Xserver 未接收触摸板事件

Ubuntu 20.04，内核 5.15.0-43-generic。xinput 检测到触摸板：

$ sudo xinput list
⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Logitech USB Optical Mouse                id=17   [slave  pointer  (2)]
⎜   ↳ Apple Inc. Magic Trackpad 2               id=9    [slave  pointer  (2)]
⎜   ↳ Apple Inc. Magic Trackpad 2               id=10   [slave  pointer  (2)]
