This question was marked as an exact duplicate of an existing question.

Which driver did you try to install? The nvidia binary blob from the official Nvidia site or did you use the Additional Drivers interface? Also which driver version did you try to install – Ciaran Liedeman Oct 26 '11 at 11:08
@Anarci he clearly specifies jokey – Bruno Pereira Oct 26 '11 at 14:59

Nvidia hybrid solutions are not supported by the current driver. You need to make further adjustments to make your system run with a hybrid solution. The most common and known to work is Bumblebee.

Bumblebee and your graphics card were already largely discussed here. Have a look.

Basic recommendation is stay away from hybrid, nvidia does not give driver support for linux on those yet!
