[GTALUG] How to install Intel HD Graphics driver?

For NVidia cards, I just download/install NVIDIA-Linux-x86_64-aaa.bb-no-compat32.run It's one file, and it's easy. To run mplayer with VDPAU, I just set vo=vdpau in the configuration file. I assume it's the same for AMD cards. I don't have AMD cards, so don't know. For those with Intel HD Graphics, how do you download/install driver? I went to Intel site, and it's utterly confusing. I just want Intel's driver, so I can try out VAAPI. -- William
