My touchpad is not working after the laptop (Lenovo Miix) wakes up from standby. I did some digging and found a lot of solutions that unload and re-load modules like hid_multitouch.
For me it is not working, after loading the module again, the touchpad still does not work. I noticed however that while the hid_multitouch modul is disabled, the touchpad works - but it acts funny: Its scrolls all screens with just one finger and higlights text in the console window.
As soon as I modproble the hid_multitouch module again, it stops working completely again.
My laptop is a Lenovo Miix and dmesg shows the device as SIPODEV Lenovo HID. I am using 21.10 with all updates installed, Kernel 5.13.0-22
