Hi,
I have a Terios P4 wireless gamepad.
I have already paired it to the pc via a usbbluetooth dongle.
I just need to disable the touchpad of the gamepad upon connecting it via bluetooth, so it doesn't interfere ingame. So I wrote a script , which is as simple as :

#!/bin/bash
#
xinput set-prop 16 "Device Enabled" 0

The problem is that, with my limited bluetooth experience, the script is not getting triggered via a udev rule.
My udev rule is :

ACTION=="add", SUBSYSTEMS=="bluetooth", ATTRS{DEVNAME}=="/dev/hidraw4", RUN+="/home/pingu/scripts/terios_disable_touchpad.sh"

The script runs correctly if run seperately/independently.

Where am I going wrong with this ? Any pointers/help is appreciated.

Thanks.

That will require extensive troubleshooting & testing: finding the right triggers etc.
Check out this article.

I managed to resolve this matter via settings in the xfce menu (duh).
After connecting my gamepad , start/applications menu -> settings -> mouse and touchpad , dropdown box in devices tab will show touchpad , disable it. (silly me)

But I hope to resolve it through a udev rule someday.

Thanks.

Running xinput may take too long for udev - you might have to offload it to a systemd unit. Which of course you will also have to write. Settings would be my go-to while it works.

Does udev run scripts as root by default ?
I ran the script as root but it showed "cannot connect to X display" or something.
So I added a "export DISPLAY=:0.0" to the very beginning of the script and it ran.

I tried a hell lot of variations of udev rules including ATTRS{DEVPATH}, ATTRS{DEVNAME} etc and none of them worked.
Playing games, the KISS philosophy simply wins by disabling it using gui settings.

Sorry, discard it.

The article I linked addresses all this.
