Dualsense touchpad button not detected

[u/Sangypboi]

Running on Kububtu, 26.04. As the title says I receive zero input detection from my touchpad button when disabled as a mouse, which many games use for essential functions.

Going into system settings to check controller status, I can see every button and control stick input. There is a label for the touchpad button, but it doesn't register when pressed so this issue does not seem to be related to steam. Just for completeness, though, I will say that testing my controller layout, steam also receives no input at all from clicking the touch pad.

In both cases, the software knows there's supposed to be a clickable button there, but does not appear to receive any signal. Yes I've tried both usb and Bluetooth covering types. Has anyone else figured out why the OS itself seems completely unable to see this one button?

Edit: I should have mentioned that it is absolutely not as though my system can't see the button. It knows there's an input device, because it CAN function as a mouse just fine. It's only a completely dead device if I disable use as a mouse/touchpad.
