Public bug reported:
On Live and on Install the screen resolution is too low.
On Edgy on the same hardware the nvidia card displays at 1280x1024 and
3d acceleration works well.
On Feisty the resolution defaults to 800x600 which is the maximum
resolution that the "screen resolution" dialogue lets you choose. 3d
acceleration does not work at all.
Here is the relevant sections of xorg.conf on Edgy:
