[KDE] FN laptop keys not active, until OS is awaken from suspend to RAM

[tjago]

Hi Guys,
I'm not sure if this bug is related to plasma, KDE. or gpu driver itself

What happens:
upon boot, FN keys on laptop Keyboard (Thinkpad E14 Gen 2) do not respond
After Sleep (Suspend to Ram happens), computer wakes up, FN keys work normally.
So weird. It's like that since Kubuntu 20.04, I did upgrade to 20.10, although bug still persists.
Seems something trival..

If I can check something extra in my system, please let me know.

Other notes: my system is using amdgpu driver (Ryzen APGU processor)
Maybe it's causing it?

Any ideas/advices welcome

None of the above, most likely.
For whatever reason, the service or drivers thjat control the fn keys is not loading at boot, so it is unlikely to be a Plasma or GPU issue at all

But it seems a well known issue, with no fix at the moment, and is not specific to any distro, an so far, any kernel version.

This has links to reddit thinkpad related posts on the same topic, that may be useful to look at.

You might try manually loading the kernel module that is responsible for the keys and see if it makes them work, though reports say it does not work.

sudo modprobe -r thinkpad_acpi && sudo modprobe thinkpad_acpi

Oh, that's a good find, should have checked Lenovo forums beforehand. There is actually quite long thread there.
So my experience pointed me to Kubuntu forum as it was only distro I loaded on it. But problem seems to be with vendor.

I gave it a shot, but as you guessed it, that didn't do the trick.

On the linked Lenovo forum you provided, on page 5 there is given workaround to set in cron 2sec timed suspend, and that should work fine for now.
Thanks for the quick reply. Problem solved.
