CentOS6.0+下安装NVIDIA显卡驱动

linux（CentOS6.0+）下安装NVIDIA显卡驱动，disable The Nouveau kernel driver
(2013-03-31 13:49:23)
安装动因：安装本驱动程序之前，my pc 显卡风扇声音较大。最近实在忍不住了，才从师兄哪里找到了原因。原来是centos系统内核中用的是nouveau驱动程序（而my pc 的显卡是nvidia的GT 220），此驱动与nvidia完全无关。
开始安装时，按照网上的博客的说明，退出x-window界面，进入文本终端模式。运行 /# sh nvidia-driver-version.run可是出现了如下错误：
ERROR: The Nouveau kernel driver is currently in use by your system. This
driver is incompatible with the NVIDIA driver, and must be disabled
before proceeding. Please consult the NVIDIA driver README and your
Linux distribution's documentation for details on how to correctly
disable the Nouveau kernel driver.
WARNING: The modprobe configuration file to disable Nouveau,
/etc/modprobe.d/nvidia-installer-disable-nouveau.conf, is already
present. Please be sure you have rebooted your system since that file
was written. If you have rebooted, then Nouveau may be enabled for
other reasons, such as being included in the system initial ramdisk or
in your X configuration file. Please consult the NVIDIA driver README
and your Linux distribution's documentation for details on how to
correctly disable the Nouveau kernel driver.
ERROR: Installation has failed. Please see the file
'/var/log/nvidia-installer.log' for details. You may find suggestions
on fixing installation problems in the README available on the Linux.
解决的办法是：先禁用nouveau kernel driver，再安装NVIDIA驱动。
在安装之前，到nvidia官方网站下载相应的驱动程序。
我的是：NVIDIA-Linux-x86_64-310.40.run
一、关闭nouveau
1. 把nouveau kernel driver加入黑名单：
/# vi /etc/modprobe.d/blacklist.conf 在后面追加 blacklist nouveau
2. 重新建立initramfs image file：
首先备份initramfs image file
/# mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bak
其次重新建立initramfs image file
/# dracut -v /boot/initramfs-$(uname -r).img $(uname -r)
3. 重启系统至文本终端模式
/# vi /etc/inittab
最后一行“id:5:initdefault:”，将5修改成3
（5代表系统启动时默认进入x-window图形界面，3代表默认进入终端模式。我的是CentOS6.4系统）
/# reboot
4. 输入root和password，进入根用户模式下
/# lsmod | grep nouveau 确保nouveau kernel driver没有被加载
二、安装NVIDIA驱动
1. /# ./path/to/NVIDIA-Linux-x86_64-310.40.run
或
/# sh NVIDIA-Linux-x86_64-310.40.run
根据提示选择accept，yes 或 OK，即可完成安装！
2. 修改配置文件，默认进入x-window模式
/# vi /etc/inittab
最后一行id:3:initdefault: 将前面修改后的3，改回5，保存退出。
