Fan and Voltage monitoring not showing

[pjmartorell]

Hi, I have been trying your app and even enabling the hardware permissions seems that fans and voltage monitoring is not giving any information. I attach an screenshot. Any idea on how to fix that?
I'm running an Ubuntu 18.04.1 with an Intel® Core™ i7-8550U CPU @ 1.80GHz × 8

Thanks!

sensors-unity is merely a GUI on top of the sensors CLI command, so try running that and see whether it shows you Fans & Voltages.
If not you probably have to run sensors-detect.

I run sensors-detect but seems that it didn't change anything after following all the steps. Here is the output of sensors:

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +48.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +45.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +47.0°C  (high = +100.0°C, crit = +100.0°C)
Core 2:        +48.0°C  (high = +100.0°C, crit = +100.0°C)
Core 3:        +46.0°C  (high = +100.0°C, crit = +100.0°C)

pch_skylake-virtual-0

temp1:        +44.5°C  

Any suggestion on how to fix this?

Thanks!

as you see neither sensors gets any fans or voltages.

sensors-detect might have requested a new kernel module to be loaded - for this you need to reboot.

Otherwise you should research which sensor chipset is on your mainboard and try to get it running. Might be this one https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1740736

marking invalid as it is not GUI related

Thanks for your help. This are the steps I followed to make it work:

1. I installed i8kutils: sudo apt-get install i8kutils
2. Add "i8k" on a new line in /etc/modules
3. Load the module with sudo modprobe i8k force=1

THe otuput of sensors now is:

pch_skylake-virtual-0
Adapter: Virtual device
temp1:        +41.0°C  

acpitz-virtual-0
Adapter: Virtual device
temp1:        +25.0°C  (crit = +107.0°C)

dell_smm-virtual-0
Adapter: Virtual device
Processor Fan:    0 RPM
CPU:            +42.0°C  
Ambient:        +36.0°C  
Other:          +32.0°C  
Other:          +37.0°C  

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +45.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +45.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +44.0°C  (high = +100.0°C, crit = +100.0°C)
Core 2:        +45.0°C  (high = +100.0°C, crit = +100.0°C)
Core 3:        +43.0°C  (high = +100.0°C, crit = +100.0°C)

Now I'm not able to understand which are the real temperatures. dell_smm-virtual-0 and coretemp-isa-0000 have different temperatures.
