Elantech Touchpad Fix

Temporary fix:

sudo sh -c 'echo -n "elantech"> /sys/bus/serio/devices/serio1/protocol'

Permanent fix:

Edit /etc/default/grub

vim /etc/default/grub

Edit GRUB_CMDLINE_LINUX_DEFAULT with psmouse.elantech_smbus=0

GRUB_CMDLINE_LINUX_DEFAULT=quiet psmouse.elantech_smbus=0

You may have some other arguments in there, like splash.

Update grub to take effect

update-grub

Reboot
