我们在一台带有板载显卡的 PC 上运行 Ubuntu 9.04 Jaunty。我们安装了新的显卡 NVidia ENGT430 及其驱动程序。
但是重新生成 Xorg.conf 后，X11 将无法加载，并出现以下错误。
Fatal Server Error. No Screens found.
运行 Xorg -configure 时，我们得到以下内容：
Number of created screens does not match number of detected devices.
Configuration failed.
并且输出 Xorg.conf 为：
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" RightOf "Screen0"
InputDevice "Mouse0" "CorePointer"
