Linux安装Nvidia显卡驱动：禁用The Nouveau kernel driver的方法！

系统：Red Hat Enterprise 6（32位）

显卡：Nvidia Gforce 7300GT

将驱动从Nvidia官网下载回来后 进入文本模式直接运行安装,发现提示以下错误:

错误日志以下：

上面是安装显卡驱动的时候的错误提示：意思就是：

Nouveau kernel driver 这个驱动正在被系统使用,这个驱动和Nvidia驱动冲突,要想继续安装,则必须禁用此驱动！由于RHEL 6 系统默认装的显卡驱动就是Nouveau .　Nouveau是一个由爱好者组织的针对NVIDIA显卡开发第三方开源3D驱动的共同项目，而且Nouveau是在彻底没有获得NVIDIA任何支 持的状况下进行开发的，Nouveau算是X.Org基金会的一个项目.

解决办法以下：

也即关闭Nouveau：

1)把驱动加入黑名单中: /etc/modprobe.d/blacklist.conf  在后面加入：
blacklist nouveau
2) 使用 dracut从新创建  initramfs p_w_picpath file :
* 备份 the initramfs file
$ sudo mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bak
* 从新创建 the initramfs file
$ sudo dracut -v /boot/initramfs-$(uname -r).img $(uname -r)
3) 重启系统至文本模式,init 3 这个能够修改/etc/inittab 文件 init 3是文本模式,

   init 5是图形界面模式.重启以后,进入文本模式，其实能够发现字体变大了,也就是说驱动没有被加载,成功禁用了Nouveau

4)检查nouveau driver确保没有被加载！
$ lsmod | grep nouveau
5) 运行安装文件
$ sudo ./NVIDIA-Linux-x86_64-195.36.15-pkg2.run

sh NVIDIA-Linux-x86-275.09.07.run
安装过程当中根据相应提示,便可完成安装.
6)重启系统,进入图形界面,便可发现出现了以下选项：

没安装以前提示就是 须要硬件3D支持！

系统-->首选项-->NVIDIA X Server Settings

至此已完成LInux下显卡驱动的安装！

Good Luck，Enjoy it ！
