[GTALUG] How to install Intel HD Graphics driver?

[William Park]

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.
