Multimedia keyboard and extra keys

Hi,

Question 1:
I am new to Linux and looking for a way to control and change volume with extra keys on my Multimedia keyboard.
Volume in- and decrease was no problem with aumix, but with the mute funktion I have some big problems. Right now I am trying to build a script to restore the volume after disabling mute.

In this forum there is a thread, where other users reported that KMix had taken control of volume keys.
Can anybody explain to me. how I can take advantage of this "feature"?
Seems to me that this is what I am looking for... :-)


Question 2:
X11 has only 35 F-keys. How can I increase this number? Or is it possible to declare new key names?

RE: Multimedia keyboard and extra keys

1. Multimedia keys are threathed by X11 as Function Keys. In KDE, it is possible to execute a command when a key of key-combination is pressed. So you can execute a choosen command when you press a multimedia key.

AFAIK, there is a mute-function in KMix. So you can toggle that function if you press a function key. If KMix doesn't this self, you can make a script that toggles this button (using DCOP).

2. {number of normal buttons on a keybord} - {number of functions keys} + 35 (number of addressable function keys) = 105 - 12 + 35 = 128, and that is a power of 2. So, maybe it is a limitation of (serial) keyboards.

Until now I had my MM keys as Function keys defined in de-latin1-nodeadkeys2.map.
Maybe not the best way but the only one for me to have them linked as Function keys to commands with KHotkey.

There seems to be another way to let X load them as Function keys from ~. (Manually I can do it with xmodmap ~/.Xmodmap).
What is the name of the file which is loaded on any KDE startup to map the keys?


Mart_k, you wrote:

I checked some books and tried to find help in the internet, but I didn't stumble over informations to KMIx nor can I write such a script (I want to change that).
Where can I find such informations?

Since KDE 3.3, everything in ~/.kde/env is executed when you startup KDE. So that is a good place to run xmodmap. (You may have to make that subdirectory)

I made such a function before, but that was on another computer, so I coundn't paste the function. The command is:

Source code

 
1

dcop kmix Mixer0 setMute 0 $( [ "$(dcop kmix Mixer0 mute 0)" = "true" ] && echo "false" || echo "true" )
KMix must be running, otherwise it does nothing.

Hello again,

when I clicked on the english manual of KMix I found the desired hints for dcop commands. 8o
The german help doesn't have the translation by now.

Yesterday I managed to implement the MM keys in KDE as script in ~/.kde/Autostart.
:O I first tried to create ~/.xinitrc to do this, I forget the first script line #'! /bin/bash or so and as a result I couldn't log in any more as user...

Mute:
KMix has (in KDE 3.3) a hotkey function for mute, as I found out, ...
but KMix don't want run automaticly. :(
Thanks for the command nethertheless.
