touchpad and trackpoint cursor jumpy and inaccurate Ubuntu 20.04 Thinkpadx 240
My problems with jumpy and inaccurate cursor started after upgrading x to hwe on Ubuntu 18.04.02 (4.18.0-20-generic) thinkpad x240 libinput 1.10.4-1 input-libinput-hwe 0.28.1-1
I assume that my earlier version was 0.27.1-1. Before updating touchpad was working smoothly.
Things changed a little when I did a fresh install of Ubuntu 20.04. input-libinput 0.29.0-1
Now also trackpoint is jumpy and inaccurate and Touchpad sometimes stops working after suspend. On rare occasions everything is working smoothly.
I manage to fix touchpad not working after suspend by adding "psmouse.synaptics_intertouch=0" to grub. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1788928 After that, cursor is always jumpy – there are no more situations when everything is working fine.
