Bug #1900168 “touchpad motion stops responding sporadically in 2...” : Bugs : linux package : Ubuntu

Bug Description

a couple of minutes after boot, the touchpad stops responding (can't move the pointer, but the buttons are still responsive)

Machine: Thinkpad T460s
Kernel: 5.8.0-23-generic #24-Ubuntu
OS: Mate 20.10 beta

The Trackpoint (the nipple in the middle of the keyboard) and external mouse continue to function. The trackpoint however, moves much slower than usual.

EDIT:

Restarting lightdm.service fixes the problem temporarily. However, shortly after logging back in the touchpad stops responding again.

I had similar issue on my HP laptop with elantech trackpad, where trackpad would not be responsive immediately after login. The buttons would still work, external (USB) mouse would also work.

In my case the fix was to remove synaptics driver and let libinput handle trackpad.

sudo apt remove xserver-xorg-input-synaptics
sudo apt install xserver-xorg-input-libinput

I also created a symlink for 40-libinput.conf in /etc/X11/xorg.conf.d although it may not be needed (not present in UM 20.04).

sudo mkdir -p /etc/X11/xorg.conf.d
sudo ln -s /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/

A reboot was required for changes to take place properly.

I confirm that uninstalling the synaptics driver as per https://bugs.launchpad.net/ubuntu-mate/+bug/1900168/comments/32 fixes the issue. It is not necessary to add the symlinks.
