Using a Lenovo T450s, the touchpad (Synaptics) and the TrackPoint are
completely nonfunctional on the Leap 15.0 installation ISOs, both the full DVD
and the Network install. Mouse does not move and mouse cicks are not registered
at all. Xorg has no mention of a mouse input device in its log.

Both are working fine on the GNOME LiveCD.

I believe this is because the rmi_smbus and rmi_core modules are missing. I
could not load them manually, they do not seem to exist.


The following input is completely absent when running from the installation
media but is found on a working system and the LiveCD:
