Multimedia play/pause, skip forward, skip back keys not working

[Christopher Snowhill]

Ever since I recently installed Kubuntu 18.10, using debootstrap and `apt install kubuntu-desktop` method, upon reaching a desktop, the multimedia keys on my Apple Wireless Keyboard do not have any effect on anything.

The F3/Exposé key correctly triggers the window display mode, F10/Mute toggles the sound mute, F11 and F12 correctly adjust the master volume level.

F7, F8, and F9 have no multimedia control effect. Running `sudo showkey -k` shows keycodes 165, 164, and 163 for the three keys, respectively. `xev` does not report any media key activity for any of those three keys, just focus in/out events on key down or up.

I expected the multimedia play/pause, forward, and backward keys to control the current application appearing in the KDE/Plasma desktop integration for sound control.

Currently, they have no control over any applications, whatsoever.

I have determined this to be a lack of input overrides in the udev hwdb.d 60-keyboard.hwdb definition. For now, I have declared the following in my /etc/udev/hwdb.d/90-apple-keyboard.hwdb, which I'll attach. It may or may not be accurate for all Apple keyboards.

Disregard that, I am wrong. The bug appears to be with the plasma-desktop multimedia keys integration, which appears to be broken now.

This bug is very old, if it is still an issue please update the bug with information from a supported release.
