[Bug 1387428] Re: Elantech Touchpad input device freezes in x

 

So the quick fix would be:
1.) Run following command from terminal:
echo "options psmouse rate=60 resync_time=10" | sudo tee /etc/modprobe.d/psmouse.conf >/dev/null

2.) Reboot the system or reload psmouse module from terminal with following commands:
sudo modprobe -r psmouse && sudo modprobe psmouse

One of the psmouse attributes may be unnecessary
