Intel Graphics Media Accelerator 4500MHD

This is an Intel video adapter

Features

  • Integrated into the following chipsets:
  • PCI ID: 8086:2a42
  • Uses part of main memory for video usage

Linux KMS

KMS (Kernel Mode Setting) is a recent development, and requires that you have at least kernel 2.6.31 and Intel Xorg driver version 2.8. But newer is better. With the 2.6.32 kernel and Intel Xorg driver 2.9 you can expect full functionality including external displays and 3D acceleration. However, Linux >=3.19 should be used because it includes a fix for a Graphics Corruption Bug.

X.Org driver User Mode Setting

NOTE!
UMS where the mode setting is done by the Xorg driver in user-land is deprecated and newer versions of the Intel Xorg driver (v2.10+) no longer support it. Instead you will have to use KMS (Kernel Mode Setting)

Make sure you're using Intel Xorg driver, version 2.8 or 2.9.

HD video acceleration

The hardware does support acceleration of video decoding, but it's not yet supported by X.Org's intel-gfx. Support was supposed to arrive in Q3 2010 via libva. There is already MPEG2 acceleration for this chip though.
