在网上查了,无法调节亮度是没有安装驱动,那怎么安装驱动?
nvidia官网下载好了的NVIDIA-Linux-x86_64-340.58.run,
我使用
  1. sudo sh NVIDIA-Linux-x86_64-340.58.run
Copy the Code
命令运行,但是结果如下:
  1. ➜  ~  cat /var/log/nvidia-installer.log
  2. nvidia-installer log file '/var/log/nvidia-installer.log'
  3. creation time: Sun Jan  4 22:07:39 2015
  4. installer version: 340.65
  5. PATH: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
  6. nvidia-installer command line:
  7.     ./nvidia-installer
  8. Using: nvidia-installer ncurses user interface
  9. -> The file '/tmp/.X0-lock' exists and appears to contain the process ID '7830' of a runnning X server.
  10. ERROR: You appear to be running an X server; please exit X before installing.  For further details, please see the section INSTALLING THE NVIDIA DRIVER in the README available on the Linux driver download page at www.nvidia.com.

笔记本调节亮度:
sudo  su
echo 400 > /sys/class/backlight/intel_xxx/brightness    我这里全亮是976    数字可以自己调节。

笔记本不推荐冒然安装Nvidia驱动
我安装的是 bumblebee ,这个会自动关闭独显。需要的时候请运行 optirun xxx

我使用gedit 编辑brightness后无法保存,提示如下:
gedit 无法在保存新文件时备份原来的文件。您可以忽略此警告继续保存操作,但如果在保存过程中发生了错误,您可能会丢失原文件的副本。仍然要保存吗?
  1. (gedit:2855): Gtk-WARNING **: Calling Inhibit failed: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files
