I've applied the latest chipset update:
from acer.com to my Acer TravelMate 240.
The only video driver download I can find there is
But when run its setup it says it can't find any hardware to update, so as far as I can tell, I do have the latest video drivers. In any case why would that matter now when it doesn't for the other samples and didn’t for teapot on Panda3D-1.5.4?
