Dalam file konfigurasi X tombol mouse dapat dipetakan menggunakan opsi ButtonMapping:

Section "InputClass"
    # ...
    Option "ButtonMapping" "1 9 3 4 5 6 7 8 2"
    # ...
EndSection

Mengubah urutan angka mengubah perilaku tombol mouse. Namun saya tidak dapat menemukan dokumentasi yang menjelaskan bagaimana perilaku tersebut ditetapkan. Dokumentasi kecil apa yang ada, saya bantu tulis.

Misalnya, jika pemetaan tombol ditulis demikian:

    Option "ButtonMapping" "a b c d e f g h i"

Kami akan mendokumentasikan posisi ini sebagai:

• a - Klik kiri
• b - Tengah
• c - Klik kanan
• d - Gulir ke depan
• e - Gulir mundur
• f - Maju
• g - Mundur
• h - Gulir horizontal
• i - Gulir vertikal

Pertanyaan saya kemudian: apa nilai-nilai posisi dari suatu melalui saya benar-benar mewakili dan bagaimana mereka dipetakan ke tombol mouse?

Running xmodmap -ppshow:

There are 10 pointer buttons defined.

Ini tidak berguna karena tidak mengandung informasi yang dapat digunakan manusia tentang atribut fisik mouse (yaitu, menunjukkan dua kolom angka tidak berguna tanpa nama tombol, seperti "tombol kiri"). Jadi sementara secara teknis ini mungkin menjawab pertanyaan "bagaimana mereka dipetakan", pertanyaan itu tetap tidak terjawab dalam arti praktis.

Saya pikir Anda harus melihatnya dengan cara ini:

                        1 2 3 4 5 6 7 8 9  <--position-- physical keys
Option "ButtonMapping" "1 9 3 4 5 6 7 8 2" <--function-- logical keys

• Posisi yang menunjukkan id kunci seperti yang dilaporkan oleh mouse (melalui driver). Jadi terserah pabrikan cara memesannya, namun sebagian besar tetap berpegang pada pesanan umum.

  Tikus masih menggunakan protokol lama seperti PS2, tidak memiliki cara menyimpan atau memberi tahu info tentang tombol yang tersedia dan fungsinya. Jadi X server tidak dapat memberi tahu Anda id dari setiap tombol fisik, hanya dengan mencoba mereka menggunakan alat seperti xevitu yang menunjukkan peristiwa X:

  xev -event mouse
  

  Atau evtestitu menunjukkan acara mentah:

  sudo evtest
  

• Kunci logisnya adalah yang sebenarnya dipetakan di tempat lain untuk fungsi tambahan. Pada level ini, X melihat mereka sebagai: button1, button2, button3, button4, ..., button24 dan tidak tahu fungsinya.

  7.  Configuration Examples

  This section shows some example InputDevice section for popular mice.
  All the examples assume that the mouse is connected to the PS/2 mouse
  port, and the OS supports the PS/2 mouse initialization.  It is also
  assumed that /dev/mouse is a link to the PS/2 mouse port.

  Logitech MouseMan+ has 4 buttons and a wheel. The following example
  makes the wheel movement available as the button 5 and 6.

  Section "InputDevice"
          Identifier      "MouseMan+"
          Driver          "mouse"
          Option          "Device"    "/dev/mouse"
          Option          "Protocol"  "MouseManPlusPS/2"
          Option          "Buttons"   "6"
          Option          "ZAxisMapping"      "5 6"
  EndSection

  You can change button number assignment using the xmodmap command
  AFTER you start the X server with the above configuration.  You may
  not like to use the wheel as the button 2 and rather want the side
  button (button 4) act like the button 2. You may also want to map the
  wheel movement to the button 4 and 5.  This can be done by the
  following command:

          xmodmap -e "pointer = 1 6 3 2 4 5"

  After this command is run, the correspondence between the buttons and
  button numbers will be as shown in the following table.

  Physical Buttons        Reported as:
  ------------------------------------
  1 Left Button             Button 1
  2 Wheel Button            Button 6
  3 Right Button            Button 3
  4 Side Button             Button 2
  5 Wheel Negative Move     Button 4
  6 Wheel Positive Move     Button 5


  Starting in the Xorg 6.9 release, you can also achieve this in your
  configuration file by adding this to the "InputDevice" section in
  xorg.conf:

          Option "ButtonMapping" "1 6 3 2 4 5"

  For the MS IntelliMouse Explorer which as a wheel and 5 buttons, you
  may have the following InputDevice section.

  Section "InputDevice"
          Identifier      "IntelliMouse Explorer"
          Driver          "mouse"
          Option          "Device"    "/dev/mouse"
          Option          "Protocol"  "ExplorerPS/2"
          Option          "Buttons"   "7"
          Option          "ZAxisMapping"      "6 7"
  EndSection

  The IntelliMouse Explorer has 5 buttons, thus, you should give "7" to
  the Buttons option if you want to map the wheel movement to buttons (6
  and 7).  With this configuration, the correspondence between the
  buttons and button numbers will be as follows:

  Physical Buttons        Reported as:
  ------------------------------------
  1 Left Button             Button 1
  2 Wheel Button            Button 2
  3 Right Button            Button 3
  4 Side Button 1           Button 4
  5 Side Button 2           Button 5
  6 Wheel Negative Move     Button 6
  7 Wheel Positive Move     Button 7

  You can change button number assignment using xmodmap AFTER you
  started the X server with the above configuration.

          xmodmap -e "pointer = 1 2 3 4 7 5 6"

  The above command will moves the side button 2 to the button 7 and
  make the wheel movement reported as the button 5 and 6. See the table
  below.

  Physical Buttons        Reported as:
  ------------------------------------
  1 Left Button             Button 1
  2 Wheel Button            Button 2
  3 Right Button            Button 3
  4 Side Button 1           Button 4
  5 Side Button 2           Button 7
  6 Wheel Negative Move     Button 5
  7 Wheel Positive Move     Button 6

  For the A4 Tech WinEasy mouse which has two wheels and 3 buttons, you
  may have the following InputDevice section.

  Section "InputDevice"
          Identifier      "WinEasy"
          Driver          "mouse"
          Option          "Device"    "/dev/mouse"
          Option          "Protocol"  "IMPS/2"
          Option          "Buttons"   "7"
          Option          "ZAxisMapping"      "4 5 6 7"
  EndSection

  The movement of the first wheel is mapped to the button 4 and 5. The
  second wheel's movement will be reported as the buttons 6 and 7.

  The Kensington Expert mouse is really a trackball. It has 4 buttons
  arranged in a rectangle around the ball.
