昨天在受限驱动里装好7600GS以后进登录界面就黑屏，我的benq PF71G+显示器显示“Out of range”，盲打进用户名密码可以听到启动声音，看样子就是刷新率的问题，暂时在LiveCD中把备份的xorg.conf恢复回去，启动正常了。
今天继续解决这个问题，详细研究了xconfig以后生成的xorg.conf文件， 把HorizSync和VertRefresh数值调低 ，把monitor和Device的ModelName手动填上，我的是BenQ FP71G+和nVidia Corporation G70 [GeForce 7600 GS]，Google一下找到一个Screen的配置文件，先不管了全部copy过来，重启，OK了。
附xorg.conf文件完整配置，如果有人跟我同样的状况可以完全copy后把ModelName改成自己的应该就可以了。
