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 Ubuntu-X, 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-libinput/+bug/1826597/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
