备份好/etc/X11/XF86Config-4，然后改XF86Config-4相应的部份。看一下情况何如？？？

把上面这段改成如下。。

Section "Device"
Identifier "Cirrus Logic GD544x"
SERVER SVGA
Driver "cirrus"
BoardName "Unknown"
EndSection
并把下面这段删除，试一下。

Section "Device"
Identifier "Linux Frame Buffer"
Driver "fbdev"
BoardName "Unknown"
EndSection


不要忘记备份好文件。
