我最近在Mac Book Pro 7,1上安装了Ubuntu 11.10。我安装了NVIDIA驱动程序(285)。亮度键正常工作(F1和F2),我看到显示亮度的框,但它什么也没做。我可以在“ NVIDIA X服务器设置”应用程序中更改亮度。在不卸载驱动程序的情况下如何获得亮度?提前致谢。

Answers:
我可以在Ubuntu 12.04上的Lenovo W530上使用亮度键。
如今,X会自动进行自我配置,因此创建xorg.conf文件可能会使您的系统不灵活。相反,您可以在/usr/share/X11/xorg.conf.d/中的文件中添加一个节,并且X将在自动生成的配置中包括该节。
因此,要使屏幕亮度键与Nvidia图形卡一起使用,请在xorg.conf.d目录中创建一个文件,例如:
sudo gedit /usr/share/X11/xorg.conf.d/10-nvidia-brightness.conf
将以下内容粘贴到文件中:
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "Quadro K1000M"
Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection
注销并重新登录,或重新启动,您的亮度键现在应该可以工作了!
(我在这里写了)
我的笔记本电脑有类似的问题,您需要添加一个选项 /etc/X11/xorg.conf
运行命令:
sudo nano /etc/X11/xorg.conf
找到“设备”部分,并添加以下内容
Option "RegistryDwords" "EnableBrightnessControl=1"
您需要启用亮度控制。打开终端并键入sudo gedit /etc/x11/xorg.conf
,然后Option "RegistryDwords" "EnableBrightnessControl=1"
在device部分中添加,将其粘贴到新行中。然后重新启动计算机,一切都会正常。
感谢您提供出色的脚本qgj。令人遗憾的是,该错误仍然存在,并且需要解决方法。由于James的选项对于我的特定显示类型在nvidia设置中不再有效,因此我遇到了与James出错相同的问题。幸运的是,背光亮度有一个更好的设置。我已经修改了bash脚本以改为使用此设置。
#!/bin/bash
# This script was originally created by 'qgj' from askubuntu. It has been modified
# to work using the BacklightBrighness setting available for some displays on the currrent nvidia driver
# It has also been modified to remove display specific configuration, instead applying the setting to all
# active displays which support the BacklightBrightness setting.
# Tested only with nvidia-settings-319.12 and nvidia-drivers-331.20 on Linux Mint 17 Mate
#
# Requirements:
# - NVIDIA Drivers (e.g. nvidia-current in Ubuntu)
# - NVIDIA Settings (nvidia-settings in Ubuntu)
#
# This script can be used to change the brightness on systems with an NVIDIA graphics card
# that lack the support for changing the brightness (probably needing acpi backlight).
# It uses "nvidia-settings -a" to assign new gamma or brightness values to the display.
#
# If this script fails, your display likely does not support the 'BacklightBrightness' option.
# In that event, execute 'nvidia-settings -n -q all' to see which options are available for the displays
#
# "nvidia-brightness.sh" may be run from the command line or can be assigned to the brightness keys on your Keyboard
# Type "nvidia-brightness.sh --help" for valid options.

