None of them were. I installed them all with the Muon Package mgr in Lubuntu. There were two otehr synaptics pkgs that ended in 28.04 and I did not install them -- just three as you stipulated above. I will reboot.Make sure the following packages are installed = (xserver-xorg-input-all) = (xserver-xorg-input-synaptics) = (xserver-xorg-input-kbd)
enabling or disabling through xinput is temporary and will go away after reboot
To enable the keyboard tryCode:xinput set-prop "AT Translated Set 2 keyboard" "Device Enabled" 1
