求助：如何将屏幕分辨率降低？（已解决）

[changll002]

搜索过很多，也试了多遍了。也没有办法将1280x1024@75更改为1024x768@85，我的显卡为ATI9550，驱动为Xorg，显示器为SONY E200。用系统－－－首选项－－－屏幕分辨率，提示Xserver不支持XRandR扩展。无法在运行时刻对分辨率进行更改。试过在终端运行gtf 1024 768 85 然后更改/etc/X11/XF86Config-4文件也没有成功，重启后还是1280x1024@75。
先谢谢了。

麻烦你贴出你的/etc/X11/xorg.conf文件！

谢谢firehare，你回复得这么快，我却反应得这么慢，真不好意思。是这样的，我昨天改来改去结果倒改成进不了XWINDOW了，今天中午只好卸了重装了。重装后，在没有装Xorg驱动之前，用系统－－－首选项－－－屏幕分辨率，可以把分辨率改为1024x768@85的。但是装了Xorg驱动，重启进入XWINDOW，结果又是1280x1024@75。用系统－－－首选项－－－屏幕分辨率，又提示Xserver不支持XRandR扩展。无法在运行时刻对分辨率进行更改了。我不会发附件，就把/etc/X11/xorg.conf文件贴出来，麻烦你有空给看看。谢谢

我把/etc/X11/xorg.conf中的所有"1280x1024" "1280x960" "1152x864"都删除了，结果就行了。真不好意思，占用了论坛这么多地方。
