Interesting. I am running the latest Kernel and I don't have this bug,  but another one.  My touchpad works fine, as do left and right mouse buttons. However, whenever I keep using the touchpad instead of an external mouse consistently: ubuntu freezes within a period of 2 to 25 minutes. I kept thinking that it must be for another reason that this is happening, but it definitely ONLY happens (the freezing) if I use no external Mouse for my ASUS X550-C. 
Anyone else has this?

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:
