just got a question on the plasma shell. I was checking out some of the background pics for the desktop and someway I switched over to the plasma screen and I want to revert back. I lost all my Icons on the screen for all 6 desktop enviorments that is why I don't want the plasma theme. I went back in and tried to put in the oxygen theme but it will not go.
This is a bit hard to decipher. If you are running KDE you probably have a plasma desktop. Unfortunately the word "plasma" means something entirely different in that context than when we talk about plasma monitors.
I think - but this is a guess - that you have simply changed the layout of your desktop from "Folder View" to "Default Desktop", or vice versa. In that case, just right-click your desktop, click "Folder View Settings" or "Default Desktop Settings" and change the layout to the other one.
By default you actually have six layouts to chose between, but "Folder View" is the most popular one, followed by the "Default Desktop". If your icons disappeared you probably switched from folder view to something else - or you may have changed the "Location" of the folder pointed to by your folder view.
