'Touchpad' suddenly stopped working without any update on 'Lenovo Thinkbook IML 15'

Asked by Waseem Abbas

My touchpad has suddenly stopped working on 'Lenovo Thinkbook IML 15'. Its not a hardware issue because touchpad is working on my Windows OS. I didn't install any update when this issue appeared.
Touchpad device is also not showing up in `xinput --list` and `/proc/bus/input/devices`.
