Karabiner-Elements: Keyboard backlight sometimes does not turn on after sleep

Sometimes after sleep the keyboard backlight does not turn on. I can’t say exactly from which version this started to happen, but it’s pretty recent. It might correlate with the 12.1.56 beta which is mentioned in this issue https://github.com/tekezo/Karabiner-Elements/issues/1675.

Downgrading to 12.1.0 resolves the issue.

I think we have plenty of reports now stating more or less the same thing. Perhaps a thumbs up on the original problem statement is enough now, if you have the same problem?

Same issue for me. 2018 MBP 15 inch, Mojave 10.14.3. Karabiner-Elements 12.2.0

After waking from sleep just now, I noticed that the keyboard backlight wasn’t working. I quit Karabiner but then found the keyboard didn’t work at all. Unresponsive to keypresses and the caps-lock light was dead. I ran Karabiner again and the keyboard works again.

The backlight remains not working since the machine woke from sleep. I think i’ve noticed this since last Mojave update but can’t be sure. I have to reboot to get the backlight working again.

Does anybody know which version of this tool can be used to not be affected on MBP 15" 2018 10.14.3?

I downgraded to version 12.1.0 on my MBP 13" 10.14.3 a few days ago and so far I haven’t had the issue anymore.

Can anyone confirm whether there’s a regression in 12.5.0?

@tekezo let us know if we can help debug the issue. Quite a few people now affected by this.

I tried 12.1.0 but still having the same issue on Mojave 10.14.3
