我的 ubuntu 笔记本电脑上的风扇似乎不工作。hardinfo 显示没有温度传感器。我也尝试使用 sudo pwmconfig：
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.
We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
我也尝试
lspci -k | grep -EA2 'VGA|3D',
结果是这样的
