好多方法试过了，例如acpi_backlight=vendor / intel 都不行

在主目录下ls有
use_bios_initial_backlight~
use_bios_initial_backlighy~
use_bios_initial_backlighz~

谢谢各位了 ！！

那么这个可以自己设定亮度值吗?

非常感谢你！！

應該可以手動調整
Panel indicator allows to set brightness level manually, whenever user choose this option then webcam won't take samples from webcam.

poloshiao,

你好，我想问下你的G410的AMD显卡怎么安装的？

G410

1. http://shop.lenovo.com/us/en/laptops/es ... #techspecs
Graphics : Intel® HD Graphics 4600

G410的AMD显卡

2. 並沒有看到 AMD 顯卡
3. 如果你確信你有 AMD 顯卡
使用 Live CD/DVD/USB 開機登入 試用桌面
把下面指令 複製 貼進終端機 執行
sudo lshw -numeric -class video
把結果直接複製 貼上來
