黑呵曰：你不得不感歎Linux的強大。如果windows因為顯卡驅動開不了機你會怎麼辦？重裝。。。。Linux提供了一個強大的命令行（windows的那個簡直稱不上命令行）讓你直接修改設置，修改完成不用重啟，就能運行。Linux的確比windows好。
進入命令行用vi命令修改以下文件
/etc/X11/Xorg.conf或者可能是/etc/X11/XF86config.conf
修改Xorg.conf是件簡單的事，配置文件結構簡單，也沒有復雜的語法，但是一但配置失敗，後果是比較嚴重的，，所以強烈建議每次修改之前做好備份工作。
Xorg.conf一般位於/etc/X11/xorg.conf
包含了你的顯卡信息和顯示器信息。

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg
