I have a computer that I run Ubuntu on with that exact graphics chipset, and it runs flawlessly.
What kind of problems are you having? Why exactly do you mean by "it does not seem to be working."?
the problem is i cant utilize my graphics chipset to full potential,,
i.e the video plays a bit jittery,,,
i cannot use the special effects provided by ubuntu,,,
what to do???
