LG gram style 16" backlight keyboard stopped to work after installing kernel-core-6.9.7-200.fc40.x86_64

The last working kernel was: kernel-core-6.9.6-200.fc40.x86_64 also the Fn keys to increase/decrease the screen brightness stopped to work as well if I try to activate the keyboard backlight using the Fn key, it works but if I try to make it work clicking the keyboard option on the upper right corner menu, nothing happens (image attached for reference), if I manually select kernel 6.9.6 all works fine. The newest kernel is the 6.9.10 and the issue persists. I’m actually new in this topics, I want to stay in Linux, I have been trying to see how to troubleshot this but not sure, if you could provide me with the how to it would be much appreciated.

Thanks in advance for all your help.

Hi there. From the screenshot I see (presume) you’re using GNOME Shell extensions. Could you try testing your issues with extensions disabled?

Hello guys!

I can confirm the same issue.

Tried no extensions, different kernels from 6.9 to 6.10 and the issues still there.

No brightness (FN+BRIGHT) works.

Battery driver does not work.

Downgrading to kernel 6.8.5-301.fc40.x86_64 and all looks to works fine.

My laptop is LG Gram 16ZB90R.

So, I’m waiting for newest kernels (may be on fedora 41) to see what happens.

Hello.

I confirm the problems with other LG models. I have a LG13.

Fn +
F1 executes LG control center (not recognized) => can not attribute to gnome control center
F2 decreases LCD brightness (STOPPED TO WORK)
F3 increases LCD brightness (STOPPED TO WORK)
F4 run the mode defined in windows (STOPPED TO WORK) => can not attribute to lock screen or sleep
F5 enables / disables touchpad (STOPPED TO WORK)
F6 enables / disables ariplane mode (OK)
F7 switch monitor (currently no 2nd display to test it) => previously worked
F6 enables / disables keyboard lighting mode (OK)
F9 switches to reader mode (not recognized)
F10 mute (OK)
F11 turns up the volume (OK)
F12 turns down the volume (OK)
Prt Sc works as the scroll lock (not recognized)

Regards
