Comment 14 for bug 1798363

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.
