Public bug reported:
Laptop is new, I bought it yesterday. I'm dual-booting Windows 10 and
Ubuntu 20.04. Touchpad works on Windows.
The touchpad does not show up in xinput --list and in the devices
(included in the attachment). Its manufacturer is Elantech, at least I
suppose it is, based on an output from acpidump which has shown:
27AD0: 54 59 01 70 0D 45 4C 41 4E 30 36 33 33 00 5F 48 TY.p.ELAN0633._H
on one line. If it is in fact my touchpad and its ID is 0633, then it is
not included in elan_i2c_core.c file in my ubuntu kernel source (IDs end
at 0632). I tried to modify it myself and compile a new, custom kernel,
but I am quite new to linux so I failed.
