I installed KDE to see if it's better than Unity. I didn't like it, so I uninstalled it, but now, when I boot in Ubuntu, it just goes to command line, asking for a user and password. How can I get it to the "default" state that used the Unity GUI?

Kubuntu has its own display manager KDM. Ubuntu uses Lightdm as its sdisplay manager. It seems that your system doesn't know anymore that it has to use Lightdm as its display manager.– user85164Nov 8, 2013 at 0:58

Try this at cli after login,
sudo service lightdm start
If it solves your issues. Open a terminal to edit the file /etc/X11/default-display-manager
as
sudo gedit /etc/X11/default-display-manager
Add the following line there,
/usr/bin/lightdm
or
/usr/sbin/lightdm
after this lightdm
should start normally on reboot and bring you to the logon screen as usual.
