安装更新后 thinkpad t61 显卡驱动失效！！！！！

[hukaiforever]

安装了下更新包 结果把显卡驱动给弄坏了
知道瞎折腾的后果了
代码:
sudo nvidia-xconfig

出现这样的提示：
代码:
Using X configuration file: "/etc/X11/xorg.conf".
Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup'
New X configuration file written to '/etc/X11/xorg.conf'


我再把xorg.conf的内容贴出来
代码:
Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
EndSection

Section "Module"
Load "glx"
EndSection

Section "InputDevice"
Identifier "Keyboard0"
Driver "keyboard"
EndSection

Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "auto"
Option "Device" "/dev/psaux"
Option "Emulate3Buttons" "no"
Option "ZAxisMapping" "4 5"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Device"
Identifier "Configured Video Device"
Driver "nvidia"
EndSection

Section "Screen"
Identifier "Default Screen"
Device "Configured Video Device"
Monitor "Configured Monitor"
DefaultDepth 24
Option "NoLogo" "True"
SubSection "Display"
Depth 24
Modes "nvidia-auto-select"
EndSubSection
EndSection


我想通过 系统》系统设置》硬件驱动 安装 177版本的驱动 点完以后没有反应


在线等解决方法，谢谢各位
