My laptop is ASUS's X44H, with Intel® Core™ i3-2350M CPU @ 2.30GHz × 4 , and AMD's graphics card RADEON HD 7470M. How I will install my graphics Driver.
You could try to use the default drivers that come with the distro. Go to "Software & Updates" and under the tab "Additional Drivers" you'll find them.
