Switchdesk say KDE 2.0 is not istalled,though I have updated it from ftp.linux-easy.com. These file comes from Redhat.
The version of switchdesk that came with Red Hat Linux 7 looks for KDE 2.0 in /usr/lib/kde2, where the preview packages included on the second CD went. Workaround until I get to adapt switchdesk: ln -s /usr/bin/kicker /usr/bin/kpanel switchdesk KDE
Fixed in 3.7.
