Thinkpad touchpad mouse cursor laggy/choppy | Ubuntu 18.04

Question

I am new to ubuntu so please keep that in mind.

I installed ubuntu 18.04 LTS on my Thinkpad L540. Most often my mouse cursor, if I use my touchpad, is laggy/choppy in a visual way. This does not happen if I use an external mouse (bluetooth). Everything else is working fine (fluid/without lags). After some reboots, it sometimes works.

I take the notebook with me and I often cant use a bluetooth mouse, so I am stuck with rebooting my device as many times as it takes, to get it working.

Did not happen on Windows 10. That is my first try installing Linux on this notebook.

I presume that my touchpad device is a SynPS/2 Synaptics TouchPad (Terminal: xinput).

Any advice on what I can do or check to get rid of this problem?

Solution 1

see my answer here:

I can confirm a similar issue with my touchpad on HP ProBook 450 G6 with Ubuntu 18.04, it was very laggy after suspend.

What worked for me: create /lib/systemd/system-sleep/touchpad:

#!/bin/sh

case $1 in
  post)
    /sbin/rmmod i2c_hid && /sbin/modprobe i2c_hid 
  ;;
esac

make file executable chmod +x /lib/systemd/system-sleep/touchpad and test (suspend computer and wake-up again)

Solution 2

I had this (or a similar) problem with a thinkpad 470. The mouse pointer was suddenly choppy after a reboot. Rebooting did not help.

The problem finally went away after I sent it to sleep and woke it up again. (sudo systemctl suspend)

Solution 3

I have same problem on my Thinkpad T460s with Ubuntu 18.04 (Ubuntu 16.04 and Windows 10 have no problem). I tried the solution here and after reboot, the problem was solved.

sudo apt install xserver-xorg-input-synaptics-hwe-18.04

Can you clarify if the lagginess is always present no matter what speed you move the pointer, or only if you are moving the pointer slowly?

@Michael I installed Manjaro and dont suffer from this issue anymore. But the problem was consisten (didnt matter if i moved slow or fast). Thanks for asking tho :D

I have a much worse version of this problem, even after installing xserver-xorg-input-synaptics: the mouse cursor moves/clicks only about 5% of the time I use the Touchpad. I've left comment #28 on that bug.

I am using 18.10 and this problem still there

I have an HP Probook 440 G6, with Ubuntu 18.04, and this worked for me. Thanks!

I also had the problem on a T470 and disabling the track point didn't help
