问题描述：linux登陆前后分辨率不一致，登陆前分辨率高，登陆后正常。两台显卡一样的机器遇到同样的问题，但解决办法不同。
解决办法：修改/etc/x11/xorg.conf文件。
1、现将机器1的xorg.conf的文件列出：
.......
Section "Monitor"
### Comment all HorizSync and VertSync values to use DDC:
Identifier "Monitor0"
ModelName "Monitor 1024x768"
### Comment all HorizSync and VertSync values to use DDC:
HorizSync 31.5 - 57.0
VertRefresh 50.0 - 70.0
Option "dpms"
EndSection
Section "Device"
Identifier "Videocard0"
Driver "i810"
EndSection
Section "Screen"
