The program says:

"No proprietary drivers are in use on this system"

But it doesn't say if it is talking about graphical drivers only or what.

Then, it lists two drivers:

NVIDIA accelerated graphics driver (version 173).
NVIDIA accelerated graphics driver (version current) [recomended]

Both have exactly the same description. What is the difference then?

1. When I select the 1st one, it says: "This river is not activated",and there's a button to "activate" it.
2. When I select the 2nd one, it says: "This river is activated but it is not currently in use", and the button is to "remove".

So which one is in use? Why or what for should I have activated (enabled) and not in use? If it is in use it is activated?

What is the difference between activate and remove? and what is the relationship between installed, activated, in use, enabled and removed, disabled, inactive and not-installed?
Why can I activate the inactivated and remove (but not deactivate) the activated that is not in use?

All this is very puzzling...

What other drivers can I use for an Apple MacBook pro 3,1 and how? I see that there's a nouveau and I heard that there was going to be a new open source even better.
