1、安装thinkfan,安装后默认自动启动
sudo apt-get install thinkfan sysfsutils
2、配置和激活thinkfan
/etc/init.d/thinkfan
更改START=no为START=yes。
3、手动更改转速
echo level 0 | sudo tee /proc/acpi/ibm/fan (fan off)
echo level 2 | sudo tee /proc/acpi/ibm/fan (low speed)
echo level 4 | sudo tee /proc/acpi/ibm/fan (medium speed)
echo level 7 | sudo tee /proc/acpi/ibm/fan (maximum speed)
echo level auto | sudo tee /proc/acpi/ibm/fan (automatic – default)
echo level disengaged | sudo tee /proc/acpi/ibm/fan (disengaged)
4、后记
笔记本是X220i,第一次在这个系列笔记本上用ubuntu,而且是11.10,安装后风扇就狂转,问题的原因是gnome 3占用很多CPU资源,虽然上述方法可以解决问题,但过一会,CPU会很热,换回gnome 2正常。
