I though I might experiment a little. I installed xubuntu-desktop with the lightdm display manager. Didn't work either. Then I installed kubuntu-desktop with sddm display manger and the suddenly my touchpad started working. I then did a dpkg-reconfigure gdm3, rebooted and logged back into the "standard" gnome session. And now my touchpad is working with the Nvidia drivers installed and working. I have no clue why but, to resume, there are 2 workarounds: 1: use nouveau drivers instead of nvidia 2: install kubuntu-desktop (and log into ubuntu-desktop or whatever floats your boat).
This also indicates that it's "just" a config issue somewhere. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-libinput in Ubuntu. https://bugs.launchpad.net/bugs/1826597 Title: Synaptic touchpad not responding in ubuntu 19.04 when using nvidia drivers Status in xserver-xorg-input-libinput package in Ubuntu: New Bug description: On a Lenovo Thinkpad P50 with a Synaptics touchpad, the touchpad (or trackpoint), does not respond to any input after installing ubuntu 19.04. The same machine has been working fine with ubuntu 16.04 and 18.10. To be more correct it is still working in 16.04 hwe which I'm dual booting. If I uninstall the nvidia drivers (right now 418.56-0ubuntu1), and replace with noveau drivers it works just fine (by the way there seems to be no other issues with the nvidia driver as of yet). I have also the nvidia-driver-390 also suggested in the graphical software updates tool, to no avail. I will attach relevant logs. Please let me know if there is more I should supply. And thanks for all your hard (and brilliant) work.
