disable touchpad

[Randy Dunlap]

Hi,

I want to disable the touchpad on my laptop.
The laptop is a Toshiba Portege and the toshiba_acpi driver
recognizes the laptop and reports that it has the following
capabilities:

[   24.392059] toshiba_acpi: Toshiba Laptop ACPI Extras version 0.24
[   24.472292] toshiba_acpi: Supported laptop features: hotkeys video-out fan touchpad accelerometer-axes usb-sleep-charge panel-power-on cooling-method


When I press Fn + F9 (touchpad on/off toggle), the keycode
is recognized AFAICT.  evtest reports:

Event: time 1584932366.360765, -------------- SYN_REPORT ------------
Event: time 1584932366.600689, type 4 (EV_MSC), code 4 (MSC_SCAN), value 143
Event: time 1584932366.600689, type 1 (EV_KEY), code 530 (KEY_TOUCHPAD_TOGGLE), value 1


Is there a way to configure xfce4 to recognize that keycode
and disable/enable the touchpad?

or do I have to handle this at the Xorg level?

thanks.
