Hi,

The same problem here with my ASUS X550CA. Touchpad does not work AT ALL
on any recent Ubuntu version (and Mint, Debian live, Manjaro and some
other distros as well).

Cursor jumps and the system freezes for a few minutes.

However I have just tested PClinuxOS in live mode (KDE and Mate versions, burned on DVD-RW, as Unetbootin did not work on this distro) and the touchpad works fine for movements and clicks! (the only thing is the lack of scrolling -vertical or two-finger scrolling). 
PClinuxOS uses kernel: 3.18.1-pclos1 
There's no way of changing settings for the touchpad, as only the USB mouse gets recognised in the Control Centre...
Anyway, hope this helps some people who want the touchpad to work somehow on a GNU/Linux distro...Thanks

Title:
  [Asus X550CA] Touchpad not working in ubuntu 14.04

Status in linux package in Ubuntu:
  Triaged

Bug description:
  The touchpad functions properly on my X550CA laptop under Windows 8 64bit. It doesn't work properly with Ubuntu 14.04 64-bit. The cursor doesn't move at all or just barely from time to time. Right or left-click doesn't work. The touchpad is not properly recognized by the OS. It seems to recognized it as “PS/2 Logitech Wheel Mouse”, as shown by:
