I also have this issue. The pointer becomes frozen about 1-2 sec, at
this time, it can move, but no actions work. My laptop: Xiaomi Mi
Notebook Pro rev.2
any touch on the touchpad generates a bunch of errors:
i2c_hid i2c-ETD2303:00: i2c_hid_get_input: incomplete report (14/65535)
This issue is relevant for kernel version 4.20.13. OS: Arch linux.
