Hello,

I am trying to unlink the action triggered by my fn-F5 key, which is a toggle wlan action. I really don't know were this kind of action is defined, but I want to replace it by another one. It should happen either by unlinking that action or by overriding.

The key is catched by HAL:
showkey gives: Keycode 238
the driver defines: {KE_KEY, 0x0E, KEY_WLAN }, 0x0E being the scancode
and HAL knows it as: 'wlan'

Thank you in advance for your help and tips, I highly appreciate!

Best regards,
Quentin

Well, this does not help since it is about acpi events and I am using HAL events. Since the keycode is hardcoded in the driver, I probably won't be able to unlink it. One solution that comes across would be to override the keycode with a fdi file for HAL. Now, the question is how to find out the appropriate scancode, for example [1]:

<match key="system.hardware.vendor" prefix="LENOVO">
<match key="system.hardware.version" contains="3000">
<append key="input.keymap.data" type="strlist">e016:wifi</append> <!-- Fn+F5 Wireless -->
<append key="info.capabilities" type="strlist">input.keymap</append>
</match>
</match>

So, how do I find out the equivalent of e016:wifi on my box? The only information I have is:
showkey gives: Keycode 238
the driver[2] defines: {KE_KEY, 0x0E, KEY_WLAN }, 0x0E being the hex scancod

Are 0x0E and e016 both hex values, equivalent format? So can I use 0x0e:wifi?

Thanks for your support and kind regards,
Quentin

Any progress? I made some Fn+ keys do as wanted in the Desktop by mapping them to "Application Shortcuts" bu that is, of course, only effective after graphical login -- would be nice to do it at a lower level so they are effective in more states, including when displaying virtual terminals.

Ok, I made some progress: forget HAL, it is deprecated[1] and now udev takes over the keymaps. It works much better and is newer. You should read the following file to get familiar with it: /usr/share/doc/packages/udev/README.keymap.txt (on openSUSE, similar path on other distros)

The problem I now encounter is that I have two input devices on my laptop: /dev/input/event0 for my standard keyboard (AT) and /dev/input/event11 for the Lenovo ThinkPad specialkeys. Writing the config worked only for the first one, for now. If you can figure out how to edit the config for the second device, let me know!

The manual command to map the keys is the following:
With that I can override the keycode 'wlan' given by the driver with 'bluetooth' (you could map it to 'prog1' or similar to use it with the KDE shortcuts).

It works really fine, just have to figure out how to make this permanent.

Regards.

PS: you can find the scancodes with 'showkey -s' as root, but I looked it up in the driver sources [2]
