Bug Description

The installation scripts loads the correct drivers so the touch pad and pointer works during the install. However after the install neither work.

I've worked around it by using a wireless USB from Vilros for mouse input while logging in. Then issuing (found on https://askubuntu.com/questions/1143663):
 sudo 'echo -n "elantech">/sys/bus/serio/devices/serio1/protocol'

So it's a bug for me but one I can work around and should be fixed before 20.04 goes live.

Hi D.

Can you try uninstalling the nvidia-drivers from the "Additional Drivers" interface, just by choosing the nouveau drivers. Then reboot. Does the touchpad work now?

Then you might have a similar issue as I do on the P50:

Please use hybrid GPU mode in BIOS.
Or use psmouse.elantech_smbus=0 as workaround for now.
