I'm using 20.04 Ubuntu with Gnome desktop and have the same issue. As a
fix I used code mentioned above Eg "modprobe psmouse" as the solution.
I placed the following code in a file called "touchpad"
#!/bin/sh
$sudo modprobe -r psmouse && $sudo modprobe psmouse
To do that I used "sudo gedit" and navigated to the directory and put the text
in.
I then ran the below command in the terminal to make it executable
chmod +x /lib/systemd/system-sleep/touchpad
To my understanding (which is limited) anything in that directory runs
when the computer wakes up so the two finger option starts again
automatically. The "touchpad idea came by varying the code on the below
site with the solution mentioned above.

after-suspend
It appears to work reliably so far, and while it is not a true fix to
the bug, it might further assist in the meantime.. Cheers M.
