ubuntu9.10安装成功后,默认会打开声卡的省电功能,而这种省电功能给我的Lenovo 10笔记本带来了烦人的噪声。
When ubuntu9.10 was installed successfully, audio power saving mode will be enabled by default, but this function brings boring pop noise to my Lenovo 410 Laptop.
下面的命令用来,关闭声卡的自动省电功能:
Following command can be used for disabling the audio power saving mode:
echo 0 > /sys/module/snd_hda_intel/parameters/power_save |
注意: 请注意shell的格式, > 符号两边的空格需要保留。
Notice: Please pay attention to the shell command, spaces around ‘>’ should be kept.
为了让上面的脚本在每次开机的时候运行,我们需要把它添加到/etc/rc.local,这个操作需要root权限。
In order to run the script at start up, we need to add this script to /etc/rc.local. You need to be root to modify this file.
