Re: Fn Media keys not working

The Fn key is typically a proprietary HW feature that's not exposed as event to the OS at all, this isn't at all surprising.

As for the external keyboards media keys
1. What is that keyboard?
2. Do the keys show up in "evtest" or "libinput debug-events"?

Re: Fn Media keys not working

Sorry for hijacking this thread, I'm experiencing the same issue and might be able to provide some details to aid in troubleshooting.
Host: Acer Aspire E5-575G
DE: KDE Plasma (Wayland)
Panel/Dock: Latte
Weirdly enough, all other fn keys (brightness, volume, touchpad on/off) work just fine, it's only media controls that don't work.
The key events are detected by libinput debug-events and the play/pause button is bound to play/pause in KDE's keybinds settings (which is the default)
I read this, and made sure that I had a media control widget in my panel.
The issue was "fixed" by adding a media control widget to my desktop. So for some reason, having a media control widget in the system tray is not enough.
I should note that I use a fork of KDE's media control widget instead of the default one.
I'll do some more digging and report back if find a better fix.

Re: Fn Media keys not working

Please remove the oversized image of your keyboard -there's a 250²px² limit and it's overexposed so one can't see the Fx keys anyway.

I assume this is your keyboard?

Run "sudo libinput debug-events" and press F4 and Fn+F4 and post the output.
