Xorg 说“无法打开模块 intel”，但 intel_drv.so 存在

在我的中Xorg.0.log有这些行：

[ 36753.331] (II) LoadModule: "intel"
[ 36753.331] (WW) Warning, couldn't open module intel

和

[ 36753.331] (II) LoadModule: "radeon"
[ 36753.331] (II) Loading /usr/lib/xorg/modules/drivers/radeon_drv.so

问题是 和 都intel_drv.so存在radeon_drv.so，但只有其中之一成功加载：

[c4thewin@LenovoG500-C4tW ~]$ ls /usr/lib/xorg/modules/drivers
ati_drv.so  fbdev_drv.so  intel_drv.so  modesetting_drv.so  radeon_drv.so  vesa_drv.so

我还读到modprobe需要.ko库作为参数，所以......

这不是modprobe幕后操纵的吗？
为什么intel_drv.so存在却无法加载？
