A tecla é constantemente pressionada tecla fantasma do teclado

Question

Eu tenho uma tecla que é constantemente pressionada, até mesmo desconectando o teclado e alterando-o para outro.

OS: Linux Mint 18.3

$ xev | grep 'keycode'
state 0x10, keycode 221 (keysym 0x0, NoSymbol), same_screen YES,
state 0x10, keycode 221 (keysym 0x0, NoSymbol), same_screen YES,
state 0x10, keycode 221 (keysym 0x0, NoSymbol), same_screen YES,
state 0x10, keycode 221 (keysym 0x0, NoSymbol), same_screen YES,
state 0x10, keycode 221 (keysym 0x0, NoSymbol), same_screen YES,
state 0x110, keycode 221 (keysym 0x0, NoSymbol), same_screen YES,
state 0x110, keycode 221 (keysym 0x0, NoSymbol), same_screen YES,

já tente:

$ xmodmap -e 'keycode 221 = '
# And
$ xmodmap -e 'keycode 221 = NoSymbol'

Quando pressiono várias vezes a tecla ' , obtenho isto:

''ῢ''ῢ''ῢῢῢ''ῢ''

Os Kernels Linux que eu uso são:

4.13.0.32
4.14.0

e os dispositivos:

Alguma sugestão sobre como corrigir esse erro?

Found that /dev/input/event3: PEAQ WMI hotkeys was causing the error.
