我的刷新率只显示：0HZ，我现在还郁闷呢！每当我的分辨率从默认的1280*1024调成1024*768时就会导致颜色质量出问题。
之前只是想更新一下ati的显卡驱动，但找了老半天没找着ubuntu9.04的驱动，我的显卡是hd2600的～在安装显卡出错后，我再xie载，重启后就出上述问题了～
然后再想办法整回原状，参考了网上的方法改了x11下的xorg.conf：
代码： 全选
# xorg.conf (X.Org 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 xorg.conf manual page.
# (Type "man 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.
#
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
#
# 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
