[BUG] The clight does not change the screen light

Hi! As you can see, your verbose log file is telling you the issue:

Paused as no sensor is available.

It means that clightd cannot find a sensor to use. What kind of sensor are you trying to use?

[RezaSh13]

I use the webcam as a sensor And I know it works

[FedeDP]

Did it work leaving devname clight option commented? Ie: when not specified, clightd will use first sensor it finds.

And, what is output of busctl call org.clightd.clightd /org/clightd/clightd/Sensor org.clightd.clightd.Sensor IsAvailable "s" ""?

So, the issue here is that clightd is filtering out your webcam. Can you share output of systemctl status clightd.service --all?

        [0]: 'MJPG' (Motion-JPEG, compressed)

[FedeDP]

Unfortunately Clight does not support MJPG capture; it only supports either GreyScale or YUYV422. I will look into supporting MJPEG in Clightd.

These are my issues, the clight work fine

This is not just my problem, my friend also has a similar problem, Need more information?

[FedeDP]

Can your friend run v4l2-ctl --list-formats too? Thank you very much!

Clightd did not really bother to check supported video format until recent releases; may be it "worked" for you by using YUYV/Grayscale algorithm on a compressed video format (MJPEG)? It worked in the sense that it returned some numbers; but it was obviously wrong. You can see here the commit that added the new check on supported video formats; it was part of clightd 4.0 release.

Mmh it should work fine for your friend; can you attach a verbose log for him/her too?

[FedeDP]

Please note that supported camera pixelformats are found here: https://github.com/FedeDP/Clightd/wiki/Sensors#camera.

He said that the screen light does not change and Installed the git version (But he did not restart, only activated the service)

Can he update his clight-git and test again?

[FedeDP]

Hi! I have some good news for you: latest clightd-git does now support jpeg webcam captures, thus it should work for you :) Let me know (i already tested mjpeg capture on my xps btw)!
