Touchpad disabled at login screen

[retesta]

After successfully installing and configuring mtrack on my LG Gram 2018, I am unable to use the touchpad on the login screen. It won't register clicks nor movement. Plugging in a mouse works on the login screen.

After logging in everything works properly as it should. The issue only happens to the touchpad at the login screen.

Running Ubuntu 18.04 LTS
