The last time I checked, the only way to benefit from HD-3000 is to return to Windows 7 and use the Intel drivers. As I recall, Intel does not support drivers for Linux.
Got advice to install the package xserver-xorg-video-intel. It's already part of Ubuntu 11.10.
The package description talks about the Intel i8xx and i9xx family of chipsets up to i965 series chips.
It does not mention the CPU-integrated HD2000 and HD3000 graphics.
So I'm not sure whether xserver-xorg-video-intel gets the most possible out of HD3000.
In doubt, probably not.
Signed up to say I installed the driver from the site you (CarWiz) posted and it works fine.
I have an Intel HD 3000 by the way.
Just thought I'd post that! Take care!
