how to make system recognize all my Fn key bindings

In my system, only these key bindings with Fn could work. They are Fn, F3, F4, F6, F7, F11, even in terminal. They work perfectly.
but xev, it can recognize a little more, such as Fn+F1, F10, F12. How could I make those keys work, not only in desktop, but also in terminal? For example, pressing Fn+F1 will make the system locked in Windows.
Also there are other key binding that the system doesn't know. They are Fn+F8, F9 which works for toggle the wifi and touchpad. How could I make system know these?

Thanks.

And, they don't return me any information when I press only Fn.

You can use 'showkey' to see if the system (not just Xorg) is mapping the keys. I think there is also a message in dmesg for using setkeycodes to map keys that are unmapped. Once they are mapped systemwide, you can use xmodmap to configure what they do in Xorg.

You might also check the kernel in Device Drivers->X86 Platform Specific Device Drivers for support for your system.

There's also Toshiba Laptop Extras (ACPI_TOSHIBA) in the same menu. If you search for it you will see the list of DEPENDS (kind of a long list.)

On the other hand, I don't know if this will help. Did you try

1) press the key combination
2) check 'dmesg tail'
3) does it have an error about the key press?

Some Fn key may not generate keystroke, but ACPI events. Use acpi_listen to see what they do. And compile right additional ACPI driver for your laptop
(TOSHIBA_LAPTOP_EXTRAS in your case) - it is almost certainly needed for proper ACPI mapptings !

Once ACPI codes are confirmed to be generated, your desktop environment will probably pick them up, or you can run acpid and write your own small scripts to handle these events
