- Lenovo Thinkpad T480
its a precision touchpad so its connected on SMBUS and PS2. This can be verified in with lscpi in linux. It *should* be possible to get the gestures working with vooodooi2c if it can be seen via SMBUS, similar to how this kext sees the elan trackpad- https://github.com/gokula/ELANSMBusIts weird...
I just put voodooi2c&voodooi2chid in my /library/extensions , and the touchscreen works like a charm...
About the touchpad , I guess x1 extreme use synaptics ps/2 touchpad as well , so it will not work with voodooi2c. If you use acidanthera or syscl version of voodoops2 controller , you can have one~three finger gesture.
Oh... Forget to mention that syscl or acidanthera version with voodoops2controller might conflict with voodooi2c , so if you want to use touchscreen gesture , use voodooi2c&voodooi2chid + rehabman's voodoops2controller.
This is the screenshot of my ioreg(HS10 is pen and multitouch sensor) , and also attached my ioreg , hope it helps
