我有一台运行 Ubuntu 22.04 的 Dell Latitude 7480，我尝试安装fancontrol，但i8kutils由于我的风扇根本不工作，但运行后pwmconfig我收到以下消息：
Found the following devices:
hwmon0 is AC
hwmon1 is acpitz
hwmon2 is BAT0
hwmon3 is nvme
hwmon4 is coretemp
hwmon5 is dell_smm
hwmon6 is pch_skylake
hwmon7 is iwlwifi_1
Found the following PWM controls:
hwmon5/pwm1 current value: 0
Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon5/fan1_input current speed: 0 ... skipping!
There are no working fan sensors, all readings are 0.
Make sure you have a 3-wire fan connected.
You may also need to increase the fan divisors.
See doc/fan-divisors for more information.
运行后，i8kctl fan 1 1我得到 -1 和 1，但旋转 3 秒后，第二个风扇停止了。我已经安装i8k并lm-sensors安装了，经过一个小时的工作，但发生了这种情况：
