我在Windows里面可以1600X1200 60Hz，可是我在Ubuntu里面设置不了了，驱动也装了，我的是8500GT的显卡，显示器是PHILIPS 107Q6，我想改成1024X768 85HZ ，下面是我的/etc/X11/xorg.conf，没有传说中的那几行：

Section "Monitor"


HorizSync 30-83

VertRefresh 56-76
和
SubSection "Display"

Depth 1

Modes "1024x768" "800x600" "640x480"

EndSubSection

看不出修改哪里：

还有，发现有个文件/etc/usplash.conf 不知道干嘛的：
# Usplash configuration file
# These parameters will only apply after running update-initramfs.

你先安装个 nvidia-xconfig

命令 ：sudo apt-get install nvidia-xconfig

安装好了以后就可以显示你的显卡了 N卡的很好调整 你GOOGLE会有很多设置方法

或者就是在工具里选中显卡与显示器的项目 详细调整 但是你要知道你的显卡和显示器的详细参数

如果你的应用程序里没有 显卡与显示器 的 你到 系统-首选项-主菜单 里添加就可以了

你其他的不需要改的 尤其注意的是 UB的刷新率好像有点和XP下不一样 我60的刷新率 在UB下才显示50 你自己注意显卡驱动是否激活就好了 不激活就没有作用 就算你的分辨率调整好了也没有用的
