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.

Title:
touchpad motion stops responding sporadically in 20.10 mate beta
Status in Ubuntu MATE:
New
Status in linux package in Ubuntu:
Confirmed
Status in xserver-xorg-input-synaptics package in Ubuntu:
Confirmed
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.
