一个关于液晶显示器的问题，希望有经验的哥们帮忙看看

单位新换的电脑，17的液晶显示器，2006.0的profile，Xorg是7.0的，xorgconfig配置的X，但是进入图形界面后，显示器提示，“超出范围”，看KDE下的显示设置，显示刷新率为85，显然高出了液晶显示器的标准75Hz。从无问题的SLED下复制xorg.conf过来问题依旧。
哪位知道在xorg.conf中怎样手动设置刷新率？
似乎有一个在X下的工具，可以调整好显示器，然后把它的输出，复制到xorg.conf的ModeLine （or Mode）参数，但是好就不用这个工具了，我给忘了。。。。。。

1. 把 xorg.conf 中 monitor 段的 HorizSync VertRefresh ModeLine 都禁用。
只在 Screen 段中指定分辨率。
startx
看 /var/log/Xorg.0.log, 现代的驱动都可以从显示器读取信息的。
所有支持的 modeline 都能看见。

2. 启动 X 后在一终端中用 xdivtune 调节，只能调节 VGA 接口的，主要用于调节屏幕偏移，刷新率也能调，单击 show，命令行中显示 modeline 。

注意 DVI 接口的显示器不能用。

的确需要自己定义一个合适的 modeline.

看看这个工具对你适用吗？

看看说明书你显示器的水平和垂直刷新率是多少,然后手动写在xorg.conf里

在使用xorgconfig配置时，是按照说明书配置的。但是进入KDM后，还是85Hz

按理说LCD 85Hz直接黑屏，根本亮不了

modeline直接用gtf生成，系统自带，而且最好自己设一下，否则xorg好像倾向于使用最高的那个

只要有 ddc 和 i2c （应该是默认启动的）就肯定能自动探测，而且结果是最好的，


看下面，绿的是所有的支持的 modeline ，蓝的是选择的 modeline，确实是我的显示器的最大能力。
我的 xorg.conf 里只指定了分辨率，显示器的所有参数都是 dcc 读出的。
