This is possible - I do it myself, but you will want to be sure that your user and group ids are the same on both systems. Not the name, but the id number.

Yes. As long as you created your user account(s) and group(s) in the same order, then Kubuntu and Ubuntu should have given you the same account and group ids. However, if you just wanted Kubuntu because it uses the KDE desktop, you could have installed that on Ubuntu after the basic installation, and select which desktop you prefer when you log in.

I dont know what you did but you can install kde desktop on ubuntu. Just run
sudo apt-get install kubuntu-desktop, then choose kubuntu from login screen.
