求救。。屏幕刷新率一直设置不过来

[peterqq]

小弟将系统安装好了之后，。。终于把分辨率改过来了。但刷新率一直不正常。改了N多次改不过来。。系统里面显示的是85。。我想设置为1024*768 刷新率为80。请教各位大哥怎么改。我将我的xorg.conf贴出来：

# xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by failsafeDexconf, using
# values from the debconf database and some overrides to use vesa mode.
#
# You should use dexconf or another such tool for creating a "real" xorg.conf
# For example:
# sudo dpkg-reconfigure -phigh xserver-xorg

我这系统上面显示的是85.以前改了里面很多参数.怎样才能设为75

系统－－外观－－屏幕分辨率，看看那里能不能修改
