Unlike GNOME’s panels and panel applets, KDE 4.0’s plasma widgets don’t have to be placed in a panel. In fact, you don’t need to have a panel at all. Here’s how to remove the bottom panel in KDE 4.0:
- Browse to ~/.kde4/share/config/ and make a backup copy of of the plasma-appletsrc file. This is the file you will need to edit. You can use the backup to restore the panel and your widgets to their previous configuration.
