我安装lm-senosrs并运行了sudo sensors-detect。这是我得到的结果：
# sensors-detect revision 6284 (2015-05-31 14:00:33 +0200)
# System: Gigabyte Technology Co., Ltd. Z390 GAMING X [Default string]
# Board: Gigabyte Technology Co., Ltd. Z390 GAMING X-CF
# Kernel: 5.3.0-42-generic x86_64
# Processor: Intel(R) Core(TM) i7-9700K CPU @ 3.60GHz (6/158/12)
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
Module cpuid loaded successfully.

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
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... Yes
Found unknown chip with ID 0x8688

Trying family `National Semiconductor/ITE'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No
Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): yes
Probing for `IPMI BMC KCS' at 0xca0... No
Probing for `IPMI BMC SMIC' at 0xca8... No
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): yes
Probing for `National Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM79' at 0x290... No
Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No
Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): yes
Found unknown SMBus adapter 8086:a323 at 0000:00:1f.4.
Sorry, no supported PCI bus adapters found.
Next adapter: NVIDIA i2c adapter 1 at 1:00.0 (i2c-0)
Do you want to scan it? (yes/NO/selectively): yes
Next adapter: NVIDIA i2c adapter 2 at 1:00.0 (i2c-1)
Do you want to scan it? (yes/NO/selectively): yes

Do you want to scan it? (yes/NO/selectively): yes
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `coretemp':
* Chip `Intel digital thermal sensor' (confidence: 9)
To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!
Do you want to add these lines automatically to /etc/modules? (yes/NO)yes
Successful!
Monitoring programs won't work until the needed modules are
loaded. You may want to run '/etc/init.d/kmod start'
to load them.
Unloading cpuid... OK
当我跑步时sensors我得到：
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.
我尝试过重启，但没有用。运行也/etc/init.d/kmod start没有用。
我试过了，psensors但似乎无法看到 CPU 核心温度。我还尝试使用Python名为 的库读取温度psutil，但它也看不到 CPU。
>>> import psutil
>>> psutil.sensors_temperatures()
{'acpitz': [shwtemp(label='', current=16.8, high=18.8, critical=18.8), shwtemp(label='', current=27.8, high=119.0, critical=119.0)]}
我也尝试过注释掉blacklist i2c_i801并/etc/modprobe.d/blacklist.conf重新启动但没有任何效果。
答案1
跑步：
sudo apt install linux-modules-extra-"your.kernel.here"-generic
用你的内核版本替换"your.kernel.here"，不带引号。
答案2
问题是由于coretemp我的当前内核没有正确安装。
$ locate coretemp
/home/admin1/Downloads/linux-hwe-5.3.0/Documentation/hwmon/coretemp.rst
/home/admin1/Downloads/linux-hwe-5.3.0/drivers/hwmon/coretemp.c
/lib/modules/4.15.0-101-generic/kernel/drivers/hwmon/coretemp.ko
/lib/modules/5.3.0-40-generic/kernel/drivers/hwmon/coretemp.ko
/usr/src/linux-headers-5.3.0-40-generic/include/config/sensors/coretemp.h
/usr/src/linux-headers-5.3.0-42-generic/include/config/sensors/coretemp.h
/usr/src/linux-headers-5.3.0-53-generic/include/config/sensors/coretemp.h
我没有找到coretemp.ko适合我当前内核的版本5.3.0-42。因此我改用5.3.0-40https://meetrix.io/blog/aws/changing-default-ubuntu-kernel.html
答案3
对我来说，问题很简单，你必须要跑sudo /etc/init.d/kmod start。但sensors-detect没有说什么sudo。
