Title:
  [Lenovo IdeaPad Flex 14] ALPS Touchpad incorrectly detected as PS/2
  mouse

Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  Laptop Model: Lenovo IdeaPad Flex 14
  Model Name: 20308

  Touchpad Manufacturer: ALPS - listed as such in dmesg, not confirmed
  and not specified by manufacturer

  The touchpad is incorrectly detected by the kernel during Ubuntu 14.04
  x64 installation. The touchpad never worked correctly. It is only able
  to register button clicks and move the mouse pointer. Scroll, taps,
  multitouch, etc are not available and do not show as available option.
  "Synclient -l" returns "Couldn't find synaptics properties. No
  synaptics driver loaded?" Actually, anywhere I looked, the touchpad is
  just listed as a PS/2 Generic Mouse.

  I also used dkms to install the extra ALPS v7 kernel module from
  he1per/psmouse-dkms-alpsv7 on GitHub. Still, the kernel was not able
  to detect the touchpad and enable any of its functions.

  I have included the required debug logs in the attached
  debug_logs.tar.gz file.

  This bug has been confirmed on AskUbuntu by several users and several
  unanswered support requests.
