Title:
  Touchpad tap-event support broken since kernel 3.19.0-25

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Release: Ubuntu 15.04
  Hardware:  Logitech TK820 wireless keyboard with touchpad

  I've been using the said hardware with ubuntu in all releases since
  13.10 without problems. All touchpad features were working fine until
  I received in 15.04 the automatic update to kernel version 3.19.0-22.
  This kernel introduced a condition in which, at times, the system
  started randomly registering keyboard input when pointing with the
  touchpad.

  The original bug got apparently fixed in kernel version 3.19.0-25, but
  as a result this kernel version broke completely all tap-events for my
  touchpad. They are not registering at all. Pointing and scrolling
  work, so do the mechanical click-switches in the corners, but tapping
  or sweeping with one or more fingers does not get registered even
  though the settings were never touched. I now got kernel update to
  3.19.0-26, but the bug persists in this version, too.

  At the moment I had to revert back to kernel version 3.19.0-16 in
  order to be able to use my touchpad normally.
