双显 我发现只要有xorg.conf存在 就黑屏和花屏

[zyzhang12]

intel和NVIDIA GT 540的双显 安装完 nvidia-current后进入etc/x11下 并没有Xorg.conf这个文件

如果安装Nvidia-linux-295.20.run 配置X后启动就会 无法进入 只能停留在控制台 查看X 启动错误和日志 显示没检测到设备（屏幕 或显卡）

恢复模式下 删除Xorg.conf 再启动 屏幕正常

一下是安装NVidia 各种驱动后留下的Xorg.cong：

那是文件配置有问题吧
我的没这个文件还达不到最佳分辨率呢，必须手动写这个文件才有1366x768的分辨率
