Graphics driver for VAIO laptop

A few days ago I requested help to configure windows settings and animations, because of the absence of compiz on Unity. Question 204881 was promptly answered, which resulted on installing My Unity. I was expecting to get my wobbly windows and the like, but it didn't happen. I checked the driver installed by Ubuntu: Details > Graphics and I obtained Diver = Unknown, Experience =Standard. I assume that this says that the OS installed a default driver for my laptop. I checked if the graphics hardware was recognized and, yes it was as follows.

Are there any particular graphics driver in the repositories that would work with the above graphics card?
Thanks.
