Give more information if you have I can see IR emitter turn on and step-wise increase intensity as different configuration are applied, but it never blinks. In the manual mode it can blink only one time.
Additional info
- Computer (or camera) model: Lenovo IdeaPad Pro 5 14AHP9
- Linux distribution: Ubuntu 25.04
- Version of linux-enable-ir-emitter: 6.1.1
sudo linux-enable-ir-emitter tweak , enter 12, then input 1 3 2 0 0 0 0 0 0
After that, maybe you will see your emitter blinking
sudo linux-enable-ir-emitter tweak, enter 12, then input 1 3 2 0 0 0 0 0 0After that, maybe you will see your emitter blinking
This worked! ✨ Thanks a lot for such a fast response!
There is only one issue left, which is that I need to run sudo linux-enable-ir-emitter run every time after using the IR emitter to see the blinking again.
Do you really mean each time you are using the IR emitter or you are putting the computer to sleep? Because for that, you also need to enable the linux-enable-ir-emitter systemd service as explained in the readme
Each time with no sleep in-between. For example when I run sudo howdy test the IR emotter blinks, then I stop the test and directly start it again, then there is no blinking unless I ran sudo linux-enable-ir-emitter run beforehand.
After I restart the machine the IR emitter works directly, but again after a single use I need to rerun sudo linux-enable-ir-emitter run for IR emitter to work.
Resolving that issue is unfortunately not that easy, since I am hitting the user api limitation offered by Linux, this mean that I will need to provide a Kernel solution. I am currently working on and searching a good and sharable way to do it, when I have time.
Some people simply setup a script that execute the run command every X minutes/secondes. But I agree that is more a trick than a proper solution.
For the ones who are looking for a solution, this how I solved the issue with Systemd:
-
Check if you have a Service Unit. There should be file
/etc/systemd/system/linux-enable-ir-emitter.servicewith:
[Unit]
Description = enable the infrared emitter
After = suspend.target sleep.target hybrid-sleep.target hibernate.target suspend-then-hibernate.target
[Service]
Type = oneshot
ExecStartPre = modprobe uvcvideo
ExecStartPre= sleep 1
ExecStart = linux-enable-ir-emitter --verbose run
[Install]
WantedBy = multi-user.target suspend.target sleep.target hybrid-sleep.target hibernate.target suspend-then-hibernate.target
-
Create a Timer Unit. Create file
/etc/systemd/system/linux-enable-ir-emitter.timerwith:
[Unit]
Description = Timer for enabling the infrared emitter every 15 seconds
[Timer]
OnUnitActiveSec=15s
Unit=linux-enable-ir-emitter.service
AccuracySec=1s
[Install]
WantedBy=timers.target
3. Enable and Start the Timer
sudo systemctl daemon-reload
sudo systemctl enable linux-enable-ir-emitter.timer
sudo systemctl start linux-enable-ir-emitter.timer
Now every 15 s linux-enable-ir-emitter run will be rerun and the emitter will blink even without suspending or restarting the laptop.
I assume you are using it in combination with Howdy
In all file returned by grep -rl howdy /etc/pam.d, add the following line before the one mentioning "howdy":
auth optional pam_exec.so /usr/local/bin/linux-enable-ir-emitter run
Hey there. I have got virtually the same camera as vonaviv (at least my outputs from sudo linux-enable-ir-emitter tweak, v4l2-ctl --list-devices, for dev in /dev/video*; do echo $dev && v4l2-ctl -d $dev --list-formats-ext; done and ls -l /dev/v4l/by-path are the same) although I have a Lenovo Yoga 7 2in1 14AHP9.
I am able to get the IR Emitter to turn on, by modifying instruction 8 with the tweak command. However I am unable to get to a "blinking" state.
Also replecating the settings from vonaviv did not work unfortunately :/
Any ideas on what I could try?
Here is my output from linux-enable-ir-emitter tweak

@Stretox you can try:
In the tweak command, enter 12, then 1 3 2 0 0 0 0 0 0, if the video preview is blinking, enter 12 again, and type start (to enable it when linux-enable-ir-emitter run is executed, e.g. by the systemd service or with my comment about howdy and pam above)
OMG Thank you so much. Didn't realize I needed to do this. You are a Wizard! 🧙
Ahah no problem! Mostly because I saw so many camera instructions since I started this project 😄
