I found how to fix it. I found the solution here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1166442
and the laptop is lenovo g50-30 but i used the driver for lenovo g50-70 .
I used the attachment, and installed it with the terminal:
sudo dkms ldtarball psmouse-elantech-x551c-G50-70.tar.gz sudo dkms install -m psmouse -v elantech-x551c-G50-70
sudo rmmod psmouse sudo modprobe psmouse
It is working correct both right click and multi-touch.
