Give more information if you have

I'm having a weird issue that may not be directly linked to linux-enable-ir-emitter. I am dual booting windows and Arch, and after booting into windows and using facial recognition there, the next time I boot Arch, the IR emitter doesn't work. The service always fails when booting Arch whether I'm coming from windows or not. If I manually run linux-enable-ir-emitter, although the service still fails, the IR emitter works until I boot into windows again.

Let me know if you need any other information, Thanks!

Additional info

WebF1yin commented 6 months ago

An update, if it matters: holding the power button to force the computer to shut down, from what seems like any screen in either OS, fixes the IR emitter in Arch as well.

Hum, it seems that the v4l paths are not yet setup

Output of linux-enable-ir-emitter boot status after running systemctl start linux-enable-ir-emitter.service

And here, this is a problem to deserialize the configuration file.

You forgot the * here:

cat: /etc/linux-enable-ir-emitter/: Is a directory

Also, could you provide the output of ls /etc/linux-enable-ir-emitter?

EmixamPP commented 6 months ago

I've pushed a possible fix to the error, please try #169. There is an automated comment in the end of PR that provides the tarball.

This should solve the second problem; the one not immediately after boot. Simply execute linux-enable-ir-emitter -v run to see if it succeeds to run the configuration saved (i.e. this is the command executed by systemctl start linux-enable-ir-emitter).

WebF1yin commented 5 months ago

Sorry I left you hanging for so long. This fix seems to work! It still fails to start the service on boot, but linux-enable-ir-emitter -v run or systemctl start linux-enable-ir-emitter makes the emitter work again. If the latter command is used, systemctl status reports the service ran fine.

EmixamPP commented 5 months ago

Great. For this problem, could you try if works for you by adding some delay in the /etc/systemd/system/linux-enable-ir-emitter.service file: 

...
[Service]
ExecStartPre=/bin/sleep 2
...
EmixamPP commented 5 months ago

Oops, the issue was closed by mistake

WebF1yin commented 5 months ago

Adding the delay worked! The service seems like it starts properly every time, and the IR emitter works at the login screen. Thanks so much!

EmixamPP commented 5 months ago

Could you try if 1sec is sufficient? I'm thinking to integrate this delay for everyone
