apparently unity needs compiz-core to run, but it does not require it on its dependencies and it is not installed by default on a kubuntu-desktop machine.
2) add 'export GDMSESSION="$DESKTOP_SESSION" ' on top of /etc/kde4/kdm/Xsession
this is executed by kdm at user's login and fixes the environment variable issue.
This worked perfectly for me and I hope can help all KDE fans to enjoy the brand new, and much discussed, user interface.
By the way can "$DESKTOP_SESSION" be a candidate for a DM independent variable?
This is how I managed to start unity from KDM:
1) aptitude install unity compiz-gnome
