Laptop model: xiaomi mi notebook air 12.5 m3-7y30
Touchpad: Synaptics
Ubuntu version: Ubuntu 4.15.0-88.88-generic 4.15.18
Description: Ubuntu 18.04.4 LTS
Release: 18.04
Problem appeared ~2 months ago
Touchpad worked fine for 2 years, now suddenly not anymore. No sign of
activity. Touchpad and mouse usage does not activate anything on the
computer screen. I can't find help on how to restore the previous state,
how to get the touchpad working again.
when filing cmd command xinput list, synaptics touchpad and/or mouse are
NOT displayed. command "cat /proc/bus/input/devices" also does not show
a touchpad device.
