Hello,

I recently used https://github.com/jloisel/t440p image to install Mojave to my T440p (without Nvidia). The clunky trackpad was replaced with a genuine Lenovo Synaptics T460 trackpad. Everything is fine except the 3 trackpad buttons do not respond.

Any suggestions are most welcome.

And one more with same problem and without solution. My trackpad buttons do not respond. I have tried the GPI patch in DSDT but without luck.

I use Dell Latitude 5400. Touchpad is partial working. I can use one finger to point and two fingers to zoom. But I cannot tap-to-click or use physical click buttons.

Mojave 10.14.6
