Enabling CPU Temperature Monitoring

NOTE: Tested in Ubuntu 16-04 w/ Kernel 4.4.72+

The crucial package to install is lm-sensors

The package, however, depends on the coretemp kernel module. To include it, install the linux-image-extras package for your specific kernel version:\ sudo apt-get install linux-image-extra-uname -r``

Then run:

sudo sensors-detect

• When asked if you want to add lines to either /etc/modules or /etc/sysconfig/lm_sensors, select yes
• If installing from source, there are extra steps:

  sudo cp prog/init/lm_sensors.service /lib/systemd/system
  sudo systemctl enable lm_sensors.service
  sudo service lm_sensors restart
  sudo service lm_sensors status
  

Then restart kmod to load the new modules: sudo service kmod restart

• May want to check its status to ensure it successfully restarted (meaning all modules were successfully loaded)
• Can also double-check that coretemp is loaded:

  sudo lsmod | grep coretemp
  

  • If it’s not, see if it exists:

    ls -l /lib/modules/`uname -r`/kernel/drivers/hwmon | grep coretemp
    

  • If it exists, try loading it:

    sudo modprobe coretemp
