I was following this instructions with Ubuntu 14.04. https://github.com/he1per/psmouse-dkms-alpsv7 and psmouse serio1: alps: Unknown ALPS touchpad in a Lenovo Ideapad Flex 15

And after many tries I received the following error message:

root@alisson-Lenovo-Ideapad-Flex14:/tmp/psmouse-dkms-alpsv7# ./install.sh ────── Building with dkms ───────

Error! DKMS tree already contains: psmouse-dkms-alpsv7-1.0 You cannot add the same module/version combo more than once. Module psmouse-dkms-alpsv7/1.0 already built for kernel 3.13.0-24-generic/4

than, searching for "psmouse.ko":

alisson@alisson-Lenovo-Ideapad-Flex14:~$ locate psmouse.ko /lib/modules/3.13.0-24-generic/kernel/drivers/input/mouse/psmouse.ko /lib/modules/3.13.0-24-generic/updates/dkms/psmouse.ko /var/lib/dkms/psmouse-dkms-alpsv7/1.0/3.13.0-24-generic/x86_64/module/psmouse.ko /var/lib/dkms/psmouse-dkms-alpsv7/1.0/build/src/.psmouse.ko.cmd /var/lib/dkms/psmouse-dkms-alpsv7/1.0/build/src/psmouse.ko alisson@alisson-Lenovo-Ideapad-Flex14:~$

What should I do?

I had the same issue with my Lenovo Ideapad Z510. Touchpad was recognized as PS/2 Mouse. No configuration available for scrolling or disabling while typing. Scrolling did not work.

I installed Kernel 3.14.1 then everything worked fine after reboot.

Yesterday I did a normal update asked by ubuntu and today to my surprise the two fingers option has begun to function!
