Multi Touch e Display

Question

Eu tenho configuração de monitor duplo, ambos são touch screen de tamanho diferente e de modelo diferente. Eu obtenho o seguinte resultado quando executo o comando:

 user@user-hpEnvy:~$ xrandr
    Screen 0: minimum 8 x 8, current 3840 x 1080, maximum 32767 x 32767

       1024x768       60.0  
       800x600        60.3  
       720x576        50.0  
       720x480        60.0     59.9  
       640x480        60.0     59.9  
       720x400        70.1  
    VIRTUAL1 disconnected (normal left inverted right x axis y axis)

E o resultado do próximo comando é como:

   user@user-hpEnvy:~$ xinput
    ⎡ Virtual core pointer                      id=2    [master pointer  (3)]

        ↳ Video Bus                                 id=8    [slave  keyboard (3)]
        ↳ Power Button                              id=9    [slave  keyboard (3)]
        ↳ HP Truevision HD                          id=12   [slave  keyboard (3)]
        ↳ AT Translated Set 2 keyboard              id=14   [slave  keyboard (3)]

Aqui tenho dois monitores: eDP1 e HDMI1 Além disso, com dois dispositivos de toque: ELAN20E7: 00 04F3: 20E7 e SynPS / 2 Synaptics TouchPad

Agora, a pergunta é: como identificar qual tela sensível ao toque pertence a qual exibição? Quero identificar esse mapeamento para outras operações.

OR

É possível inscrever todos os dispositivos USB conectados de Board to Monitor?
