How to turn off DS4 Touchpad as mouse?

[Dekthor]

The PlayStation 4 controller has a touchpad on it. When hooked up directly to the PC (Win7) for Steam it is used as what the user sets it as through the Steam Controller configurator. In my case I used it as 2 buttons.

Anyhow the RetroPie uses that pad at a mouse touchpad. When I use Steam Link and remote into my PC it imposes it's mouse pad config over my steam config. I press my touch button and it both creates a mouse button click and my desired function... Which isn't desirable lol. I don't need a mouse in retropie so I hope to disable it while still letting steam utilize the controller to its fullest.

From what I've read from Linux forums the fix usually is to go into the GUI and turn the touchpad off. But I don't have a desktop environment setup and I can't find it in any of the other settings. So I imagine it's going to be a bit of command line kung fu.

This is an older controller and works on a fresh unmodified retropie install.

You may be able to disable it with an udev rule. Create a file ( with sudo nano /etc/udev/rules.d/85-disable-ds4-touchpad.rules) with the following content and then restart your system to see if the touchpad still appears.

SUBSYSTEM=="input", ATTRS{name}=="*Controller Touchpad", RUN+="/bin/rm %E{DEVNAME}"
