我的acer 4752g本子，intel集显和nvidia geforce GT 540M的双显卡，在gentoo中却搞不定显卡驱动。安装了vesa,intel,nouveau驱动，只有vesa能够工作。应该是1366X768的分辨率只能达到1024X768，字体被压成扁平，有些难看。不知该如何安装双显卡驱动和配置X？

如果用vesa驱动，没有/etc/X11/xorg.conf也行。如果用intel驱动，也不会自动生成/etc/X11/xorg.conf文件。运行Xorg -configure会生成~/xorg.conf.new文件，cp ~/xorg.conf.new /etc/X11/xorg.conf也不管用。

也就是说，你根本就没有配置过 xorg.conf 文件，那怎么让X知道你需要什么驱动呢？既然你都装了，那肯定用默认的vesa呀。

Xorg -configure 生成的配置不太靠普，还是网上找一个配置修改一下吧。

庆祝一下，现在可以在BIOS中关闭N卡的情况使用Intel驱动了，分辨率达到1366x768，原先的失败是因为配置内核时漏掉了Enable modesetting on intel by default这个选项。
Device Drivers --->
  Graphics support --->
    /dev/agpgart (AGP Support) --->
    <*>  Intel 440LX/BX/GX, I8xx and E7x05 chipset support
    Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) --->
    <*>  Intel 830M, 845G, 852GM, 855GM, 865G (i915 driver)
         i915 driver
   
  •     Enable modesetting on intel by default
    谢谢各位，这是阶段性的成果，下步又慢慢折腾N卡了。
