Comment 192 for bug 1166442

I have the same problem as arushi, my touchpad lacks multitouch. No dkms driver or kernel solved it. I also have a similar laptop regarding hardware (hp pavilion ab series) with an elantech touchpad, device is listed as ps/2 Elantech Touchpad and I have the same exact output for

dmesg | grep psmouse:
psmouse serio1: elantech: unknown hardware version, aborting...

I am on kernel 3.19 but I also tried other distros with the latest lts kernel (4.4) even in rolling releases, still no full support.
