在 Lubuntu 16.04 上调整亮度

在 Lubuntu 16.04 上调整亮度

我喜欢调整背光。因此我尝试使用

sudo apt-get install -y xbacklight
[sudo] password for ubuntu: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
xbacklight is already the newest version (1.2.1-1build1).
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.

没有任何成功。它遵循我的显卡和驱动程序:

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation G73 [GeForce 7600 GT] [10de:0391] (rev a1)
    Kernel driver in use: nouveau
    Kernel modules: nvidiafb, nouveau

这是我当前的亮度和分辨率设置:

Gamma:      1.0:1.0:1.0
Brightness: 1.0
Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 4096 x 4096
VGA-1 disconnected (normal left inverted right x axis y axis)
LVDS-1 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 470mm x 300mm

答案1

我卸载了背光并使用命令:

sudo bash -c "echo 1 > /sys/class/backlight/apple_backlight/brightness;

将 baklight 设置为“1”。我可以使用 1 到 15 范围内的整数。
