SUMMARY After waking from sleep, the keyboard backlight is off (it doesn't restore the previous brightness) and I am not able to increase the brightness using FN+F2 as I normally would before sleep. STEPS TO REPRODUCE 1. Sleep 2. Wake 3. Attempt to increase keyboard brightness via FN+F3 OBSERVED RESULT Keyboard backlight is off after waking, and I am no longer able to change the keyboard brightness via function keys. However, I am able to do so via `echo 3 > /sys/class/leds/asus::kbd_backlight/brightness`. EXPECTED RESULT The keyboard brightness should be restored to the same value as before sleep. In addition, I should be able to control the keyboard brightness using the function keys after waking from sleep. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Gentoo Linux x86_64 (kernel 6.9.5) (available in About System) KDE Plasma Version: 6.1.0 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.2
I should also comment that Plasma 5 also did not remember my keyboard brightness after waking, but I was able to set it using the function keys.
If you restart powerdevil service with `systemctl --user restart plasma-powerdevil.service` does it work as before sleeping?
I have OpenRC so I'm not sure what the equivalent command is. I did run `/usr/libexec/org_kde_powerdevil --replace` and it looks like it is running, but it did not correct the keyboard backlight.
Has this problem been solved at the moment? Sometimes the keyboard backlight is restored after waking up. But usually not. It seems that something is blocking the recovery of the backlight state. IMHO this linked with kernel/firmware updates. KDE powerdevil is not updated from 04/2024. Operating System: Ubuntu 22.04.5 LTS (Jammy Jellyfish) KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.114.0 Qt Version: 5.15.12 Kernel Version: 6.8.0-48-generic (64-bit) Product Name: Asus ZenBook UX435EAL
I am still having this problem. I recently updated to Plasma Version 6.2.4, Frameworks Version 6.9.0, Qt Version 6.8.1, kernel 6.12.6-gentoo. I am also still using X11 (xorg-server-21.1.5). When I first re-open the lid, the keyboard light is actually on but then turns off as the system resumes from sleep.
I just got the same problem, but for the screen brightness. Operating System: Manjaro Linux KDE Plasma Version: 6.2.4 KDE Frameworks Version: 6.8.0 Qt Version: 6.8.1 Kernel Version: 6.12.4-1-MANJARO (64-bit) Graphics Platform: X11 The command systemctl --user restart plasma-powerdevil.service does fix it.

Let's keep this bug report about the keyboard brightness; an issue with the screen brightness will probably be caused by something else. If you can still reproduce that in Plasma 6.3.4 or later, please open a new bug report for it and relate it to this one by pasting "489056" into the "see also" field of the new bug report. Thanks!
Is this still happening in Plasma 6.3.4 or later?
(In reply to Nate Graham from comment #8) > Is this still happening in Plasma 6.3.4 or later? Yes. Still happening for me. I have plasma 6.3.4, frameworks 6.13.0, qt 6.8.3, kernel 6.14.4
I'm not able to reproduce this with a Dell XPS 17 Setup: Keyboard backlight at 100% Steps to reproduce: 1. Put the system to sleep, wake it up Expect: The keyboard backlight is on at 100% - ok 2 . Attempt to adjust the keyboard backlight with the keyboard key Expect: It is adjusted - ok
I have an ASUS ROG Zephyrus M16 (GU604VZ) laptop from 2023.
This issue was fixed for me, I think, in Plasma 6.3.4 or 6.3.5. And it continues working just fine in Plasma 6.4 Beta.
(In reply to abulhair.saparov from comment #9) > > Yes. Still happening for me. > > I have plasma 6.3.4, frameworks 6.13.0, qt 6.8.3, kernel 6.14.4 I have Frameworks 6.15.0, and re-tested on git-master that might be the difference. Can you update frameworks and let us know if the bug persists on your ASUS ROG?
I did update to plasma 6.3.5 and frameworks 6.14.0 and found that the keyboard brightness controls do work after waking from sleep, but the brightness itself is set to 0 after waking. I don't think frameworks 6.15.0 is available on Gentoo just yet, but I can test it once it does become available.
Ah, that's a different issue. Sounds like the original one has been fixed now! If you'd like to report the new issue, please open a new bug report for it. Thanks a lot!
