ubuntu14.04中的一些问题(持续更新)

一、调节屏幕亮度（资料来源：http://itsfoss.com/fix-brightness-ubuntu-1310/）

下面英文的意思大致就是在/usr/share/X11/xorg.conf.d/   创建一个文档 20-intel.conf，并写入下面提示的代码

Open a terminal and create the following configuration file, if it does not exist:

$ sudo touch /usr/share/X11/xorg.conf.d/20-intel.conf

Now we need to edit this file. You can use any editor be it a terminal one or graphical.

$ sudo gedit /usr/share/X11/xorg.conf.d/20-intel.conf

Add the following lines to this file:

Section "Device"
        Identifier  "card0"
        Driver      "intel"
        Option      "Backlight"  "intel_backlight"
        BusID       "PCI:0:2:0"

EndSection

Save it. Log out and log in back. The brightness control should be working through function keys now:
