How can I split the standard Ubuntu terminal?
Solution 1:
Not with the standard terminal. There are, however, a number of applications that you can install that will extend your terminal to allow for it, called multiplexers. Tmux and Screen are two of the most common.
Solution 2:
Use terminator / termssh
apt-get install terminator # for GNOME but works fine on KDE.
