3) Type this in a console as root
urpmi.addmedia main ftp://anorien.csc.warwick.ac.uk/Mandrakelinux/official/10.1/i586/media/main with media_info/synthesis.hdlist.cz
urpmi.addmedia contrib ftp://anorien.csc.warwick.ac.uk/Mandrakelinux/official/10.1/i586/media/contrib with media_info/synthesis.hdlist.cz
urpmi.addmedia jpackage ftp://anorien.csc.warwick.ac.uk/Mandrakelinux/official/10.1/i586/media/jpackage with media_info/synthesis.hdlist.cz
urpmi.addmedia plf-free ftp://ftp.planetmirror.com/pub/plf/mandrake/free/10.1 with synthesis.hdlist.cz
urpmi.addmedia plf-nonfree ftp://ftp.planetmirror.com/pub/plf/mandrake/non-free/10.1 with synthesis.hdlist.cz
urpmi.addmedia --update updates ftp://anorien.csc.warwick.ac.uk/Mandrakelinux/official/updates/10.1/main_updates/ with media_info/synthesis.hdlist.cz
then type
urpmi kdebase
that will definately install KDE
but there is absolutely no reason for KDE to not install in the firstplace.
I hope you all downloaded Mandrake 10.1 Official and not Community?
Another Option is if you have a day to spare compile KDE 3.4.0
1) http://developer.kde.org/build/konstruct/stable/konstruct-stable.tar.bz2
2) extract konstruct
3) browse to konstruct/misc/detektive
4) make (you are now told what your system is missing type urpmi and missing rpms one at a time)
5) browse to konstruct/meta/kde
6) make; make install (takes 12+ hours on 1 ghz machine)
once finished it puts kde in /home/'your username'/KDE3.4 so change to it
7) cd /home/KDE3.4/
8) ./startkde
i dont know how to make KDE 3.4 start on boot other then make a link for all KDE files to where Mandrake installed 3.2.3 (/usr/bin and usr/lib) so if someone knows please share
