hi,all

My nivida is GT 425M,and I downloaded the driver from
http://www.nvidia.com/object/linux-d...12-driver.html<http://www.nvidia.com/object/linux-display-amd64-260.19.12-driver.html>.
(the installer log is in the attachment )

However,it doesn't work.

The following is the result of "lspci | grep VGA" (It has 2 graphic cards,
and I think that's the problem,but how to deal with it?)

00:02.0 VGA compatible controller: Intel Corporation Arrandale Integrated
Graphics Controller (rev 18)
01:00.0 VGA compatible controller: nVidia Corporation Device 0df0 (rev a1)

I've tried the method in http://www.x.org/wiki/NVIDIAProprietaryDriver, it
doesn't work either.


My file xorg.conf  , /var/log/Xlog.0.log and error message are in attachment
too.

Thanks in advance.
