the CPU usage of my openSUSE VM seemed abusive, elimated “Nepomuk Semantic Desktop”

I don’t think, I do make the intended use of the Nepomuk Semantic Desktop, so I prefer to switch the entire thing off.

I couldn’t find the cause through “top”, but “pstree -p” showed a lot of processes with “nepomuk” in their names. A KDE search (KDE Start button, “Search”) for “nepomuk” helped.
“Nepomuk Server Configuration“, toggled “Enabe Nepomuk Semantic Desktop“.

Right, maybe I switched exactly off: the KDE search. Well, how bad! But I simply don’t like any such thing (“desktop search pre-indexing”) beyond the UNIX locatedb. I like it “cheap” and lightweight.
