裝好 nVIDIA 官方驅動後,筆記本屏幕就無法調節亮度了,這當然是個 Bug。
打開 /etc/X11/xorg.conf,找到這一部分:
Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" EndSection
加上一行,變爲:
Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" Option "RegistryDwords" "EnableBrightnessControl=1" EndSection
這樣就好了。
