IBM T20 S3显卡配置

近日在IBM T20上安装Redhat Enterprise AS 4,结果虽然显卡S3 Savage/IX可以认到，但是分辨率却只能到800X600,找了半天，没搞懂到底是Xorg无法认到显卡，还是配置出错，后来发信给Alex Deucher,结果证实其实只是xorg.conf配置有问题:

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Unknown monitor"
HorizSync 31.5 - 37.9
VertRefresh 50.0 - 70.0
Option "dpms"
EndSection

修改为：

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "LCD Panel 1024x768"
HorizSync 31.5 - 48.5
VertRefresh 40.0 - 70.0
Option "dpms"
EndSection

并且添加:

Section "Device"

Option "CRT2HSync" "30-96"
Option "CRT2VRefresh" "50-160"
EndSection
