show WMI magic Signals and activate hardware RF-kill button

show WMI magic Signals and activate hardware RF-kill button

[feldmaus]

Hi All,

my wlan Button, which should enable/disable my wlan card,
seems not to send signals which i can watch with <showkey>.

Larry Finger asked me:
"Is your radio on/off button one that generates a keycode, or does it
need the WMI magic to be detected?"

I need to get my wlan Button(hardware Rf-kill Button)
to work to still turn my wlan physically on.

What is WMI Magic and are there Linux commands to watch
was is going on?

Regards Markus

There is a protocol named WMI for Windows Management Interface. I
assume that it was invented by the folks in Redmond. In any case, it
is designed to handle events that have buttons that do not generate a
keycode. The module named hp-wmi is supposed to take care of the
things under Linux for HP and Compaq computers.

Did you generate this module? Is it loaded?

I dont use this module on my HP as my RFKILL switch generates a
keycode. Others may be able to help you with it.

By now, yes.
hp_wmi                  4632  0
rfkill                  9648  4 rfkill_input,hp_wmi,b43legacy
wmi                     6568  1 hp_wmi

But i still do not get any keycode with <showkey>.
Is there an other program than <showkey> ?

Where i can solve this problem with the wmi code ?

It will never generate a keycode. It uses some other means, which is
why I called it magic.

The module author is Matthew Garrett <mjg59@srcf.ucam.org>, whom I
have cc'd.
