sudo apt-get install kdm-kde4

When installing the package, it should ask you what default kdm to
use.  I chose the new one and upon restarting, couldn't log in.  You
may want to try the new one to see if it will work.  If you try
kdm-kde4 and it doesn't work then you should restart in recovery mode
and type this in your shell:

sudo apt-get remove kdm-kde4
sudo apt-get install kdm-kde4

When given the option to choose which default kdm to use, choose "kdm"
and not "kdm-kde4".  User switching and screen locking is working for
me without kdm-kde4 being the default.

HTH,
Andrew
