X failed to start

[houkensjtu]

I installed the xorg-sever to my thinkpad W530 according to here:
http://wiki.gentoo.org/wiki/Xorg/Configuration#Kernel_modesetting

The W530 has a rather annoying hybrid graphic card scheme: both a intel HD integrated card and nvidia K2000M.

In the "device driver" part of kernel config, I selected both nouveau and intel drivers to be module.

and here is the xorg log file after it failed to start:

http://pastebin.com/BSfSqCQ2

I found xorg matched several drivers

[ 5156.263] (==) Matched intel as autoconfigured driver 0
[ 5156.263] (==) Matched nouveau as autoconfigured driver 1
[ 5156.263] (==) Matched nv as autoconfigured driver 2
[ 5156.263] (==) Matched intel as autoconfigured driver 3
[ 5156.263] (==) Matched modesetting as autoconfigured driver 4
[ 5156.263] (==) Matched fbdev as autoconfigured driver 5
[ 5156.263] (==) Matched vesa as autoconfigured driver 6

however somehow, only the nouveau module is loaded successfully and unfortunately

[ 5156.268] (II) [drm] nouveau interface version: 1.1.1
[ 5156.268] (EE) No devices detected.
[ 5156.268] (EE)
Fatal server error:
[ 5156.268] (EE) no screens found(EE)
[ 5156.268] (EE)

it also failed.

1. What should I do?

2. What is "nv" "intel" "modsetting" "fbdev" "vesa" modules? Where could I find them?

3. Why nouveau failed to detect devices, maybe the integrated HD graphic card conflict with nvidia card?

Thx in advance

can you post the file /etc/X11/xorg.conf and /etc/portage/make.conf?
