如果你用的是Redhat的话你的X window配置文件是
/etc/X11/XF86Config
Slackware的X Window配置文件是
/etc/XF86Config

在那个文件中你会看到象下面这样的东西：

# 640x400 @ 70 Hz, 31.5 kHz hsync
Modeline "640x400" 25.175 640 664 760 800 400 409 411 450
# 640x480 @ 60 Hz, 31.5 kHz hsync
Modeline "640x480" 25.175 640 664 760 800 480 491 493 525
# 800x600 @ 56 Hz, 35.15 kHz hsync
ModeLine "800x600" 36 800 824 896 1024 600 601 603 625
# 1024x768 @ 87 Hz interlaced, 35.5 kHz hsync
Modeline "1024x768" 44.9 1024 1048 1208 1264 768 776 784 817

Modeline "1024x768" 75 1024 1048 1184 1328 768 771 777 806

Modeline "1280x1024" 80 1280 1296 1512 1568 1024 1025 1037 1165
Interlace

# 1024x768 @ 76 Hz, 62.5 kHz hsync
Modeline "1024x768" 85 1024 1032 1152 1360 768 784 787 823
# 1280x1024 @ 61 Hz, 64.2 kHz hsync
Modeline "1280x1024" 110 1280 1328 1512 1712 1024 1025 1028 1054

# 1280x1024 @ 74 Hz, 78.85 kHz hsync
Modeline "1280x1024" 135 1280 1312 1456 1712 1024 1027 1030 1064

# 1280x1024 @ 76 Hz, 81.13 kHz hsync
Modeline "1280x1024" 135 1280 1312 1416 1664 1024 1027 1030 1064

这些东西控制这你的显示卡的设置，例如
下面这一行注释说分辨率为1280x1024，刷新速率为76赫兹，行扫频率为81.13千赫兹
# 1280x1024 @ 76 Hz, 81.13 kHz hsync
下面这一行具体设置显示卡：
Modeline "1280x1024" 135 1280 1312 1416 1664 1024 1027 1030 1064


这行中每个项目的意义如下：（从左到右）

模式行，分辨率，像元频率（兆赫兹），每行像元数，行同步（消隐）脉冲开始的时钟周期，行同步（消隐）脉冲结束的时钟周期，每行的时钟周期数，每帧的图象行数，帧同步脉冲开始的扫描行数，帧同步脉冲结束的扫描行数，每帧的扫描行数。

调整这些数目你可以最大限度地使用你的显示卡和显示器，例如您的显示卡有一兆存储器，您
可以设置成1152x900的分辨率。:-)需要当心的是仔细核对你的显示器所允许的扫描频率，有
些显示器当收到过高的扫描同步脉冲后会烧毁行扫描晶体管。我就烧过一个显示器，那晶体管
还不太好买，彩电的行扫描晶体管通常不能用，频率太低，功率也不够大，上去就烧。:-(

下一个问题是你的显示卡有什么像元频率可以用，例如上面的行要求135MHz，但你的卡只有
125兆赫兹，怎么办呢？也好办，用emacs或vi把135改为125就完了。

如果你的配置文件中对应于您所要的分辨率有多个模式行的话，您可以将其它频率较低的模式
行用#号给封上，只留下你想要的频率就能改变扫描频率了。

祝你成功！

烧显示器我可不能负责！　:-)

Does PnP mean "Plug and Pray"?

还可以用XF86带的xvidtune软件调整

感觉不是那么爽，这样的修改好象是个虚拟的，怎么看怎么象是800*600的，而不是1024*768，就算这样改了，下次重起电脑还是原来的分辨率~~~~~~~~~ :174: :174: :174: :174: :174: :044: :256: :0318: :754: :110: :167: :037: :249: :0312: :757: :103:
