Try, in order:
   urpmi.update -a
   urpmi trinity-korn
   urpmi trinity-desktop

  That worked fine, and I have now a TDE option at Login, and have tried 
a TDE session.

My first job was to adjust selection by mouse to a single click.
OK - so in Settings/Input/Mouse I set Single click and hit 'Apply'.
   But although single-click works on icons in the Panel, it doesn't 
work for desktop icons that are 'links to applications', e.g. Konqueror 
opening some directory. How does one achieve that?

Then I inserted a copy of my Mandriva kmail (1.13.5) 
~/.kde4/share/apps/kmail/mail directory into TDE's 
~/.kde/share/apps/kmail, but TDE's kmail (1.9.10) seems to ignore it.
  Isn't that where TDE kmail expects to find it?

(I was expecting to be slightly lost in a new distro, so it's probably 
something I've missed or misunderstood...)
