本本是ThinkPad T410i,安装了ubuntu 10.10之后,发现调节屏幕亮度的功能没了,每次调节亮度之后要重启才能够生效,而且下次重启之后,就又失效了。
强大的google帮助了我,我帖一下我的解决方法。
在终端一下输入下面命令,修改xorg.conf
sudo vim /etc/X11/xorg.conf
原来的内容如下:
Section "Screen"
Identifier "Default Screen"
DefaultDepth 24
EndSection
Section "Module"
Load "glx"
EndSection
Section "Device"
Identifier "Default Device"
Driver "nvidia"
Option "NoLogo" "True"
Identifier "Default Screen"
DefaultDepth 24
EndSection
Section "Module"
Load "glx"
EndSection
Section "Device"
Identifier "Default Device"
Driver "nvidia"
Option "NoLogo" "True"
EndSection
在Section "Device"里面加多一行
Option "RegistryDwords" "EnableBrightnessControl=1",
修改后如下
Section "Screen"
Identifier "Default Screen"
DefaultDepth 24
EndSection
Section "Module"
Load "glx"
EndSection
Section "Device"
Identifier "Default Device"
Driver "nvidia"
Option "NoLogo" "True"
Option "RegistryDwords" "EnableBrightnessControl=1"
Identifier "Default Screen"
DefaultDepth 24
EndSection
Section "Module"
Load "glx"
EndSection
Section "Device"
Identifier "Default Device"
Driver "nvidia"
Option "NoLogo" "True"
Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection
然后保存,重启之后你就会发现,可以在ubuntu下面调节屏幕亮度了!
