Re: Lenovo notebook uses function keys to cause system shutdown

Great.
On a limb, is a bogus wmi loaded?

lsmod

Also

Still, even with these changes when fn + f5/12 is pressed, system crashes. The only way to stop crashes is to set acpi=off in kernel parameters.

Re: Lenovo notebook uses function keys to cause system shutdown

Please don't grep, the modules don't all have "wmi" in their name.

Re: Lenovo notebook uses function keys to cause system shutdown

Do I paste all output from lsmod?

Re: Lenovo notebook uses function keys to cause system shutdown

Add this to the https://wiki.archlinux.org/title/Kernel_parameters at the bootloader (you'll lose some functionality for pretty much sure, we for now just want to know whether it prevents the powercuts, but this might inhibit your keyboard entirely, so you want this to be transient)

module_blacklist=button,tiny_power_button,ideapad_laptop,nvidia_wmi_ec_backlight

If this works, allow one by one again, start w/ ideapad_laptop and then"button" - "tiny_power_button" makes me nervous…

Re: Lenovo notebook uses function keys to cause system shutdown

It worked! Looks like the problem was with "ideapad_laptop" module. After blacklisting it, fn keys now work without crashing the system.
Many many thanks for your help!

Re: Lenovo notebook uses function keys to cause system shutdown

You edited the part where the backlight (still) doesn't work.
Was and in case "how" this sorted out?
Do the keys still produce the expectable input w/o the ideapad_laptop module?
(There're more users on this thread who might benefit from this)

Re: Lenovo notebook uses function keys to cause system shutdown

Yeah, I edited the part about the backlight because I was not sure if it is relevant to this specific problem and I did not want to add to confusion.
In my case, all  fn keys produced expected result, except brightness, brightness icon lights (it picks up a fn + f5/6 press signal) but brightness does not change. I suspect that it has to do with something else.
All other functions work.

In an hour or so I will try to boot from live usb with blacklisted module and report results.

Re: Lenovo notebook uses function keys to cause system shutdown

The main question is whether and what events those keys generate in "sudo libinput debug-events" (or "sudo evtest"), maybe "xev -event keyboard"

Re: Lenovo notebook uses function keys to cause system shutdown

For fn+f8 check the impact on rfkill, otherwise you'll just have to bind the keys to some action w/ your shortcut daemon.
Resp "fn + f5 brightness icon shows up but brightness does not change" they probably are (your DE displays some icon), but the attempted backllight function is bogus
https://wiki.archlinux.org/title/Backlight

The very good aspect is that the keys still work, because then all that needs to be done is to get rid of the ideapad wmi for legion notebooks.
If more users can confirm that, this probably should be in https://wiki.archlinux.org/title/Laptop … ion_series - eventually a kernel bug (though this likely ends up in blacklisting the module for your product ID/s will break other notebooks… roll)

Re: Lenovo notebook uses function keys to cause system shutdown

I have a LOQ 16APH8 running Tumbleweed kernel 6.6.3.1 KDE.

A workaround to the brightness being unchangeable is to use the dedicated GPU. I did this by enabling dynamic graphics from the bios and running sudo prime-select offload.
Both the brightness keys and changing the brightness through the GUI work after doing that
Edit: It may not be necessary to keep using the dGPU. I've switch back to the UMA graphics and everything seems to still work.

Disabling ideapad_laptop may prevent TLP from capping battery levels. What I did was boot with ideapad_laptop enabled, let TLP do its thing and then disable both TLP and ideapad_laptop. The battery cap seems to be holding even after multiple reboots.

My laptop would also shut down if it was sleeping and the lid was closed and sometimes if I unplugged the charger. These issues may be specific to this model or my setup.
In any case they were also solved by disabling ideapad_laptop.

Thank you very much seth for figuring this out.
