If you're running Kubuntu and decide you want to change to Ubuntu (i.e. use the Gnome desktop rather than KDE (which is better in my opinion)) all you need to do is to go to the shell and enter:
sudo apt-get install ubuntu-desktop
You will now have to wait some time for all the Gnome apps to download and them some time for Kubuntu to get everything set up. Once that's done though all you need to do is log out and then log in and choose Gnome as the session type.
You'll now have Gnome and KDE installed which means you'll have two lots of applications for many areas (e.g. you'll have two text editors, Kate and gEdit). This is fine and won't cause you any problems. However, you may wish to remove some of these applications through the package manager if you don't want them.
If you want to get rid of KDE enter the following in the shell:
sudo apt-get remove kubuntu-desktop
If you do remove kubuntu-desktop and then find you have trouble using themes in Gnome go to the shell and enter:
switch2
Then choose your style from the dropdown; gneom-theme-manager should work fine from thereon.
