Ambient Light Sensor not works

[zbyhu]

Hi guys,


CachyOs linux distro is great for my notebook, but i have struggle with one thing.


Ambient Light sensor (ALS) not works for me. I Want to use screen brightness adjustment depends on ALS.


‘cat /sys/bus/iio/devices/iio:device0/in_illuminance_raw’ return always 0.


One courious thing is that On LiveUsb Installator demo, when i open terminal and read in_illuminance_raw then it returns proper values (e.g 200, 300 seems it works). But Installed version never works. I have tested various linux distro and this feature never works.


Did you guys have any idea how to make it works?


My notebook is ASUS nx500jka.


Thanks!

you could try and disable - wluma - to see if your ALS starts working

to disable it - note: you may need sudo at the beginning

systemctl stop wluma

then run

systemctl disable wluma

reboot

if it does not work then simply enable it

systemctl start wluma

systemctl enable wluma

i dont have such service.
'Failed to disable unit: Unit wluma.service does not exist'
Anyway sensor read not works even if i disable this feature (Auto-screen-brightness) in Plasma environment.
Im wonder why it works on live-usb demo.

Have a look here if you are running KDE Plasma desktop

I really like Arch-deriratives such as Antergos, but I am missing the feature which automatically adjusts the screen brightness... There are programs which...

I could be way off the mark, but it sounds like missing firmware to me....
