OK, then this is seriously weird.

In your "kdmrc" file ($KDEDIR/share/config/kdm/kdmrc) you should find a 
line key: "SessionsDirs=".  This should point to the directory where the 
'desktop' files for the session types are located.  The default is: 
""$KDEDIR/share/apps/kdm/sessions", but yours might be different.  In 
the directory you should find a file: kde.desktop.  If that file exists, 
it should be correct but you can check the first few lines which should be:

	[Desktop Entry]
	Encoding=UTF-8
	Type=XSession
	Exec=startkde
	TryExec=startkde
	Name=KDE

Specifically, does it have: "TryExec=".  If it does, this is the mystery 
since this wouldn't appear in the menu if the script: "startkde" wasn't 
available.

But, IAC, the script: "startkde" must be on your path.  So, from a 
console (not in the Xsession) execute:

	which startkde

If it doesn't find it, then you have a path issue.

And, as a temporary measure, open your $KDEDIR/share/config/kdm/Xsession 
file in an editor.  The end of this should be:

case $session in
   "")
     exec xmessage -center -buttons OK:0 -default OK "Sorry, 
$DESKTOP_SESSION is no valid session."
     ;;
   failsafe)
     exec xterm -geometry 80x24-0-0
     ;;
   custom)
     exec $HOME/.xsession
     ;;
   default)
     exec /usr/kde3-unstable/bin/startkde
     ;;
   *)
     eval exec "$session"
     ;;
esac
exec xmessage -center -buttons OK:0 -default OK "Sorry, cannot execute \
$session. Check $DESKTOP_SESSION.desktop."

{your paths will be different}

unless your distro changed it.  Actually, I suspect that you file must 
be different.  Put this line:

     exec /usr/kde3-unstable/bin/startkde

{with your path}

before the: "case" and see if it starts KDE.
