Title:
  Touchpad doesn't work unless middle-click is constantly pressed (on an
  Elantech touchpad, in a Fujitsu H730)

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Issue:
  Using a fresh install of Ubuntu 14.10, I discovered that the touchpad did not work.

  Steps to reproduce:
  Install Ubuntu 14.10 on a Fujitsu H730 and attempt to use the touchpad.

  Further description:
  However, I stumbled across bug #1300427, where there was mention of both a workaround and a fix in a newer kernel.
  I have been able to use the workaround -- which is basically limiting the protocol of the psmouse module, such that I remove and load psmouse with proto=exps.

  After this, a bit further in time, I accidentally managed to click with the touchpad. It appears that the touchpad strangely enough works quite well as long as I hold down the middle click button. While holding it down, the touchpad seems to work rather well - including multitouch features.
  The joy is short, as it registeres no input while depressed.

  Things tested:
  Due to the comments in bug #1300427 I've tested the mainline kernel version 3.17-rc5-utopic, and the only impact I recall was how the right-click button now also worked while pressing middle-click on the touchpad.
