Updating graphics card drivers on Ubuntu is often a troublesome task，In the past, you had to update in command mode after booting，Later, finally there was a graphical interface allowing you to complete it with a few clicks，But things often don't go that smoothly，This time, after updating Ubuntu to 12.10，在显示驱动更新的部分就一直出状况。
使用內建的「額外的驅動程式」更新後，一重開機不是黑屏就是顯示錯誤，最終都只能重灌再重灌，到最後便放棄更新driver。但在12.10使用一段時間後，有時會發生貼圖錯誤或畫面破碎的情形，於是只好再度面對nvidia driver更新的議題。
這次運氣不錯，Searching for foreign articles, the first one mentioned the key points，When updating the NVIDIA driver on Ubuntu 12.10，First, update linux-headers-generic to the latest version，Next, after installation，Do not restart immediately，Be sure to regenerate xorg.conf before restarting。The following are the actual steps：
After opening the terminal，Switch to root user
sudo su
Install the linux-headers-generic package
apt-get update
apt-get install linux-headers-generic
If it is already installed，Please make sure it is updated to the latest version
apt-get dist-upgrade
完成后重启
reboot
再次切换root身份
sudo su
开始安装nvidia驱动程序
apt-get install nvidia-current-updates
安装后务必执行此指令
nvidia-xconfig
重启，完成
reboot
