风扇控制不工作

我的笔记本电脑风扇现在不工作了。

我想控制它。sensors命令不显示风扇速度。

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): yes

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): yes
/dev/port: Operation not permitted

Some hardware monitoring chips are accessible through the ISA I/O ports.                                                                                                                        
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no):

这是您的（第一个）问题：Operation not permitted。这可能是因为启用了安全启动。请尝试按照此处的步骤将其禁用。 Ubuntu 16.04 - 如何禁用安全启动？
