可能是显悄启誉卡驱动没装上把。旁搜试试把显卡重置为标准显卡试试。
重启
电脑进入grub，然后键入e，再 键入e，在最后输入空格 和1，回车，按b以单启段用户启动linux。
进入命令行，可以输入system－config－display修改显卡 改成vesa.
或者进入／etc／x11下通过vi编辑器编辑xorg.conf文件。
下面是该文件。
# Xorg configuration created by system-config-display

EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection
修改driver对应的值为 vesa
Section "Device"
Identifier "Videocard0"
Driver "vesa"
EndSection
重新启动计算机
这样可以保持 800＊600的分辨率。然后在按照上篇文章的方法，安装驱动。
祝你好运！
