Intel GMA 4500MHD

Intel Graphics Media Accelerator 4500MHD This is an Intel video adapter Features Integrated into the following chipsets: Intel GM45 PCI ID: 8086:2a42 Uses part of main memory for video usage

Linux driver 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 kernel >=3.19 should be used because it includes a fix for a Graphics Corruption Bug.

Linux driver UMS

NOTE!

UMS (User Mode Setting) 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 acceleration

The hardware does support acceleration of HD decoding, but it's not yet supported by the Linux driver. Support was supposed to arrive in Q3 2010 via libva. There is already MPEG2 acceleration for this chip though.
