I can't seem to install driver for my Lenovo Laptop fans

useraddition · 2026-09-07 15:32:44

Hi I'm having a problem, I installed a program from aur 'LenovoLegionLinux' it is the fan driver. It requires 'pwmconfig' and 'fancontrol' I have both pwm and fancontrol and I can't generate pwmconfig file, it's not letting me. These are my specs I tryed finding reference on the web and I can't find any substantial documentation.

$ sudo legion_cli fan-unlock-enable
Traceback (most recent call last):
  File "/usr/bin/legion_cli", line 8, in <module>
    sys.exit(main())
             ~~~~^^
  File "/usr/lib/python3.14/site-packages/legion_linux/legion_cli.py", line 512, in main
    legion = LegionModelFacade(expect_hwmon=not args.donotexpecthwmon)
  File "/usr/lib/python3.14/site-packages/legion_linux/legion.py", line 1532, in __init__
    self.fancurve_io = FanCurveIO(expect_hwmon=expect_hwmon)
                       ~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3.14/site-packages/legion_linux/legion.py", line 797, in __init__
    raise FileNotFoundError("hwmon dir not found")
FileNotFoundError: hwmon dir not found
$

So I found this documentation site on my driver and tryed to follow the wiki
https://github.com/johnfanv2/LenovoLegi … /README.md

so then i did 'pwmconfig' and got this error:

$sudo pwmconfig
# pwmconfig version 3.6.2
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

/usr/bin/pwmconfig: There are no pwm-capable sensor modules installed
$

So now I'm stuck and my laptop has been getting hot and I really need to get my fans going:

This is my specs:

Things to do fast: fully power off laptop, unplug charger for few minutes, reset bios to defaults and once again fully power off laptop, unplug charger for few minutes...
If that don't help, find out how to reset your laptop cmos on motherboard; maybe there is some way (key shortcuts when boot or something else), so you don't have to disassemble your laptop.

What display command 'sensors'?

That "LNV" model is not in the allowlist for that driver, you can force to load the driver, but some features could not work better to ask the driver maintainers to add support for your laptop model.

useraddition · 2026-09-09 01:09:13

Yes, thanks for bringing that to light for me, I kind of figured that. It turns out I have Lenovo 'Yogafan' it's a different model, I need to uninstall Lenovo Linux and find another package... more to come... I will post more specs in the near future... sorry for being rude not responding soon enough. Thanks.

Mod note: moving to AUR Issues

Ok so my fan shows now in dmesg I'm showing the module loaded. I did something this is what I did:

I blacklisted 'yogafan'

and I did this:

# vim /etc/modules-load.d/legion-laptop.conf
options legion-laptop force=1

#vim /etc/modprobe.d/legion-laptop.conf
options legion-laptop force=1

This is the output of dmesg:

#dmesg

So it's showing in sensors modules loaded correctly and the fan increased, on it's own. I think it's locked on auto though. That's why I can't adjust them manually which I'm trying to do.
So I saw somewhere I have to unlock the fan to adjust values manually, this is the command for that:

sudo legion_cli fan-unlock-enable
ERROR:Command not available because feature is not available or kernel module is not loaded.

I'm going to reboot my system now and see if that changes anything. Anybody can chime in with things to say, Thanks.
