touchpad - How to switch from libinput to synaptics in Ubuntu 18.04



There is a problem with my laptop — jumping cursor. I think the hardware is the source of the problem. Maybe toucpad is just very inaccurate when getting finger coordinates and touching events.



On Ubuntu 14.04 I just set vertical and horizontal hysteresis and high and low finger pressure to make touchpad feel smooth and nice. When I installed 18.04 I found that I can't adjust my touchpad any more (except a few options that are not too helpful in my case).




So, can anybody of you, guys, help me with getting back that beautiful synaptics driver?



I had the same problem and basically solved it by following Ryko's advice.



sudo apt install xserver-xorg-input-synaptics


... did the trick. I didn't uninstall libinput like Pilot6 said and libinput is still happily handling my keyboard, etc.
