Show Lenovo Yoga 730 fan speed in Kubuntu
After a bunch of digging and investigation for the Super I/O chip used by the LNVNB161216 motherboard, it seems that the fan speed is neither exposed nor controllable by any operating system. The chip in question is from Nuvoton and operates independently.
for other models, you can try this:
You may need to make some changes to your /etc/default/grub
, then run sensors-detect
again. Try this:
- Edit
/etc/default/grub
as rootsudo vi /etc/default/grub
- Add/Edit the
GRUB_CMDLINE_LINUX
value so that it reads:GRUB_CMDLINE_LINUX="acpi_enforce_resources=lax"
- Save the file and close
- Update Grub with
sudo update-grub
- Re-scan the hardware with
sudo sensors-detect
The fan speed should now be visible when using applications that display this data.
