Hi,
I think it is hybrid graphics, that is it works on Ati and Intel too.
In the BIOS there is no integrated or discreet feature in the gpu section.
I tried writing xmodule=ati and xodule=intel, but nothing happened -- the xserver didn't want to start.
Gentoo wiki is too specialized for me to understand. I had downloaded the Gentoo Live DVD and found out it is quite nice, but there is no way to install it, so I downloaded Toorox, which doesn't work. I am downloading Sabayon 6, as Sabayon 5 worked very well.
Wish the Gentoo people add a installer for their excellent Live DVD...
