用安全模式进入命令行，
只要在/etc/X11/xorg.conf 中加一行就可以了
先找到
ection "Device"
Identifier "S3 Inc. 86C270-294 Savage/IX-MV"
Driver "savage"
BusID "PCI:1:0:0"
EndSection
增加
Option "BusType" "PCI"
添加后该section变成
ection "Device"
Identifier "S3 Inc. 86C270-294 Savage/IX-MV"
Driver "savage"
BusID "PCI:1:0:0"
Option "BusType" "PCI"
EndSection
重启后我就可以顺利进入X
