New to Arch/Linux. Running KDE Plasma with Wayland, keyboard has media keys on Fn+f-keys (just playback and volume control, 6 keys total), which don't work.
The the Fn+f-key keypresses are recognized by things like showkey, libinput debug-events and evtest, but not by Wayland (wev or KDE System settings).
I noticed that the keyboard is actually split into 5 different devices, each on their own /dev/input/event. The media inputs from the Fn key combinations are handled on a device separate from the rest of the keys: regular keys on /event6 named after the keyboard model, and the Fn media keys on /event5 with the same name + Consumer Control at the end.
Using fuser i found out that kwin_wayland is using event6 but not event5.
Switching to X11 made the media keys work right away and Xorg is returned by fuser on both events, but I'd like to continue using Wayland due to the HDR support.
Would appreciate any sort of help on fixing this on Wayland.
