In cammed line, run:
sudo modprobe -r psmouse
It should work fine for now but only for current session, it may not work after restarting your laptop, so to add permanent fix, do:sudo vim /etc/modprobe.d/psmouse.conf
And add following, then save and exit.
options psmouse proto=imps
I used vim, you can use your favourite text editor such as gedit, vi etc. I hope this helps someone and save their time. Read more on modprobe.
