問題描述：linux登陸前後分辨率不一致，登陸前分辨率高，登陸後正常。兩台顯卡一樣的機器遇到同樣的問題，但解決辦法不同。
解決辦法：修改/etc/x11/xorg.conf文件。
1、現將機器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"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
