一般来说，在安装操作系统之后，系统会推荐一定的驱动更新，如果有些不合适，那么你可以选择手动更新。例如有的wireless无线驱动工作不正常，sudo ifconfig也不存在wlan0，那么你就必须采取手动安装方法。
首先，先判断什么驱动工作不正常。是声卡，还是显卡，还是无线模块。
然后，在去官方网站下载驱动包，注意选择操作系统和应用平台（i386，X86，X86_64），
再根据安装包的不同采取操作。是需要编译的源代码，还是bin程序。
如果是源代码，一定要先阅读readme，执行
sudo make
sudo make install
sudo reboot
例如安装realtek的无线驱动

注意：有的linux操作系统默认没有安装gcc，如Fedora 14，需要先配置gcc
su root
yum -i gcc
如果是bin安装包，则如下操作：
例如：安装ati-driver
baidu@:~/Downloads$ sudo chmod +x ati-driver-installer-11-5-x86.x86_64.run
baidu@:~/Downloads$ sudo ./ati-driver-installer-11-5-x86.x86_64.run
在按照提示操作即可。
