So I have and Asus R558UF notebook with an Elantech Touchpad. After installing Ubuntu 16.04, the touchpad worked once but after restarting, it failed to work and has not been working ever since.
This is output of
↳ Elan Touchpad id=12 [slave pointer (2)]
In Mouse and Touchpad settings, the touchpad is enabled. What should I do to fix this?
