No iio sensors detected on Framework Laptop

Support Kernel
1

I used to run KDE Neon on my Framework laptop, and I had access to my brightness sensor on the path /sys/bus/iio/devices/iio\:device0/in_illuminance_raw
But on Manjaro (6.12.21-4-MANJARO) the path /sys/bus/iio doesn’t even exist.
According to Arch’s wiki, it should work out of the box (wiki archlinux: /title/Framework_Laptop_13#Ambient_light_sensor)
Is Manjaro doing something different ?

Hi @juanito, and welcome!

Have you tried a different kernel? Also, You don’t give much info aout the laptop, so please see:

Please also note and heed: Forum Rules - Manjaro

Those with privacy concerns: note that when -z, or --filter is used, all personally identifiable information is filtered out from the resulting inxi output. :eyes:

Hope you manage!

:bangbang: Tip for legibility: :bangbang:

To provide terminal output, copy the text you wish to share, and paste it here, surrounded by three (3) backticks, a.k.a grave accents. Like this:

```
pasted text
```

Or three (3) tilde signs, like this:

~~~
pasted text
~~~

This will just cause it to be rendered like this:

Portaest sed
elementum
cursus nisl nisi
hendrerit ac quis
sit
adipiscing
tortor sit leo commodo.

Instead of like this:

Portaest sed elementum cursus nisl nisi hendrerit ac quis sit adipiscing tortor sit leo commodo.

Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.

Thereby improving legibility and making it much easier for those trying to be of assistance.

:bangbang::bangbang: Additionally

If your language isn’t English, please prepend any and all terminal commands with LC_ALL=C. For example:

LC_ALL=C bluetoothctl

This will just cause the terminal output to be in English, making it easier to understand and debug.

Please edit your post accordingly.

Note that the above text is partially pre-prepared as a general introduction for new forum users. Please take the time to follow links given and learn how to create effective support requests and encourage quality responses.

Thanks, I’ve updated my initial message with my system info.
I haven’t tried with a different kernel, but I’m going to look into it right now.

first: your bios is from 2022, check the vendor for a bios update and update it if avaiable.
second: enable aur. you’ll find the framework stuff at the aur.
especially these packages:

framework-laptop-kmod-dkms-git
framework-sensors-git

Ok, I updated to latest BIOS 3.20 and installed the 2 packages from the AUR.
After a reboot, I did a rerun of sensors-detect, but nothing new has been added, only coretemp is found.

I also tried to boot on another kernel, 6.12.16_rt9-1 but nothing changed either. Should I try an older kernel ?

If I manually load modprobe cm32181 (cm32181 is supposed to be the name of my ambient light sensor) and run sensors-detect, I see that /sys/bus/iio gets created but it’s only populated with empty files and folders.

is the sensord-daemon active ?

It wasn’t !
There was this error:
/usr/sbin/sensord: error while loading shared libraries: librrd.so.8: cannot open shared object file

After installing rrdtool, sensord starts:

journalctl -xeu sensord.service

However, /dev/sbus/iio hasn’t changed. Any further steps ?

have you already checked the section “ambient light sensors” from
https://wiki.archlinux.org/title/Framework_Laptop_16
and the given links in this article ?
there is also the

is this the correct setting ? you set the acpi-configuration to this windows-2020 behaviour. i’m unsure why you have set this. must it be ? keep in mind there is a new bios on your system now.
i would give it a try to delete this setting from the grub-config and update grub afterwards.

Can’t remember why I put that in grub, from a quick research it used to be advised on Arch Wiki, but not anymore. I’ve removed it, updated grub, restarted, but sadly with no effect :frowning:

I did follow the section on ambient light sensors from arch wiki. I’ve installed iio-sensors-proxy which refuses to run:

> sudo iio-sensors-proxy -r -v
** (iio-sensor-proxy:7088): DEBUG: 11:53:54.630: Starting iio-sensor-proxy version 3.6

** (iio-sensor-proxy:7088): WARNING **: 11:53:54.648: Not a switch [/sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/LNXVIDEO:00/input/input4/../capabilities/sw]

** (iio-sensor-proxy:7088): WARNING **: 11:53:54.648: Invalid bitmask entry for /sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/LNXVIDEO:00/input/input4/event3
** (iio-sensor-proxy:7088): DEBUG: 11:53:54.649: No sensors or missing kernel drivers for the sensors

I don’t know if this is the chicken or the egg. Is iio-sensors-detect supposed to populate /sys/sbus/iio, or does it refuse to run because it’s empty ?

The other tool mentionned in the wiki is illuminanced. It requires to provide the path to the ambient light sensor and instruct to find it with find /sys/bus -name '*illuminance*'. Of course, there’s nothing returned by this command on my system.

sorry that i can’t give more ideas to this specific-framework laptop. i have no framework laptop. but a very good swiss-knife method would be to boot for testing in a live-iso session from a stick and check if the hardware is detected in the live-iso. that could give a first impression if it is a general problem or just a problem with your installed one.

p.s.: just a simple question ? are you on stable ?

pacman-mirrors -G

in this case it’s worth to switch to unstable. check the manjaro-wiki for switching the branches. there is no problem to switch between the branches and the check if the unstable branch works better solves very often hardware-hickups

Thanks for your help !
I tried a few distributions and all of them had iio correctly populated.
I currently have some weird issue linked to hibernation, so I disabled it and oh miracle ! /sys/bus/iio gets populated at last !
sudo systemctl mask hibernate.target is enough to have iio back.
However, now I don’t have hibernation anymore. Unmasking hibernation kills it.

well as said it’s sometimes really helpful to use live-iso’s to check and bringing up some inspirations that help to get on track.
