit Enter.
After the previous command executed successfully type in the following command “pkill gnome-panel” and hit Enter.
All Panels top and bottom should appear. Or the missing panel will appear again. Customize them to you’re previous settings.
