[SOLVED] Media controls have stopped working after recent updates

After a system and firmware update yesterday I noticed the XF86AudioRaiseVolume, XF86AudioLowerVolume, XF86AudioMute keystrokes are no longer being registered on my external keyboard.

The keyboard: Lenovo SK-8823
The laptop: ThinkPad T480

I have those inputs bound to pactl commands via xbindkeys. The keybinds don't work anymore. I checked if my laptop even sees the keystrokes with xbindkeys --key and it turned it doesn't. Hitting the key combos (Fn + F1-3) doesn't trigger any event as far as xbindkeys --key is concerned.

I have ensured that it's not an issue with the keyboard itself as the media keys work on other laptops as well as desktops.

How does one troubleshoot the issue further?

Thanks.

Edit: The media keys on the laptop keyboard are working fine. The issue is related to an external keyboard only.

Re: [SOLVED] Media controls have stopped working after recent updates

In case it makes it easier to narrow the issue down, here is the journalctl output when I connect the keyboard:

Re: [SOLVED] Media controls have stopped working after recent updates

I'm expereincing this bug with my Lenovo SK-8823 though it had worked well before. Media keys are invisible for xev and other apps.  At the same time Lenovo KU-1255 works well. Does anybody have any ideas?

Re: [SOLVED] Media controls have stopped working after recent updates

What do those keys produce for "sudo libinput debug-events"?

For me it's exactly the same as with "xbindkeys --key". It's as if I am not pressing the buttons at all.

Re: [SOLVED] Media controls have stopped working after recent updates

Do they produce output in "sudo evtest"?
If not, possibly some wmi module gets in the way - does it still work w/ the LTS kernel?

I've tried 5.10 and 5.15 kernels. Bug reproduces anywhere.

"sudo evtest" registers the KEY_MUTE, KEY_VOLUMEDOWN and KEY_VOLUMEUP events for me.

I am also reproducing the issue on "5.15.28-1-lts".

Re: [SOLVED] Media controls have stopped working after recent updates

So it seems libinput drops the ball. Is it in the update list? From what version?

Re: [SOLVED] Media controls have stopped working after recent updates

You are absolutely right.

I downgraded to a previous version I found in /var/cache/pacman/pkg/ (libinput-1.19.3-2), rebooted, and the events are being registered and the keybinds are working.

The latest version (libinput-1.20.0-1) is the one where the bug can be reproduced.

So do we freeze the package in pacman.conf for now and raise an issue on their gitlab? https://gitlab.freedesktop.org/libinput … t/-/issues

Never mind. Apparently it has already been fixed.I guess the fix will arrive to Arch Linux with the next release.
