Please attach your troubleshooting archives for each machinehas anyone managed to get the trackpad on the Lenovo Ideapad 330 15IKB 81DE to work, I've got 2 versions of the laptop (1 ELAN and 1 Synaptics) both only partially work. mouse moves but when I lift my finger off the pad the mouse keeps moving, and the trackpad is seen as a mouse in system preferences
The 'cursor keeps moving' problem is probably happening because you did not patch for GPIO interrupts (Or APIC, tho it's usually not possible).
As for multitouch - dedicated satellites (non-HID), like ELAN and Synaptics, require you to use interrupts before you can use them.
Those satellites are needed for older trackpad models that don't conform to the precision trackpad protocol.
