我在 Gentoo 上设置 X.org 时遇到问题。
目前我已经安装了内核 2.6.37-gentoo-r4 并针对该内核构建了 X。我安装了 nouveau 驱动程序，从我在终端中看到的情况来看，它们似乎工作正常。我有 nVIdia GeForce 9500M GS，驱动程序应该支持它，因为它使用 NV84 (G84) 核心。
当我尝试启动x时，我得到的是：

那么我错过了什么？
答案1
No DRICreatePCIBusID symbol当我尝试X -configure在我的系统上运行时，我也会收到错误。值得庆幸的是，我实际上并不需要运行它才能让 X 运行。这些是我的里面的文件/etc/X11/xorg.conf.d/：
- 10-evdev.conf
- 10-monitor.conf
- 10-怪癖.conf
- 20-nouveau.conf
10-evdev.conf并10-quirks.conf随xorg-server包裹一起来。
10-monitor.conf包含来自 ArchWiki 的配置Xorg 页面，没有该Device部分，并且20-nouveau.conf来自新风格页面。
10-monitor.conf：
Section "Monitor"
Identifier "VGA-1"
Option "PreferredMode" "1280x1024"
EndSection
Section "Monitor"
Identifier "TV-1"
EndSection
Section "Screen"
Identifier "Screen0"
Device "NVIDIA Card"
DefaultDepth 24
SubSection "Display"
Depth 24
EndSubSection
EndSection
20-nouveau.conf：
Section "Device"
Identifier "NVIDIA Card"
Driver "nouveau"
EndSection
以下错误告诉我们您还没有安装 xterm 和 twm。
/etc/X11/xinit/xinitrc: line 61: xterm: command not found
/etc/X11/xinit/xinitrc: line 63: exec: xterm: not found
/etc/X11/xinit/xinitrc: line 59: twm: command not found
您可能需要emerge它们或创建一个~/.xinitrc文件来覆盖系统范围的 xinitrc 文件。
您可能想要发布尝试正常运行 X（即 startx）时的日志。您发布的日志是尝试运行后的日志Xorg -configure。
