在i8kmon Ubuntu 14.04中设置温度阈值
我的戴尔Inspiron 15R出现了过热问题，并安装了i8kmon来控制Ubuntu 14.04上的风扇速度。
这是’lm-sensors’输出的副本：
coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +62.0°C (high = +87.0°C, crit = +105.0°C) Core 0: +57.0°C (high = +87.0°C, crit = +105.0°C) Core 1: +61.0°C (high = +87.0°C, crit = +105.0°C) i8k-virtual-0 Adapter: Virtual device Right Fan: 0 RPM CPU: +62.0°C
即使将/etc/i8kmon的温度阈值设置为：
set config(daemon) 1 # Automatic fan control, override with --auto option set config(auto) 1 # Report status on stdout, override with --verbose option set config(verbose) 1 # Status check timeout (seconds), override with --timeout option set config(timeout) 1 # Temperature thresholds: {fan_speeds low_ac high_ac low_batt high_batt} set config(0) {{0 -} -1 55 -1 55} set config(1) {{1 -} 55 70 55 70} set config(2) {{2 -} 60 128 60 128}
风扇应该启动时不启动。 什么可能是错的想法？ 以下是使用--verbose选项手动运行i8kmon时的log副本：

似乎温度是错误的， i8kmon没有打开风扇。
根据lm-sensors ：
i8k-virtual-0 Adapter: Virtual device Right Fan: 0 RPM
您有一个唯一的Right Fan ，因此左侧风扇值应始终为-1 。 您必须在文件/etc/i8kmon.conf set config更改为以下值：
set config(0) {{-1 0} -1 40 -1 40} set config(1) {{-1 1} 40 60 40 60} set config(2) {{-1 2} 60 128 60 128} set config(3) {{-1 2} 60 128 60 128}
在状态{-1 0} ，没有左风扇，右风扇关闭，在状态{-1 1} ，右风扇应该在低速运行，而在状态{-1 2}它应该全速运行。 其他值，例如40 60 40 60 ，对应于每个状态的温度阈值—最小值和最大值—有和没有交流电源。
您还需要添加以下选项：
# Run as daemon, override with --daemon option set config(daemon) 0 # Automatic fan control, override with --auto option set config(auto) 1 # Report status on stdout, override with --verbose option set config(verbose) 1 # Status check timeout (seconds), override with --timeout option set config(timeout) 20
最后，您需要在/etc/modprobe.d/中创建包含行options i8k force=1的文件i8k.conf 。
