Comment 83 for bug 1653456

When booting without USB mouse connected, my touchpad cursor is visible for 1 second before login screen appears. After inserting password, my touchpad cursor becomes again visible for few seconds...

By the way: "ELAN touchpad completely dead - possibly caused by Nvidia driver?"
https://devtalk.nvidia.com/default/topic/1016797/linux/elan-touchpad-completely-dead-possibly-caused-by-nvidia-driver-/
Developer conclusion: if ELAN touchpad is completely dead both with and without Nvidia driver, then it can be ELAN touchpad driver, kernel or bios problem and not Nvidia issue.

Next week I will perform a new clean installation without Windows and post here the results.
