I see another post on this, but no answers, so I'll give it a shot too. Since I upgraded from RH9 to FC1 with no KDE problems, then FC1 to FC2, my KDE menus are completely empty, KControl has no preference modules listed, if I try something like "kcmshell background" it doesn't do anything. Strace'ing the execution of kcmshell doesn't show me anything interesting. I even yum remove'd kdebase and put all that it removed back on, just in case there was something weird there, no joy. Then I went into /usr/lib/kde3 and moved everything that wasn't obviously part of the new version, no change. I also created a new user and tried it out, same deal. Not sure what else to try. :-/ There do not seem to be an errors, no complaints from kcmshell/kcontrol, etc, it's like the stuff isn't there at all. Thanks.
