本人Thinkpad W520的筆記本(2.5GCpu,NV2000m顯卡),Ubuntu的顯卡驅動是官方下載的331。已在Bios里禁用集成顯卡功能。裝有Win7和Ubuntu 14.04系統,兩個系統都能正常啟動。但Ubuntu系統無法調節屏幕亮度,不管是FN+Home或是FN+End。屏幕太亮。還朢有知道解決方案的朋友能提供解決方案。

...可以一開機時調整好...或者進入獨立顯卡的控制面板裡面調整...我的也是FN沒有用...

先在终端执行以下命令,把输出贴上来:

代码: 全选

cat /etc/X11/xorg.conf

下面是您需要的信息:

先备份好/etc/X11/xorg.conf(以防改动有问题),然后编辑该文件,找到这段:

代码: 全选

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
EndSection
在EndSection前添加一行 Option "RegistryDwords" "EnableBrightnessControl=1",修改后的这一段是以下这个样子:

代码: 全选

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection
修改完成保存文件,然后重启系统再看看是否可以调节亮度了。
