Keyboard backlight sometimes does not turn on after sleep #1676

nicklascarnegie · 2018-12-23T17:10:11Z

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 #1675.

Downgrading to 12.1.0 resolves the issue.

The text was updated successfully, but these errors were encountered:

I can confirm this bug, after downgrading to the official non-beta version the keyboard backlight is okay now.

joshua6six · 2019-01-21T21:30:46Z

Same here - it was driving me nuts and I was considering bringing my macbook for a repair, but then I started turning all apps that utilize keyboard off and voila. It's interesting how Karabiner is able to interfere with the backlight at all?

jaconey · 2019-02-07T09:55:07Z

Can anyone confirm this is fixed in 12.2.0? I've been prompt to update. Without confirming there's no regression, I'm going to skip the update for now.

AFAIK it has not been fixed. It was not part of the release notes, and this issue is still open.

Thanks for letting me know.

The bug appears to be in 12.1.xxx Beta as you reported. I can confirm backlight works fine after sleep in stable 12.1.0 (version I'm using), so it's introduced between 12.1.0 and 12.2.0. I think it's safe to skip 12.2 then.

joshua6six · 2019-02-07T15:28:21Z

So its either working caps lock LED light or backlight - not both.

what about after the new mojave updates?

Could you point to something more specific that would be related to this particular issue?

currently on Karabiner v12.2 with the new Mojave updates on v10.14.3, keyboard backlight still doesnt work after wake from sleep. Device is a 2018 Macbook Pro 15 inch

rvw · 2019-02-15T21:11:16Z

I have the same problem, very annoying. Karabiner v12.2.0, Mojave 10.14.3 on a 2018 Macbook Pro 15 inch.

davfox · 2019-02-19T19:59:26Z

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.

hadleyac · 2019-02-21T03:24:07Z

I'm having the exact same symptoms as @davfox . Keyboard also unresponsive after trying to quit to fix the backlight.

jschuur · 2019-02-21T06:07:10Z

Same problem in 12.2.0 on a 2018 13 inch MBP with Touchbar.

jonfairman · 2019-02-21T19:39:45Z

Same behavior for me: keyboard backlight doesn't work, quitting Karabiner will fix issue but often will cause the keyboard to become non-functional until I reboot.

Karabiner 12.2.0
macOS 10.14.3
2018 15" MacBook Pro

MHX792 · 2019-02-22T06:25:05Z

Same here. Please fix this. :(

mblode · 2019-02-23T05:48:49Z

Same here! I just got my laptop replaced by Apple because I thought that the keyboard backlighting was broken (The laptop was only 3 weeks old). Glad I have finally tracked down the issue 👍

dakshj · 2019-02-24T21:17:45Z

Seeing the same issue on my 2018 15" MBP as well. Hoping there's a fix for this soon! Thanks.

OrestTa · 2019-02-24T21:38:43Z

Also affected, MBP 15" 2018.

I'm experiencing the exact same issue. The keyboard doesn't respond whatsoever when I quit karabiner and than starts working again after restarting it.

efrandi · 2019-02-27T17:15:29Z

I'm affected by the exact same issue as described by everyone above.

Karabiner 12.2.0
macOS 10.14.3
2018 15" MBP

The only solutions right now are to either (1) stop using Karabiner entirely or (2) reboot every time after wake from sleep to get the backlighting back.

nicklascarnegie · 2019-02-27T17:20:21Z

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?

ksenchy · 2019-03-01T19:30:03Z

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

marinosoro · 2019-03-01T19:35:35Z

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.

Thanks, I will try that one.

ksenchy · 2019-03-02T17:13:01Z

You are correct 12.1.0 works fine apart from the caps lock LED not showing. I can live without that LED

DrianHillman · 2019-03-12T23:01:31Z

I'm effected by this issue as well— uninstalling for now & keeping watch for an update.

mcmillion · 2019-03-14T03:34:34Z

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

CoskunSunali · 2019-03-29T19:31:25Z

~~I am having this issue on Mojave 10.14.4.~~

It doesn't occur anymore, don't know how it was fixed.

ethanchen · 2019-03-30T14:06:05Z

SpaceFn do not works after upgrade system to 10.14.4

mganahl · 2019-04-03T00:18:11Z

Same issue here, macbook pro 2018 (touchbar), mojave 10.14.3

medington · 2019-04-03T04:35:41Z

Just one additional data point here. I can reproduce this issue consistently on a 2018 MBP with a touchbar using 12.2.0 but on a 2015 MBP I don't see the problem at all. Downgrading the 2018 MBP to the lates 12.1 resolved the issue on that computer.

If I can help debugging this issue please let me know!

nyuwec · 2019-04-13T18:20:12Z

I have the same issue what @davfox described (#1676 (comment))

I have a MBPro 15'' 2018 with macOS 10.14.4

Caps lock led works fine.
Backlight can not be turned on and it does not turn on automatically.
Quitting Karabiner makes my keyboard unresponsive, but does not help with the backlight issue.

nicklascarnegie · 2019-04-13T18:31:03Z

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

nicklascarnegie · 2019-04-30T22:32:36Z

I have been running 12.3.0 for a day and a half now and so far no issues with the backlight.

nicklascarnegie · 2019-05-01T07:23:20Z

Closing as latest version 12.3.0 solves the issue.

mcmillion · 2019-06-13T03:36:00Z

This bug appears to be back in 12.5.0.

OrestTa · 2019-07-02T11:57:46Z

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

keyvchan · 2019-07-02T13:59:47Z

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

Version 12.5.0 works fine for me.

mcmillion · 2019-08-27T02:14:15Z

Still broken in 12.6.0 on 10.14.6

Can confirm that rolling back to 12.3.0 and the backlight works after waking from sleep.
