Ok, and what about KEY_KBDILLUMTOGGLE when bios also handle
keyboard backlight level? Should be this key filtered too?
IME, heck yes.
If you ever make the mistake of sending to userspace something
the BIOS/kernel already reacted to, they will find a way to
loop it back to you and cause all sort of issues.
Ok, I think same. In KDE4 I see some loop/noop operation when new
dell keyboard backlight driver is used. Key KEY_KBDILLUMTOGGLE
cause that BIOS change brightness and also KDE4 see it and change
it too...
Similar problem there is with KEY_WLAN and NetworkManager.
Gabriele, can you create patch which disable both KEY_WLAN and
KEY_KBDILLUMTOGGLE in dell-wmi.c driver?
