I'm used to the desktop environments that were used in 9.0+ and 10.0+ series of Ubuntu. I cannot stand the 13.10 desktop environment. How do I get the old environments back?

Why I can't stand it:

1) Cannot right click on desktop
2) Annoying bar on the left side of screen
3) Cannot change features from right-clicking on desktop

etc. etc.

I want the old desktop environment back
