Public bug reported: 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.