您的里程可能因该脚本而异,因为某些显示器/适配器支持不同的选项。如果遇到问题,请阅读脚本中的帮助和注释。
希望它能对某人有所帮助!
有些计算机(例如我的联想W520)不Option "RegistryDwords" "EnableBrightnessControl=1"
符合要求。如果您是那些不幸的人之一,则可以尝试nvidiabl
驱动程序(在此处链接)。
该nvidiabl
驱动器提供改变屏幕亮度之有道。在某些笔记本电脑上,Option "RegistryDwords" "EnableBrightnessControl=1"
骇客会导致背光控制器或您的GPU发出高音调噪音。
只需从此处下载并安装最新的Deb文件:https : //github.com/downloads/guillaumezin/nvidiabl/nvidiabl-dkms_0.72_all.deb
并运行:
echo "nvidiabl" | sudo tee -a /etc/modules
以确保在计算机引导时加载模块。
我个人使用Vaio VPCCW21FX(Nvidia Graphic)和Ubuntu Studio 11.10 ..我尝试了许多解决方案,但没有任何方法可以解决LCD亮度问题!最后编写了这两个perl文件,以在Nvidia驱动程序配置文件中手动设置亮度/对比度和Gamma函数。
仅当您能够在Nvidia X服务器设置中更改亮度时,此功能才有用
步骤1:创建此文件并将其命名为“ Brightness-Up.pl”(您可以使用任何文本编辑工具,例如:gedit,nano,vi等。复制并粘贴)
### Code by forgottenrip@yahoo.com ###
my $find1 = "0/RedBrightness=";my $find2 = "0/RedGamma=";
open FILE, "<Nvidia-Settings.cfg";
my @lines = <FILE>;
for (@lines) {
if ($_ =~ /$find1/) { chomp $_;$value= substr($_,16,5); }
if ($_ =~ /$find2/) { chomp $_;$value2= substr($_,11,5);}
}
my @Lines;
if ( $value > 0.0) { $value = $value - 0.30 };
if ( $value2 > 1.1) { $value2 = $value2 - 0.08 };
$last_value = $value + 0.30;
$Lines[0] ="0/RedBrightness=".$last_value;
$Lines[1] ="0/GreenBrightness=".$last_value;;
$Lines[2] ="0/BlueBrightness=".$last_value;;
$last_value = $value + 0.30;
$Lines[3] ="0/RedContrast=".$last_value;;
$Lines[4] ="0/GreenContrast=".$last_value;;
$Lines[5] ="0/BlueContrast=".$last_value;;
$last_value = $value2 + 0.08;
$Lines[6] ="0/RedGamma=".$last_value;;
$Lines[7] ="0/GreenGamma=".$last_value;;
$Lines[8] ="0/BlueGamma=".$last_value;;
$filename = "Nvidia-Settings.cfg";
open fh2,'>',$filename or die ("can't open '$filename': $! \n");
foreach ( @Lines )
{ chomp;print "$_\n";print fh2 "$_\n"; };
close fh2;
`nvidia-settings -l --config=Nvidia-Settings.cfg`;
步骤2:然后制作另一个文件,将其命名为“ Brightness-Down.pl”,并填充以下代码:
### Code by forgottenrip@yahoo.com ###
my $find1 = "0/RedBrightness=";my $find2 = "0/RedGamma=";
open FILE, "<Nvidia-Settings.cfg";
my @lines = <FILE>;
for (@lines) {
if ($_ =~ /$find1/) {chomp $_;$value= substr($_,16,5);}
if ($_ =~ /$find2/) {chomp $_;$value2= substr($_,11,5);}
}
my @Lines;
if ( $value < -0.80) { $value = $value + 0.30 };
if ( $value2 < 0.8) { $value2 = $value2 + 0.08 };
$last_value = $value - 0.30;
$Lines[0] ="0/RedBrightness=".$last_value;
$Lines[1] ="0/GreenBrightness=".$last_value;;
$Lines[2] ="0/BlueBrightness=".$last_value;;
$last_value = $value - 0.30;
$Lines[3] ="0/RedContrast=".$last_value;;
$Lines[4] ="0/GreenContrast=".$last_value;;
$Lines[5] ="0/BlueContrast=".$last_value;;
$last_value = $value2 - 0.08;
$Lines[6] ="0/RedGamma=".$last_value;;
$Lines[7] ="0/GreenGamma=".$last_value;;
$Lines[8] ="0/BlueGamma=".$last_value;;
$filename = "Nvidia-Settings.cfg";
open fh2,'>',$filename or die ("can't open '$filename': $! \n");
foreach ( @Lines )
{ chomp;print "$_\n";print fh2 "$_\n"; };
close fh2;
`nvidia-settings -l --config=Nvidia-Settings.cfg`;
步骤3:您需要创建另一个包含Nvidia设置的文件。将其命名为“ Nvidia-Settings.cfg”,其名称的写法必须完全相同。填充:
0/RedBrightness=0.1
0/GreenBrightness=0.1
0/BlueBrightness=0.1
0/RedContrast=0.1
0/GreenContrast=0.1
0/BlueContrast=0.1
0/RedGamma=1.14
0/GreenGamma=1.14
0/BlueGamma=1.14
而已!现在将这些文件放在唯一的文件夹中。.您必须将功能键绑定到这两个perl 文件。您可以使用Compiz>命令来完成。运行以下命令以安装compizconfig-settings-manager
sudo apt-get install compizconfig-settings-manager
或者甚至可以在shell(终端)中使用以下两个命令单独运行:
user$ perl Brightness/Brightness-Up.pl
user$ perl Brightness/Brightness-Down.pl
我将亮度文件放在其中的文件夹中。
NVIDIA亮度bash脚本
上面的perl脚本对我不起作用,所以我写了自己的脚本作为bash脚本(因为我不知道perl)。它有点长,但是它是自己创建设置文件的,可以与命令行选项一起使用,以同时调整亮度或灰度系数。我将它与--brightness-up和--brightness-down开关一起用于键盘上的亮度键。易于在XFCE4中进行分配,当然也可以在KDE / GNOME中进行分配。

其他答案是尝试的好步骤,但是请注意,Ubuntu / Linux内核和Nvidia驱动程序的某些组合将无法使用。我使用12.04已有多年,即使我尝试了上述所有答案,我也无法获得任何Nvidia驱动程序来支持Macbook Pro 5,5上的屏幕变暗。
当我最终升级到14.04时,我尝试了Nouveau驱动程序,该驱动程序支持屏幕调光,并且速度通常更快,更可靠。不幸的是,它不支持挂起/恢复,因此在笔记本电脑上无法使用。我切换回Nvidia,但是几个驱动程序导致X / lightdm崩溃,甚至无法登录。我最终发现Nvidia 340驱动程序在Macbook Pro 5,5和Ubuntu 14.04上稳定并且还支持调光。
我正在使用NVIDIA图形卡,但遇到了像您这样的问题。
但是我尝试了一下,并且可以正常工作:
1.使用以下命令安装NVIDIA驱动程序:
sudo apt-add-repository ppa:ubuntu-x-swat / x-updates
sudo apt-get update
sudo apt-get install nvidia-current
2.然后,重新启动
3.完成。
来源:http : //noob-tech.blogspot.co.id/2015/04/Install-VGA-Driver-On-Ubuntu.html
从16.04升级后,我在Ubuntu 16.10中遇到了同样的问题。在xorg.conf文件(/ usr / share / doc / xserver-xorg-video-intel /)中,我将驱动程序从“ intel”更改为“ nvidia”。
回到linux内核4.4,我的Macbook Pro 2013 Late 15上解决了该问题。
