Hello everyone. I'm not using KDE, but my mum and a friend do.

Using xev identified all the media keys we needed to figure. Then wrote them to ~/.Xmodmap, added
script to ~/.kde/Autostart/ so KDE works fine with volume keys! I was really surprised that when I pressed the volume Up key, it showed up a volume meeter changing.

That was great. But that was also a fail. Because I'm not able to figure out where exactly does KDE keeps what it execs. To fix it. Because pressing for example the 'mute' key just turns off the wrong ALSA control. Actually our soundcard does not have a Master control, so it turns off nothing, just shows the crossed dynamic icon in the tray.

Other keys are 'play/pause', 'stop', 'next song' and so on. Just as usual. They do not generate(luckily) ACPI signals, just standard X events. So how to configure them all?

Have to admit, I am a complete GUI fool, using only fluxbox and Xfce(much more rarely) and CLI.

I don't know the answer to your question, but you might want to take a look at an application called keytouch:

I've used it in the past to get special keys working. It's a lot easier than trying to do it by hand.

For KDE, you can use its built-in tools to map keyboard shortcuts to actions. If you want to use another WM/DE, you could use xbindkeys to do the same. See here for more information: http://dev-loki.blogspot.com/2006/04...h-xmodmap.html

My keyboard volume keys were correctly mapped, and pressing them showed a volume bar that increased or decreased, and mute muted/unmuted on the screen, but no actions were physically taken. Since I use KMix, I used KDE's Input Actions to send dcop messages to kmix to increase, decrease or mute/unmute. It works beautifully. This whole process is explained in the provided link. It should be noted that the "Master Channel" is incorrectly set for my sound card, so I had to pass a non-zero argument to kmix's dcop interface to increase/decrease/mute/unmute the proper channel. If you don't use kmix, or you use a different WM/DE entirely, you could always send arguments to amixer or some such thing instead.
