There are no alternate drivers you can or should install for Intel graphics. The drivers are built-in already, and will get automatic updates.

But ,the problem is : i can't control the brightness of my loptop screen and it doese not work for me !

OK, this bug has now been reopened to track that problem and assigned to the kernel.
