问题:

I Ubuntu Ubuntu laptop,installed nVidia,grub2,desktop,desktop,desktop,desktop,desktop,desktop,desktop,desktop,desktop。 我不能以任何方式改变亮度。 亮总是 100%。 我尝试了以下未工作的选项。

  • Fn + 亮向上或者亮向下按钮显示在屏幕上的icon,但brigthnes不能改变。
  • 顶部栏上的亮度 slider 不起作用。
  • grub_cmdline_linux_default="静音 splashacpi_backlight=vendor"
  • grub_cmdline_linux_default="静音 splashacpi_backlight=native"
  • grub_cmdline_linux_default="静音 splashacpi_backlight=video"
  • grub_cmdline_linux_default="静音 splashacpi_backlight=none"
  • 实用程序xbacklight显示"没有背光特性"
  • 软件更新中使用新的X.Org 显示驱动程序
  • NVIDIA二进制驱动程序版本 396
  • NVIDIA二进制驱动程序版本 390
  • 更改/sys/class/backlight/acpi_video0/上的文件 brigtness,但不工作
  • 使用最新的内核上游主线版本 v4.15.7 ( 28年2月)
  • 实时 USB Ubuntu
  • 使用/etc/X11/xorg.conf 上的文件和节"设备"。
  • 将会话作为"XOrg上的ubuntu"进行记录并禁用 Wayland

这是 journalctl -b | grep -i ( 感谢 @WinEunuuchs2Unix) )的输出

回答 1:

我创建了一个临时bash脚本来调整亮度等级。 然后,我在键盘映射设置中创建 2 sortcuts,用这里脚本向下设置 CTRL + 亮度或者 CTRL + 亮度:


#!/bin/bash



# Step brightness value


STEP=2


# Max brightness value (defult 100)


MAX=100


# Min brightness value (defult 0)


MIN=0



COMMAND=$(xrandr --verbose | grep -i brightness | cut -f2 -d':' | tr -d"[:space:]")


ACTUAL=$(bc -l < <<$COMMAND*100 | cut -f1 -d'.')



while getopts": u d" input


do


 case $input in


 u) if [ $ACTUAL -lt $MAX ];then


 TOTAL=$(bc -l < <<$(($ACTUAL+$STEP))/100)


 $(xrandr --output DP-0 --brightness $TOTAL)


 fi;;


 d) if [ $ACTUAL -gt $MIN ];then


 TOTAL=$(bc -l < <<$(($ACTUAL-$STEP))/100)


 $(xrandr --output DP-0 --brightness $TOTAL)


 fi;;


?) printf"Usage: brightness [OPTION]n"


 printf"Increase or decrease birghtness on Ubuntu Xorg.n" 


 printf"WAYLAND MUST BE DISABLEDnn"


 printf" -ut Increases brightnessn"


 printf" -dt Decreases brightnessn"


 exit 2;;


 esac


done



在设置自定义快捷键中,我添加了这里 Set Custom Shortcut


回答 2:

看起来Linux可能识别你的背光。 你在 /sys/class/backlight/acpi_video0/ 中看到 brightness 文件? 如果有,试着写一个数字,看看它是否会影响屏幕的亮度。 你可能需要这样做,如 root。

从系统的角度看,Linux甚至无法识别Fn+Brightness键,因为它们不能生成任何 scancodes,但我仍然可以通过使用 chmod 访问 brightness 文件并将整数写入到它的位置来改变显示器的亮度。


回答 3:

NVIDIA与Wayland不合作

就像其他人发现的,nVidia在Wayland方面表现不佳: Ubuntu 17.10 Wayland - ( 如何) 可以安装NVIDIA驱动程序? 。解决方案是 switch 到 Xorg。 要汇总 cl的答案,请按以下步骤操作:

  • 要安装NVIDIA驱动程序,执行 sudo apt install nvidia-384

  • 此外,你还可以强制GDM登录屏幕默认使用 Xorg。
    要实现这一点,只需执行 sudo nano/etc/gdm3/custom.conf
    删除行 # WaylandEnable=false 中的字符 #
    现在按Ctrl+X键,然后输入Y,保存更改。

  • 重新启动Ubuntu操作系统,执行 sudo reboot

你可能遇到的另一个问题是HDMI到外部监视器的声音没有声音。 要解决这里问题,请参见这里 q&: 在 NVIDIA GeForce GTX Ti 上,没有音频通过 HDMI
