 Posted: Fri Nov 18, 2022 7:33 pm Post subject: Hardware keys no longer work |
 |
|
| Somewhat recently I did a big kernel config change with the help of someone over irc and (I think) ever since then I can no longer control volume or brightness with the fn keys on my Yoga 720. I have tried to search for codes with xev and xbindkeys -k when I press the keys, but nothing shows up when I press fn or fn+f1 (mute) for example. I can see that the ideapad_laptop module is loaded at boot and the thinkpad_acpi module is not, but swapping those in and out don't seem to help. I have tried setting acpi_backlight to different values when booting as well to no effect. I am not sure what else to try if I can't get the codes to show up. What else can I try? |

Those keys may not generate normal keycodes, but rather acpi events. Does acpi_listen see anything?
I don't know about the yoga series, but at least on older thinkpads one needs thinkpad_acpi loaded and some appropriate acpid handler scripts to get all the function keys working.

| I installed acpid, started it, modprobed thinkpad_acpi, then ran acpi_listener, but pressing the buttons didn't make anything show up, so I guess there are not acpi events being sent. Are there other modules or daemons I need to get this to work? What else could the keys be doing if not sending codes or acpi events? |

Bump.
I am revisiting this and have not been able to make any progress getting events to show up with `acpi_listen`. What else can I try? |

I think it's not thinkpad_acpi, but ideapad_laptop.

Here is my .config: http://dpaste.com/HEMLFAV3Y
I have CONFIG_ACPI on and I have sys-power/acpid on and enabled with the default runlevel. I can see it is running with `pgrep -a acpid` and I can confirm CONFIG_ACPI is y with `zgrep CONFIG_ACPI /proc/config/gz`. I disabled the recommended settings on there, so I think I've done everything right as far as kernel options go.

I just now tried setting CONFIG_IDEAPAD_LAPTOP=m and can confirm that is set with config.gz. I did `modprobe ideapad_laptop` and tried to see events with `acpi_listen` again, but no events were generated. Does it matter if ideapad_laptop is insmoded at boot or not? Could it be something else? |

Oh, this one is with nvidia, mine is with nvidia too and brightness control only worked prior to nvidia driver version 510 and I think somewhere in the 5.18 or 5.19 kernels. Now it only works in hybrid graphics mode.
Try enabling CONFIG_NVIDIA_WMI_EC_BACKLIGHT and if it doesn't work, maybe the nvidia driver is broken. You mention other buttons don't work too? Did you try with a dist kernel or boot live ubuntu for example?

I just tried 525.60.13 and it seems they've fixed the brightness control. However I don't think this has anything to do with your problem.
What I recommend is trying dist-kernel or live Ubuntu or something like that and see if it works there. If it doesn't, maybe the problem is more general.
Best Regards,

I have finally gotten around to testing the dist kernel and I can see that the hardware keys are working again and an unrelated issue with the rtc clock not getting set correctly at boot is also resolved. I did a zgrep -i acpi /proc/config.gz and compared it to the .config of my custom kernel and this is what I found:

I tried enabling CONFIG_THINKPAD_ACPI_VIDEO, but the keys still aren't working. Could it be something not related to ACPI that is preventing this? Or could I be messing something up with module drivers or something? |

This reminds me of why I use dracut instead of genkernel. I never made genkernel produce an initramfs which could enable my touchpad. I don't know why is that, I know genkernel can do some things dracut cannot. but since I'm not a user of such functionality, I don't care.
The way I discovered I needed to try dracut is it was used to produce gentoo-kernel. Btw you can supply gentoo-kernel with custom config and it'll produce kernel and initramfs for you. If you want to go that route, you need to enable savedconfig on gentoo-kernel and place a kernel config in /etc/portage/savedconfig/sys-kerenel named gentoo-kernel. I remember there was something about versioning too, but I think it'll pick it up without a version in the filename and will automatically produce a savedconfig for your particular version once it compiles the first time.
