linux 下更换显卡 ATI 还NVIDIA 或反过来

因为有事，需要将家里的ATI的独立显卡换掉，更换一个nvidia显卡，我是这么做的。
首先关机，将ATI显卡换掉，启动linux系统后系统提示xorg出错不能进入X窗口，于是
cd /etc/X11/

ls
看到 里边的三个配置文件，以及备份文件

于是 rm xorg.conf xorg.conf.livna-config-backup xorg.conf.fglrx-0
三个文件， shutdown -r now 重启后 顺利进入窗口，但是由于没驱动，画面很慢，没有任何特效。
由于安装的新显卡是nvidia的卡也就是俗称的N卡，所以



进入终端



＃yum install kmod-nvidia
载入插件: fastestmirror, refresh-packagekit

xorg-x11-drv-fglrx
这两个包有冲突，所以 yum remove 这两个包，同时yum 会提醒要删除其他的依赖包，不要管
一概删除之。

删除后
重新 yum install kmod-nvidia

安装完毕后 重启 OK le

再单位 同样道理， 只是xorg 下的配置文件可能不同 ，仔细观察 备份 后删除 OK

第一次转到google 感觉 为什么？

目的 存储学习资料，笔记 随想，
只因chinaunix 博客速度太慢
写东西多了，打开超慢。

查阅资料及其不方便。

体会，google 的快速，继续体验中。
