--- Comment #4 from Jean-Paul Lambrechts <jlambrec at comcast.net> ---
The kernel with gentoo (gnome3-wayland) is 4.9.76-gentoo-r1
The kernel with the system-rescue-cd is 4.14.20-std521-amd64
The kernel with gentoo is the one that is recommended during the installation
by the Gentoo team.

######## Looks like the touchpad is at event 7.

Do you think the newer kernel on the rescue disk is the reason why the touchpad
is found?
