The easiest way is to use LUKS encryption, which you can choose when you install Ubuntu if you use the alternate (not Live) CD. It's considerably more difficult to setup after installation. I prefer LUKS to using encrypted home directories for single-user systems, but each method has its advantages and disadvantages.

If you're familiar with and like TrueCrypt it is available for Linux as well. I haven't actually used it for whole disk/partition encryption, but I have for files and it works for that.

LUKS is definitely the more standard/integrated Ubuntu way to encrypt, but I'll agree it's not the easiest thing to set up post-install.
