Give more information if you have IR camera (/dev/video2) flashes briefly for about half a second and then stops working showing only a black screen in the preview. This happens everytime it is llaunched. One time I forgot to close a camera app that was using the normal webcam, on that occasion the ir camera was warking fine and can consistently reproduce this. I'm new-ish to Linux so my apologies if something is missing, let me know if you need anything else :)

Additional info

Computer (or camera) model: HP Envy x360 15-fh0002nl, sometimes known as fh0000 or fh0xxx
Linux distribution: Ultramarine Linux 40, based on Fedora 40
Version of linux-enable-ir-emitter: 6.0.3

Sep 28 '24 02:09 madesho

Execute

sudo linux-enable-ir-emitter -v tweak
input 2
input 1 3 2 0 0 0 0 0 0
look at the video feedback and the ir emitter, does it work?
if not retry with 1 3 3 0 0 0 0 0 0
does it work?
if not paste output here

Seems that I can't change the configuration, am I doing something wrong?

Sep 28 '24 13:09 madesho

Could you retry with the new v6.0.4? I think it should work now; I fixed a bug that you reported here!

Sep 30 '24 19:09 EmixamPP

I tried to uninstall the old version and installed the new one and the camera was working correctly without changing any setting for some reason? Then I installed Howdy and it did the same thing that I described the other day with a few flashes and then the black preview. Went back to try with your solution of the other day and now it changes the settings correctly, but it still doesn't work properly. Also tried to uninstall Howdy and its dependencies to see if was some kind of conflict with something, but the problem is still there

Sep 30 '24 21:09 madesho

First using the tweak command assign the value 1 3 2 0 0 0 0 0 0 to the instruction 0 Then exit and:

execute linux-enable-ir-emitter -d /dev/video2 test does the emitter flash?
execute linux-enable-ir-emitter -d /dev/video2 test does the emitter flash?
execute linux-enable-ir-emitter run
execute linux-enable-ir-emitter -d /dev/video2 test does the emitter flash?
execute linux-enable-ir-emitter -d /dev/video2 test does the emitter flash?

We will determine if the applying of the instruction is permanent or not

Oct 02 '24 17:10 EmixamPP

Sorry for the late answer, followed your instructions and it's the same thing as always, some flashes and then black screen

Oct 07 '24 20:10 madesho

I made a discovery, I am running into the same issue and if you run the command sudo linux-enable-ir-emitter test

and keep it running and play with your hand across the camera/sensor area it will blink again, if you remove your hand it will unblink, this is also true for the assus zenbook S16 UM5606. I know the asus machine has a proximity/motion sensor that is suppose to wake up the device when you come back from washroom/break/whathaveyou. Could it be turning off the emitter as a power saving move

@zkurdi45 could be something that may disable using the tweak command, see readme

Feb 16 '25 10:02 EmixamPP

Same issue here, changine values didn't really do anything. My laptop is ASUS ProArt PX13

Aug 28 '25 00:08 Yach0

Same issue here with an ASUS Pro Art H7606WX-DRSE011X.

I'm willing to help troubleshooting the issue, but I really don't understant what changing the tweak values is supposed to do.
