su is not enabled by default on Ubuntu.
sudo is, however.
When you want to execute a command as super user you do:
sudo <command>

If you want to open a program as superuser (which, you rarely do):
gksudo <command>

for example, this opens the program "nvidia-settings" as super user:
gksudo nvidia-settings

Ubuntu uses "sudo", while other distros, like Fedora might be set to use 
"su", by default.
