i8kmon未在Ubuntu18.04上正常工作

Question

问题

我开始注意到电脑的风扇没有必要地全速打开，所以我安装了i8kmon服务来控制它们。在我手动禁用bios风扇控制之前，i8kmon似乎无法使用i8kfan命令来控制风扇。

我的设置

• 戴尔XPS 139380
• Ubuntu 18.04

日志

服务正在运行：

服务检测到高温，但忽略了该命令：

配置文件/etc/i8kmon.conf

# Sample i8kmon configuration file (/etc/i8kmon.conf, ~/.i8kmon).
set config(use_conf)    1

set config(auto)       1

# External program to control the fans
set config(i8kfan)      /usr/bin/i8kfan

# Report status on stdout, override with --verbose option
set config(verbose)     1

# Status check timeout (seconds), override with --timeout option
set config(timeout)     2

# Temperature threshold at which the temperature is displayed in red
set config(t_high)      80

# Temperature thresholds: {fan_speeds low_ac high_ac low_batt high_batt}
# These were tested on the I8000. If you have a different Dell laptop model
# you should check the BIOS temperature monitoring and set the appropriate
# thresholds here. In doubt start with low values and gradually rise them
# until the fans are not always on when the cpu is idle.
set config(0) {{0 0}  -1  60  -1  65}
set config(1) {{1 1}  50  70  55  75}
set config(2) {{2 2}  60  80  65  85}
set config(3) {{2 2}  70 128  75 128}

# Speed values are set here to avoid i8kmon probe them at every time it starts.
set status(leftspeed)   "0 1000 2000 3000"
set status(rightspeed)  "0 1000 2000 3000"

解决方案

用/etc/init.d/i8kmon重新启动服务不会有任何改变。我发现BIOS也试图控制风扇，所以我通过snap安装了https://github.com/TomFreudenberg/dell-bios-fan-control，执行/snap/dell-bios-fan-control/2/dell-bios-fan-control 0使事情正常工作。

我认为这个设置是永久保存在bios中的，但似乎每次启动计算机时我都需要运行它。我应该把它作为一种服务添加吗？

在Ubuntu22.04和戴尔精密5520上，control的snap版本对我来说是崩溃的。

# dell-bios-fan-control 0
ioperm:: Operation not permitted
ioperm:: Operation not permitted
Segmentation fault (core dumped)

我已经编译了它的来源- https://github.com/TomFreudenberg/dell-bios-fan-control -它终于停止了球迷！
