could not open the device /dev/nvidia0

我的机器是联想Y460，有双显卡
(下面是lspci | grep VGA 的结果：
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) )

nvidia 的显卡驱动是从官网上下的：http://www.nvidia.com/object/linux-d...12-driver.html

安装完成后，运行startx，出现错误 could not open the device /dev/nvidia0 （我尝试了http://www.x.org/wiki/NVIDIAProprietaryDriver中的方法依然不行）
错误信息输出:

我觉得是双显卡的问题，我用通用驱动vesa的时候可以进入x windows

附近中有我的xorg.conf , nvidia.installer.log , /var/log/Xorg.o.log

请问怎么解决，非常感谢！

你在用gentoo的话，也需要自己从官网上下驱动？

好像nvidia-drivers 不支持GT 425M，所以我从官网上下了一个~

nvidia-drivers就是nv提供的驱动，就是从 http://www.nvidia.com/ 上下的。

如果你想装260.19.12，你自己unmask就行了。
