Unity works perfectly fine on my Dell E6400 (Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) == Intel GMA 4500MHD?) when run from Live-CD.
However it doesn't work on my 11.04 which was upgraded from 9.10->10.04->10.10.
What might be broken/misconfigured? Is there any "trick" I can enable 3D acceleration without reinstalling complete system?
Edit:
Unity support test gives following output:
