Vamilo keyboard disfunction in ArchLinux

Pre

After having used Arch Linux for a while, one day I want to use F12​ in browser, but something went strange: whatever I pressed, F12​ or Fn+F12​, they all only adjust my pc volumn.

Then

After searching on Archwiki, I found that may be my kernel is defaulted to use the media keys.

But it's still ware, why my other keyboards work normally, but the Vamilo has this problem.

Without asking more, I put the solution into my pc:

# echo 0 | tee /sys/module/hid_apple/parameters/fnmode

then restart, everything back to normal.
