Cannot use twofinger on lenovo z5070 touchpad ubuntu 14.04.

I also tried

twofinger scroll on lenovo g50

ALPS touchpad detected as PS/2, corrected with psmouse-dkms-alpsv7 but reset after reboot

Ubuntu 14.04 - Lenovo Ultrabook Touchpad Drag not working

pointing devices

when I use command synclent

It return "Couldn't find synaptics properties. No synaptics driver loaded? "

I also tried to reinstall xserver-xorg-input-synaptics

sudo apt-get purge xserver-xorg-input-synaptics sudo apt-get install xserver-xorg-input-synaptics


My solution.

cat /proc/bus/input/devices

if you found something like this

N: Name="ETPS/2 Elantech Touchpad" then do the next procedure

apt-get install dkms

if cannot access dkms. try

export PATH=$PATH:/usr/local/sbin

Step 1: Download the following dkms package


Step 2: Run the following commands in the download directory (or adjust the paths accordingly):

sudo dkms ldtarball psmouse-elantech-x551c.tar.gz

sudo dkms install -m psmouse -v elantech-x551c

sudo rmmod psmouse

sudo modprobe psmouse
