I've just installed 11.10 and so far so great, except I just discovered (after looking at another installation) I'm missing some effects.

First of all, I am using unity 3d (I chose ubuntu at the login menu), and have already the correct nvidia drivers. Yet, my launcher is the same from unity 2d, the same as the app switcher, and when dragging windows to screen corners, they don't get grabbed.

This "error" was present since the begining, so I was not able to detect it.

Please help, I want to have an ubuntu experience as nice as everyone else.

EDIT 1:

I'm using an Asus N53S. My graphic card is Nvidia geforce GT540M. It says cuda, if that matters.
