well, the title says it all...
I´ve heard of edubuntu desktop, and I think it´ll be very usefull for my child, so the point is can both desktops live together?
thanks in advance
If you can install it like @Daniel recommends, "Try
sudo apt-get install --install-recommends kubuntu-desktop edubuntu-desktop
Then it should be available to be selected on your login screen where you can choose between Kubuntu and Edubuntu; by selecting the wheel next to the password box.
sudo apt-get install --install-recommends kubuntu-desktop edubuntu-desktop
