hi folks...
i assume, some of you have already encountered the problem with
not-working extra-keys on your laptop.
the numerous tools available work by assigning unassigned
scancodes to keycodes (to characters/starting programs), as it seems to
me. this may be different for tools for specific laptops (like tpctl,
i8kutils), which i do not have access to.
the problem arises, when there is no scancode at all for a specific key,
when the keyboard controller does not send any code to the driver.
you can test this with "showkey -s". and i have seen a couple of laptops
which do not generate a scancode when hitting an extra key.
it seems that the keyboard driver has to send a magic byte string to the
controller for that to work.
so does anyone of you have any experience in this regard? anyone who
actually did or tried this?
tia,
sebastian
