[问题]登录界面 频率超出限制

[byygxs002]

我装的ubuntu8.04，显卡是ATI 下1650*2，开了受限驱动

进入登录画面的时候显示“频率超出限制”，可以看到画面，只是字体显示有点模糊，
登录之后调节分辨率为1280*1024，刷新率为60Hz，一切正常，也没显示“频率超出限制“
但是当把分辨率调到1600*1200时，就会显示“频率超出限制”，跟登录画面的问题有点像
当把刷新率调到43Hz时（分辨率是1280*1024），也会显示“频率超出限制”，只是此时画面更模糊


虽然这样还是可以进入系统，进入后也一切正常，只是登录窗口那样不爽
求高人指点

我的xorg.conf文件如下：
