[Andrea Pacelli <ap65536@xxxxxxxxx>]

Public bug reported:

Hi, my Acer E3-111 stopped recognizing the touchpad.  External mouse works; the machine seems not to recognize the hardware.  Even the system settings only shows me mouse settings.  Attaching dmesg and devices.
The problem started about a week ago after installing an update and rebooting.
Thanks!
Andrea
