Give more information if you have

After i installed this package and tried to configure /dev/video0 it did nothing just flashed webcam light. Then i tried /dev/video1 and it said opencv can not open /dev/video1. I was trying to make howdy work. After it did not work i tried rebooting laptop, also i shutdown and start it, but now the webcamera stopped working. I tried to remove this package but still when i try to use webcamera it's light just flashes like it did when i tried to configure it. I tried modprobe -r uvcvideo and then modprobe it still does not work. This package broke something in my system. What could it be and how can i fix my webcamera?

HERE when i ran configure it did not have ANY output. I still waited for about 30 minutes and then pressed CTRL+C. It stopped. I quickly removed this package shutdown->start camera is broken!

Be patient, do not kill the process (you could break the camera); it is not stuck if you see the Searching... output blinking. If you really have to, press CTRL+C, the tool will stop safely as soon as possible (you may have to answer a last question see 5.).```

I see you do not give the output logs from /var/local/log/linux-enable-ir-emitter/linux-enable-ir-emitter.log. So it is hard for me to understand what exactly happened.

Note the camera is probably not physically damaged, it seems its firmware is in a wrong state.

Yes quickly tried to get that log but file was not there. Here it is. Took just now. Yest it seems like that, because the led is flashing quickly just like it did when i tried to setup ir-emitter. But how can i fix it? I tried updating everything using fwupd, but it did not help.

Hum, you use the package from AUR. I see it also removed the log when you uninstalled the package, so what is inside is pointless now.

Unfortunately, unless contacting the camera vendor/producer, to get the firmware in order to reset, I'm not sure to be able to do something for you, but I will try my best.

Do you still have the file which is inside /etc/linux-enable-ir-emitter ?

[mgite]

Yes there are 2 files

pci-0000:00:14.0-usb-0:8:1.0-video-index0.ini pci-0000:00:14.0-usb-0:8:1.0-video-index1

[EmixamPP]

Could you copy paste their content?

I was searching for fix and i noticed in this video on 3:26 https://youtu.be/d_hucSz3mQI?si=Hlcv8-GeskPfyyVN&t=206

There is RESET button beside camera in Lenovo vantage on windows. Maybe that will fix it? Or maybe it's just to reset brightness and contrast :D But i have not used windows in about 15 years already. I'll have to replace ssd and install windows first.

You can use a VM

So... I have a problem and the log file...

Thanks for the log, I will investigate a possible solution

After turning off the laptop and turning it on again, it came back. Several reboots before that did not help. It was necessary to turn it off and on again.

Fix on Lenovo laptop

Hi, just had the same problem. I left the configuration running unattended for a couple of hours. When i came back the terminal said "Segmentation fault (core dumped)" and the camera no longer appeared when i tried to test it.

What i fixed by turning the computer off and starting it with the NOVO button on my Lenovo laptop and choosing system recovery. After the reboot the camera reappeared and functioned fine.

Pleas note that i booted to Windows while using the recovery function. I don't know how Lenovo's recovery tool works, so i don't know if booting to Linux makes a difference.

[besteFinanzen]

It was necessary to turn it off and on again.

This actually seams to be reproduceable, at least on lenovo laptops. Fixed my camera on my lenovo slim 3 14ahp10 running ubuntu with a shutdown and boot. Rebooting was not enough.

[LainerDonet]

I want to report a very similar case on the same laptop model, which may help narrow down what's causing this.

Hardware/software:

• ThinkPad T480
• Ubuntu 24.04.4 LTS, GNOME 46, Wayland
• linux-enable-ir-emitter 6.1.2 (systemd release variant)

What happened:

The first time I ran sudo linux-enable-ir-emitter configure, the process completed and appeared to work correctly. On the second run, I killed the process manually (kill) partway through. Right after that, I noticed the webcam's white LED stayed permanently on — it did not turn off on its own, and it stayed on through a normal reboot. It only turned off after a full cold power-off (holding the power button until the system powered down completely).

After that point, v4l2-ctl --list-devices started showing the IR camera under a different identity:

Before (working correctly):

Integrated IR Camera: Integrate (usb-0000:00:14.0-5):
/dev/video0
/dev/video1
/dev/media0

After (current state):

SPCA2085 PC Camera: PC Camera (usb-0000:00:14.0-5):
/dev/video0
/dev/video1
/dev/media0

Same USB bus location, different reported name — no longer recognized as the IR camera. A camera app that used to show the IR feed in grayscale no longer shows it at all.

Recovery attempts that did NOT work:

1. Normal reboot
2. BIOS toggle: Security → I/O Port Access → Integrated Camera → Disable, save/reboot, then re-enable, save/reboot
3. Firmware check via fwupdmgr — already up to date, nothing to apply
4. Full power drain: shutdown, unplug AC, remove the removable battery, hold power button ~30s, reinsert battery, cold boot

None of these restored the original device identification.

This matches the warning in the tool about not killing the process mid-run ("you could break the camera") — in my case, killing it seems to have left the camera's onboard controller in a bad state that persists across both software and hardware-level resets. Posting this in case it helps correlate with other reports, or in case anyone has found a way to recover from this state.

[Shlok-Bhakta]

@LainerDonet This literally just happened to me. I did the exact same thing. if anyone with a firmware dump of their working camera could send it, that would be awesome!
