It's not an nvidia as far as I know. H-Node says it's Intel:
Intel Corporation Atom Processor D2xxx/N2xxx Integrated Graphics Controller (rev 09) (works, but without 3D acceleration)
(http://h-node.org/notebooks/view/en/651/Eee-PC-X101CH)The system details show "Graphics: Unknown". Is there a way to force the intel driver?
