Intel digital thermal sensor...                             Success!
    (driver `coretemp')
Scan for Super I/O sensors

Found `Nuvoton NCT6793D Super IO Sensors'                   Success!

    (address 0x290, driver `nct6775')

probe the I2C/SMBus adapters now? (YES/no): 

Using driver `i2c-i801' for device 0000:00:1f.4: Kaby Lake (PCH)

Module i2c-dev loaded successfully.

Now follows a summary of the probes I have just done.

Driver `coretemp':

  * Chip `Intel digital thermal sensor' (confidence: 9)

Driver `nct6775':

  * ISA bus, address 0x290

    Chip `Nuvoton NCT6793D Super IO Sensors' (confidence: 9)

執行 etc-update，寫入設定檔，其所產生的 /etc/modules-load.d/lm_sensors.conf，。如下

nct6775

要重新編譯 kernel，make xconfig 或 make menuconfig，加上下面兩個 driver module。
在 Device Drivers/Hardware Monitor Support 項目下

Intel Core/Core2/Atom temperature sensor (SENSORS_CORETEMP)
Nuvoton NCT6775F and compatibles (SENSORS_NCT6775)
